WHY
I had a misfire on cylinder 3, diagnosed when I went on Awesome's rolling road. Spark plugs hadn't been changed for 18k miles or so so i thought it couldn't do any harm. Awesome also suggest that any tuned car runs the colder spark plugs. They even fitted them to a brand new Stage 1 Golf R which was misfiring and it cured it (apparently anyway).
WHICH ARE THE RIGHT PLUGS FOR MY CAR?
I was reading from the NGK website about heat gradings. They say that for every 75 - 100 bhp increase you should go a step colder. That being said the old standard heat range was six for a 2.0 tfsi. Based on that the 7s would be good for upto 300bhp and anything over 300bhp the 8s. I have 8s and have about circa 260 to 270bhp. I do lots of short runs now I have moved so i am thinking of switching back to the 7s. As the plugs will never reach the 450c temp it needs to burn of the carbon and I very rarely do long high speed runs and no track driving. I have copied a link to the article I was reading.

SOURCING
Initially I was going to take advantage of Awesome's offer of 4x spark plugs for £32 delivered, but with the kind help of Jaywoo-GTI i was directed towards this eBay listing:
http://www.ebay.co.uk/itm/320797953741?ssPageName=STRK:MEWNX:IT&_trksid=p3984.m1497.l2649
Items delivered quickly and safely wrapped, and for £10 less than Awesome: awesome! (Or not, as the case may be :rolleye:)
FITTING
http://www.golfmkv.net/blog/archives/9#
i didn't have the tools (was short an extension for my socket set), so popped it down to National Tyres in Newcastle-u-Lyme where Richard quoted me around £10 to do it for me, but he couldn't do it there and then because of bookings. Instead he offered to lend me his tools so I could do it myself.
Got the coils off, at which point i noticed one of my coils (cyl 4, not the one misfiring) was rusty despite being changed less than 3 months ago under the recall:
(https://www.mk5golfgti.co.uk/forum/proxy.php?request=http%3A%2F%2Fdaz.co%2Fmedia%2Fyy209%2Fsub39h%2FIMG_1995.jpg&hash=2a2a03ee3580ee3b759c1f2f3aa6ddb15a7d62b2)
(Advice welcome about that^.) I went inside to ask Richard's advice, at which point he came out to the car and, without me asking, changed the spark plugs for me. When I asked him how much, he said "nothing". Result!
OTHER VERSIONS
OEM
Nology
??? (feel free to add others, i didn't really research it tbh)
PLUS POINTS
1. Cost - OEM plugs are in the region of £45 to buy. These were half the price, and from some of the posts on VAGOC it looks like VAG main dealers sometimes use the NGKs anyway (?!)
2. Misfire gone (!) - so they served their original purpose
3. Increase in fuel economy? - seems that way. On my regular trip to the gym which is 16mi away (don't ask) i got better fuel economy than normal, despite the fact that it was 2deg and my car really seems to suffer in the cold. I was driving like a bit of a prat too, and even stopped off for some V-Power on the way which always hurts my fuel economy average on the DIS.
4. Smoothness? - oh how subjective this is, but the car just feels better.
MINUS POINTS
NONE!!! If your car isn't tuned apparently colder plugs don't get hot enough to burn away deposits and you can get fouling of your plugs. I'll be going Stage 2 soon hopefully, so still happy with the purchase. I'll keep you informed if I run into trouble.
15/3/12 Update - roughly 6k miles on standard tune with no degradation in performance :happy2:
28/8/12 Update - roughly 12k miles on standard tune. Single episode of misfire 2 months ago. Disappeared with no recurrence. No fault codes logged, no problems with cold starting.
14/10/13 Update - roughly 20k miles on standard tune. No further episodes of misfiring. The plugs were changed for Nology plugs as part of a major service and does feel a little more responsive. I maintain that for a routine plug change they are good value and should not be considered an upgrade - at least not on an unmapped K03 car.
SUMMARY
For £21.32 fitted (not including the petrol it took me to drive to the garage) I'd say this is a right old result. Whether or not they make a difference is irrelevant, they're half the price of OEM and do exactly the same job. If they're better that's just an added bonus.

That's some saving over the ones from Awesome and OEM, well done :wink:
-
Ordered :happy2: let's hope they fix my misfire as well :signLOL:

good luck :happy2:

Thanks I'll update once they're fitted
-
ordered, dont need just yet but planning to change plugs in Feb and I like to have thing sin stock in my garage (bat cave to copy RR :grin:)
-
Nice to see they cured your problem, and glad i could help :happy2: (even if you do drive a rich mans golf :P )
-
I fitted a set of these a few weeks back - unfortunately didn't see this post so paid a bit more via awesome!
They've cured my little misfire on idle, and the misfire on WOT at low revs has disappeared
The pops between changes on the DSG have improved too, so all round a winning purchase. Car feels like new again

These cured my misfire under load to :grin: And it's weird that you'd mention the pops as I thought today that they sounded better :driver:
-
Nice write up there mate
Ill be purchasing these and fitting in the new year :drinking:
-
Do you have an engine cover? Water in no4 and rust cool pack is common and I've had 3 or 4 rusty no 4 coils.
Might try a touch of grease to make a better seal.
Good write up. I use the 7s on st2+ and gives the car a new lease of life when I change them. I'm anal and do them every 6 - 10k
Thanks
Mike

Thanks for the info. Nope, no engine cover. I'm gonna change it and as you suggest use a little grease to improve the seal :happy2:

Yeah definitely. There's something tangibly different about the car, but it's not something I could measure objectively
Almost forgot to ask, do you use the pad dampers or an alternative (or nothing at all) and do you get squeezing.
Thanks
Mike
Not sure what you mean Mike
-
ah. i've not fitted my NQS yet, and i was gonna give it a go without the dampers because DaveB didn't have a set for me when i bought... but he said i don't need them?
-
To add, I did 140miles today and these plugs have made the car a different beats. The map is just as it should be now. No hesitation, misfires or other complaints
So pleased :xmassmiley:

Dont you just love spark plugs :jumping:
-
I do, very much :signLOL:
-
There's so many different plugs out there and people rate different ones so im pickled :scared:
Would these be "the daddy" for stage 2+ eddy?
:santa:
-
I would say so Jack
-
I assume these are the right type for an 05 GTI?
-
Yes
However if you are not mapped, it should be said a BKR7EIX is perhaps better as this is the same as VWs stock plugs.
-
Im running a stage 1 revo atm, looking to go stage 2 in the new year, so these ones are GTG?
-
Then these are perfect for what you want :happy2:
-
I was under the impression 7's were the ones I needed for st2+ well just ordered these to try thanks for the link!
Mike
-
7s are VW spec, which are a step cooler
8s are step cooler over VW spec and better suited to tuned engines
Also, iridium is a better conductor than platinum which VW use in their NGK Plugs - Iridium is almost as conductive as copper, but has the long life of platinum so its win win
-
Will see how I get on with them. Cheers
May not go in till spring when the weather allows the engine to be worked safely.
Warren cox wrote a good post on various tried and tested grade plugs over on VagOc
-
I found this thread after a bit of searching having noted my car was missing occasionally at idle after a long run at medium to high loads (extended motorway run, with some B-road overtaking for instance). I have the latest revision PCV flying-saucer-esk jobba fitted.
Mine's a stg-1 K03, so I'll report any improvement to add to the thread's statistics. For reference the plugs I removed are 15k old PFR7S8EG and they look in text-book condition. Whatever the outcome 4 iridium plugs for just over £20 makes them pretty much disposable, so cheers to the OP for the tip-off.
-
I have been running these for a couple of months now and the car hasn't missed a beat.

I would say so Jack
Cheers dude :drinking:

Quick question or two - I know that these plugs are sometimes sold as single units (as they appear to be on the ebay link) as they are used in motorbikes. However, I think the bike plugs come with a different gap setting. Is it the same for these or are they preset to 0.8mm like the 4-pack?
Also, there was a post or two about some folks reducing the gap from 0.8 to 0.67mm or something like that on tuned cars. Is there anything behind reducing the gap (as there is a big danger of damaging the delicate tips on these plugs?
(https://www.mk5golfgti.co.uk/forum/proxy.php?request=http%3A%2F%2Fdaz.co%2Fmedia%2FMy_Leon_Cupra%2FMaintenance_and_Technical%2F99635108801.jpg&hash=ee98964959cf2f1a07ddea9d29c9e5dc67319aec)
The pad damper I'm talkin about ^^
I managed to source 4 of these for my NQSBBK as I was unlucky enough to get a bit of low speed squeel although it may have been a combination of discs, pads and not being broken in enough. These things fixed it no problem anyway. As a bit of advice, if you are going without the anti-squeel shims, use a non-petroleum based grease on the back of the pads like CeraTec. Copper grease rots the bejeeziz out of the rubber dust seals. :happy2:

Can you take the brake talk to another thread please, I will clean this up a bit later.

It was RON ECHT who suggested that gap on the other NGK iridium thread. I bought a feeler gauge but didnt want to damage the plug.

Notes since fitting:-
Idle better.
Fuel consumption unchanged - currently getting between 35-37mpg on the run to work, and saw 37.5 mpg on a 45 mile motorway drive earlier in the week, which is par for the course.
Engine seems to sound crisper, but this may be placebo.
-
Ive noticed the same so it would imply these plugs really do make a big difference.
However my MPG has improved by around 2-3mpg

My mpg improvement has been more to the order of 4-5mpg
-
Mine may be more but I've only driven it twice since replacing them!
-
Fitted my set today and I immediately noticed the engine ran a lot smoother. My slight misfire had totally gone and she even seems more eager! :driver:
-
Put mine in the other day and def smoother! I was running the NGK OEM heat range ''7'' plugs before.

Looking forward to feeling a difference between the 7 & 8
-
Going to get some of these next week I think
-
Have bought some of these today- got them from my local motor factor as a friend runs it, payed £35.
What is the deal with the gapping of them?
IS it best to close them down a bit?
-
Mine were gapped at .8 I think.
-
I wouldn't touch the gapping. Mine are perfect from their purchased spec.

Mine were all over the place, that's the only reason why mine were done!
-
0.8 should be the standard gap. I always gap them down to 0.64.
-
Would that gapof 0.64 also apply to the 7 heat range. I am stage 2 k03 and am going stage 3 soon. I will get some 8s once these need replacing.
Cheers Matt
-
I run 260hp gti and fitted 8s at the weekend. Measured them and are set at .7. They seem fine
-
Just ordered these. Looking forward to fitting them. Good price.
Thanks for the link. :happy2:
-
Guys,
Any good advice on the best place or URL's to buy these?
Also, what would the best gap be for an S3 at stage 2+?
:happy2:
-
Ebay link on the first page
And .7 as they come should be fine.
-
ill be going stage 1 soon, on a GTI K03, so will it be worth getting these plugs?
-
Aye they are good for any mapped GTI
-
Encouraging results from all that have fitted, so ordered and my set are sat on my desk. Will fit in the next couple of weeks :happy2:
-
I went for the BKR7EIX found the BKR8EIX was to cold
-
I went for the BKR7EIX found the BKR8EIX was to cold
how do you mean? what was the problem with the BKR8EIX?
-
I found the BKR8EIX would foul up due not getting hot enough to burn off the carbon deposits
-
I spoke to Revo about the above differences and was to as long as the car is given a good spirited drive occasionally :driver: running '8's will not be a problem,
the '7's are more suited to a standard gti.
-
Got the coils off, at which point i noticed one of my coils (cyl 4, not the one misfiring) was rusty despite being changed less than 3 months ago under the recall:

(Advice welcome about that^.)
There is a special grease which the stealers should have used - it has only been out about three years - so VW stealers might not yet be up to speed. :chicken:
Here we go - G 052 141 A2 - its only a dinky 20ml tube, and you'll need about 15 beer tokens - but if used correctly, will stop coil rusting, and make insertion and removal much easier.
-
0.8 should be the standard gap. I always gap them down to 0.64.
Why? Is that not old skool practice? :booty:
That was the kind of adjustment when you say, increased the compression, or massively increased turbo boost - and more importantly, with old skool ignition systems with single coils. Modern super high voltage multi coil systems shouldn't really need plug gaps closing at all. :happy2:
-
ill be going stage 1 soon, on a GTI K03, so will it be worth getting these plugs?
Stick with standard plugs on S1 K03 - I tried colder plugs on mine, and I got cold running fouling and misfire.
-
Would these be ok on a standard 2.0 TFSI K04? Or better to use standard plugs and then replace with these once Stage 1 Mapped?
Thanks :happy2:
-
If its a K04, should be fine :happy2:
-
brilliant :happy2:
had P0303 misfire cyl 3 code several times over the last few days, reckon after 59k miles I better change the plugs :innocent:
lets see if they help...

Mine are going great on my standard KO4 currently! :happy2:
Should be mapped by the end of this week though! :wink:
-
Which map?

Mapping these 2.0T engine really show up weak plugs.
As some of you may know , at the JKM RR day my car was showing a missfire on cylinder 3.
This morning I went back to JKM for a service and for a set of these plugs to be fitted. Hey presto no more misfire!!! The car feels so much smoother and pulls so much better.
Unbelievably VW suggest a change of plugs every 40000 miles which is a joke. On any car , especialy a remapped car , acording to JKM it should be every 20000 miles. Lesson learned...

Excellent - glad that it was the cheap fix hoped for on the day.
Did JKM fit temperature '8' plugs, or '7'?
The chaps in the JKM dyno thread suggested JKM don't like to fit the 8s, yet that's what JKM had in the display cabinet. I assumed they'd fit '8' to a mapped K04 as it seems to be the done thing these days.

Not sure if it was 7 or 8 - but I would like to think it was the 8s. It dosen't state on the invoice 7 or 8 just NGK Iridiums. I guess I should have asked the question. Anyway the car now drives and feels as it should so I'm more than pleased :wink:

Just put my order in for some :happy2:

I'm glad to see this has helped so many ppl :happy2:

done about 40 miles on them after fitting them last night and the car idles so much better and i have race mounts so its made a massive noise change to the car and also car seems to pull smoother too.The wife also said its less noisy on tick over :smiley:

got to love the wife test,whenever I do any performance mods I never tell her. had it stage 2+'d the other day and she came back saying the car seems different it makes more of a whoosh noise and accelerates quicker I nearly wet myself . justified the mod to me lol
-
Checked at VW and they said the eddie wont need plugs until 60k :signLOL: think i will be ordering some 7's straight away as im still standard and will be for atleast the next 6mths.
-
I dont know why dealers say 60K.... :stupid: :stupid:
-
I think most have shown in this thread the car benefits from having these fitted way before then!!
-
Guys
Are these plugs only for tuned/re-mapped GTIs?
Pretty sure my standard hasnt had plug change so would get some if they suited my standard GTI.
thanks
-
as it turns out i bought the 8's but have never fitted them!
I got the car serviced by a VW dealer (major service) which included OE plugs
for what its worth, mine were 59,000 miles old and I was having P0030 Misfire Cyl3 fault codes on acceleration. These have now gone and my boost levels have increased :surprised:
So old plugs had a really detrimental effect on my car.
For any GTI get new plugs regularly, the recommendation on here seems to be 7's for std cars and 8's for remapped.
-

Sorry to be so ignorant but what should i order/ask for then - i dont the 7s reference?? Do you still recommend NGK Iridiums?
I defo could use new plugs in my standard GTI.
Thanks
-
The part number is BKR7EIX but VW dealers dont sell them. If you are staying standard then the 7s will be fine for your car and even fine on a remapped ones. I run the 7s and I am stage 2+. Though I might fit a set of 8's to see what difference they make to my car as I change them every 10,000 miles. Even if they dont really need changing, I still do when I change the oil and they are inexpensive to replace. The only problem with the 8's is they may foul if the engine doesnt get up to temperature with local driving.
-
I got a set of the 7's off amazon for around £24 posted :happy2:
-
Fitted mine today, cured my misfire under load :happy2:
Bit worrying that the Bosch ones that VW fitted last June were failing after only 8000 miles :surprised:
-
Got some 7's in the boot might put them back in for tootling round and use the 8's for track days etc
-
well I've fitted my new NGK 8's and I canT tell there's any difference between the stock OEM bosch plugs in performance terms.. And in terms of starting or mpg.. :confused:

I managed to get a set cheap, so I will be fitting these tomorrow along with my new N revision PCV and oil service. Hopefully should make a nice difference. I shall report my findings.
-
Fitted them today along with my N revision PCV. The car has no more flat spots and pulls like a train :happy2: Plus it pops and burbles more on overrun :evilgrin:
-
Quick update about these:
Must have run about 5k miles now on standard tune and no ill effects thus far

Been shopping round for these, camskill have an offer on at £8.16 each with 10.5% off with orders of 8 or more.
Amazon seem to be out of stock all the time, any other suggestions as i have 8 to get, to change both cars. 40k on the same plugs is just wrong.
-
Try Opie Oils as I got mine from there very cheaply.
-
sparkplugs.co.uk :smiley:
-
The eBay link @ the start of this thread is the cheapest I've found :happy2:
-
They've put their prices up tho...
-
There is a company called the green sparkplig company and they sell them for £5 and a few pence each. So Opie Oils price matched that with free postage :happy2:

ebay was where I got mine, couldn't be happier - bought on this review and happy I did - cracking product
-
Fitted these due to having missfires under wot, but had to gap them from 0,8 to 0,6 to stop the missfires :smiley:
-
Just a triple check guys (haven't got round to fitting them yet);
After all the discussion around the 7's/8's and the difference in results with the different gaps, will the set of BKR8EIX's that I bought be setup correctly out the box for my completely engine standard k03 GTI on a 2006 plate?
Thanks.

They should be set from the factory so should be okay.

Also, iridium is a better conductor than platinum which VW use in their NGK Plugs - Iridium is almost as conductive as copper, but has the long life of platinum so its win win
....This is exactly what JKM told me when I had my usual 20k-mile spark plug change to NGK Iridiums. I'm running Revo Stage 2.

Just a triple check guys (haven't got round to fitting them yet);
After all the discussion around the 7's/8's and the difference in results with the different gaps, will the set of BKR8EIX's that I bought be setup correctly out the box for my completely engine standard k03 GTI on a 2006 plate?
Thanks.
Only when pushing the envelope you have to gap them to 0,6. I got the info from VrsAlex and it worked for me as i had some slight missfires in mine even with these plugs fitted :smiley:

What's pushing the envelope mean Jake? :scared:
You're a k04 and running several engine mods aren't you, so I'm unlikely to need to change them for my factory setup, right?

I'm trying to max out the K04 on the Cupra engine with what mods i can get my hands on, you should be fine, just using these over the 7 helps a great deal :happy2:
-
On a standard, a stage 1 car or if you only do short miles then I would stick with the 7's. The 8's are just too cold and this was evident when I removed them from my car. The 7's have since been burning perfectly.

Enough with the pictures Robin.

I may be wrong but all this "specific" spark plug nonsense is exactly that.
Im guessing a lot of folk have bought these, when actually a set of OEM plugs would have been absolutely fine.

....I have my spark plugs changed every 20k miles (K03 Revo Stage 2) and have in the past used OEM plugs but this time asked Jim at JKM what he recommended. He said that OEM Platinum would be fine but Iridium would be better, explaining the differences, also with Copper as discussed earlier. It wasn't a question of whether a colder plug or not unless a more modified car. I tend to take his advice, hence Iridium heavenly 7.

Having had massive missfires with stock plugs when i tried boost 9 on my sps on both gti k04 software and the current beta software i can say these have made a difference on my car. up until then i have had same opinion as RR :smiley:

On your state of tune rich, oem ones are fine, but stage 2 and up , 8's are better, as I've found out on my own Stage 2 car.

But how do you know that a set of fresh OEM plugs would have 'felt' better?
Back to back dyno testing anyone?

I'm no longer getting vcds errors, of lean running since installing 8's. Also the car starts from cold with a flick , rather then not wanting to start very well from cold. some people have said about improved mpg, but that I haven't noticed any difference .

There is a back to back dyno test on VAGOC looking a Okada coils
Compares OEM coils/OEM plugs vs. OEM coils/uprated plugs (can't remember which but think they might be these very ones) vs. Okada coils/OEM plugs vs. Okada coils/uprated plugs
Verdict - plugs make a difference. I think the Okada/uprated plugs was making 15bhp more or so. Most of this was down to the coils, but there was a measurable difference between the plugs in all set ups
anyway, even if they made NO difference they're cheaper than OEM so there's still no reason to go OEM.

Am quite confused on whether to go for the 7 or 8's as this thread is completely mixed opinions, I live in london city so alot of city traffic and i am going to go to stage 2+ with k04, What would be the best suited to me then?

Stage 2+ would benefit from 8s

I have a nicely tuned KO4 and now running OEM plugs and i don't have any of the above symptoms. I was running Iridium 7's but got hold of OEM ones and my car runs just as good.. Personally i think OEM vs 7 vs 8 is not going to make much difference that it's worth the hassle.. This is my experience driving mine for 120k
I have found though in my experience the 2.0T is fussy about plugs. Put in Bosch super's once and they didn't last 5k
You can't go wrong with OEM's anyway.
I always know when mine needs new plugs. Under WOT i get missfires and clouds of black smoke out the exhaust lol

I was reading from the NGK website about heat gradings. They say that for every 75 - 100 bhp increase you should go a step colder. That being said the old standard heat range was six for a 2.0 tfsi. Based on that the 7s would be good for upto 300bhp and anything over 300bhp the 8s. I have 8s and have about circa 260 to 270bhp. I do lots of short runs now I have moved so i am thinking of switching back to the 7s. As the plugs will never reach the 450c temp it needs to burn of the carbon and I very rarely do long high speed runs and no track driving. I have copied a link to the article I was reading.

I fitted the 8's to my ed30 at stage 2, and I've since changed back to the Bosch OEM 7's and she runnings much stronger at top end, maybe a new dodgy plug but the car never seemed happy with them fitted. Perhaps stage 2+is better suited then at stage 2 perhaps.. :confused:

NGK Iridium 7's is what JKM recommended for my Revo Stage 2 K03 GTI.

so that would tie up with my findings too. :happy2: though my bluefin doesn't request 130 bar , only 110..
8's for stage 2+cars, I'm guessing due to high temps and higher fuel demands etc

So all the crap and 9 page thread about cold spark plugs is ballony...... I thought so ;-)
-
So all the crap and 9 page thread about cold spark plugs is ballony...... I thought so ;-)
i never intend for this to become a debate about whether there's any benefit - my point was always that they're cheaper and hence are better £ for £ compared with OEM.
however 2 tuners (JKM and Awesome) seem to prefer these NGKs, and R-Tech promote Nology plugs? plus a link that demonstrates that plugs do seem to have an effect. there must be something to that...
-
Just to check the part numbers for a gti engine- BKR7EIX is 2667? And the BKR8EIX is 2668?

.
I know that I have advised this before, and probably already in this thread, but I believe it's very good advice to change plugs every 20k miles on a remapped car, regardless of which plugs they are - It maintains a consistent spark and helps keeps things running smoothly.
-
would you also advise changing stock plugs to ?????? when going from stock map to a Stage 2 (for example)? In other words, i've had my stock plugs now for about 18mths, but only had remap for a few weeks.... :confused:
-
.
Although VW don't suggest such a regular change of plugs, I still think it's a good idea. Afterall, VW are not writing their Handbook recommendations for anything other than their ex-factory cars.
As you are now running with a remap and it's also been 18 months (depending on your mileage) I would change plugs. I'm not suggesting that you'll get problems if you don't but only that's it's good maintenance on a tuned 2.0T FSI car.
-
well at idle its quite jittery now, since the remap i mean, like it's coughing (from the exhaust), although of course this could be to do with fuelling!!??
-

....First and easy port of call is to change the plugs (I'm assuming from your earlier post that you haven't recently done so).
Fuelling issues usually only manifest themselves when the throttle is under load and the fuel pump is gasping a bit. The ECU does quite a bit to to automatically correct this but it's why you can get fuel cuts and it's why remapped folks usually upgrade their HPFP.
Modding is a slippery slope. You might have found the slope less steep if you had upgraded via Stage 1 instead of straight to Stage 2.
Which air intake are you using?
Someone with VCDS can probably diagnose issues for you.
-
had the plugs changed about 18mths ago (whilst on stock map), so i am assuming with your bog standard Golf plugs, then had Bluefin Stage 1 a few mths later, so that's why i decided to go straight to a custom Stage 2 remap with R Tech a few weeks ago, after returning to stock map of course! Don't get me wrong now, the difference is like chalk and cheese in terms of 'poke' and torque, it's just the spluttering (when idle) i get through the car/exhaust now that's making me ask questions!? I have a Twintake, you responded to me about this on a different thread about 15 min ago, lol! :drinking:
I am going back to see Nick in a few weeks, but in the meantime he has advised that i change the N75 (see whether i can attain more than the 256bph i now apparently have!?)

If it ain't broke...don't fix it... :smiley:
leave them as they are chap. nothing wrong using Bosch products IMO.
I've tried NGK and found them worse, but that was the 8 heat rating and not the 7 stock rating.
I would only put cooler plugs in if your running higher fuel pressures. Revo Stage 2 and 2+onwards .
bluefin 1 and stage 2 on the 7's.
-
Well I now have an R Tech custom remap Stage 2, and tbh I have no idea wat type plugs I currently have, as the car was serviced with Kwikfit (oops!!!) I am waiting on them to get bak 2 me to tell me what type plugs they 'allegedly' fitted, then base my next move on that! :$

^^^^
Andrew,
Take Nick @ R-Tech's advice about plugs - He knows your individual car and he knows his stuff :happy2:

Will do Robin, although he is only advising me 2 change the N75 and the fan, etc, its my choice for the plugs.

Found out the other day that i had 6s in my car, so as now at R Tech Stage 2, changing to Iridium 7s (NGKBKR7EIX) tomorrow, wonder if i'll notice any difference at all!? :surprised:

....Brighter and smoother on acceleration perhaps but any difference will only be very subtle and Miss Placebo will be flashing her thighs at you in your passenger seat. It's not gonna feel like you just had a remap!

What power are you running?
-
Just a bit of feedback.
I fitted some of these about 3 months ago and I think they are shot already.
It won't be the coilpacks as they are fairly new and there is no fault but I think they are just to cold and I get a bit of hesitation at low revs accelerating.
They have been ok but I am going to put the OEM back in and see what happens.
Over and out.

I'm running on NGK Iridium 7's on a Revo Stage 2 K03 GTI and without any problems. I was advised by JKM that 7's were the most appropriate for my mods/power.

have you taken them out? What do they look like?

I spoke to the manufacturer directly last week and they have advised if the 7s are too cold still, there is an exact match but in 6, so i will just see how the 7s today fair!?
-
Are you running a map or not?
-
Yes, i have an R Tech Custom Map Stage 2, only had it for about 4 weeks now, and i said, have been running on 6s (Platinum i think) for last 15 mths or so. Idle now is quite rough, ie. since the remap, but that could be down to a number of things, but for £30 or so, i think it might be worth taking a chance, see if it improves!?
-
15months... how many miles? Plugs will degrade quicker as your running stage 2.
Worth a shot at some new '7's maybe. :happy2:
-

....Exactly why I change my plugs every 20k miles. :happy2:

TBH, i only do about 6000 miles per year, so have done perhaps 8000 in last 15mths or so. I've nothing to lose i guess by changing to the Iridium 7s...
-
speak with Nick - i think he prefers Nology. they're more expensive tho, £40 a set
-
did a bit of research on these on ye olde web and kept getting the words 'snake oil'!! :popcornsoda:
-
Since refitting the 7s my mpg has gone back upto 37ish on a run. I could barely get above 30mpg with the 8s fitted on a run. The engine is running smoother now and seems to pull better. I think for normal driving the 8s are probably a bit too cold. When I removed them they were fouled so they werent getting hot enough to burn of the carbon deposits.
-
I found the same . Better on 7's then 8's too.
-
I fitted these Iridium 7s about 10 days ago, after having Platinum 6's for the previous 16 mths. To be honest, i'm not sure if i will stick with the 7s!? Maybe it's just me, but i've found it takes 2 or 3 turns to start in the morning now; with the 6's it started 1st time hail, rain or snow! This morning (last used on Saturday) it took about 3 turns AND started quite gingerly, does anybody else have this?? It just seems ironic that all this started IMMEDIATELY after upping to the 7's...... :sad1:

had them fitted by an independent VW, etc Specialist and as far as i know, they were 'gapped' at the standard 0.8mm, which apparently is supposed to cover 99.99% of situations. Wondering though, although wouldn't even know how, if i should change the gap!!?? :confused:

^^^ not sure if you read the earlier post Robin, but think that's the point, he's having trouble starting the car. :innocent:

cheers Freedy, yes, if i leave the car for more than 24hrs, it's slow in starting, totally different to how it was with the Platinum 6's. I wonder if it's got anything to do with the fact that the car had a custom map 5 wks ago whilst the 6's were still in!? Just seems a huge coincidence in my eyes anyway that i've only had starting problems since upgrading to the 7's... :sad1:

I had them fitted by a very reputable independent specialist in S. Yorkshire, so can't imagine they weren't fitted correctly and/or tightly, although i wouldn't have a clue how to check tbh!!?? Ref the battery, how does one check the life left in one of these?? :rolleye:

i think it's likely the new plugs have highlighted a weakness somewhere else in the electrical system that was being masked before by the warmer plugs

oh great, lol, all i need, a weakness such as perhaps??????

battery and coil packs spring to mind for example

well battery has never been changed in 7 years, and i think my coils were changed back in 2007 (perhaps 2008) under a recall. Should either/both have been changed by now??? :confused:

My opinion - Go back to these people explain your problem - They should have no problem checking the work they carried out is 100% and also checking to see what your 'new' problem is and if it is related at all. Rather than chase this problme ensure it is not related to the plug change first.

Well bang goes that theory surely!? My 7+ yr battery has a Start Capacity of 84% (Good Battery), and my Alternator Test stated Ripple OK, whatever that means, but showed 14.22 V Good!

have you checked your coils?
my 7 year old battery has no problems at all with colder plugs
-
And does start with first turnover every time may I ask? Had the coils changed under Recall bout 4 or 5 yrs back! Maybe I should just get the Okada Plasmas, lol!? Expensive way to check thou! :-S
-
it fires up right away, even from cold
-
Hmmm, mine did on 6's, maybe I should revert back!?
-
Perhaps when installing one of the plugs they damaged an electrode, which is why it is not running correctly. I found my car ran better with the 7s than 6s. I tried the 8s for a while but they started to foul so I switched back the 7s and all was good again. If you have your old plugs I would refit them and see if the problem goes away.
-
Just a quick update on this - I've got an unmapped K03 and i still haven't had any issues with this plug. done over 12k miles on them now. varied driving conditions, but limited spirited driving due to not being able to afford petrol and mainly motorway miles.
i had a single incidence of a misfire whilst sat in traffic a couple of months ago but has not repeated itself since. no fault codes. no problems with cold starting.
-
I had my BKR8EIX plugs in for a similar mileage on my K03 also, they seemed to work well and have had no misfires but when I checked them recently I found this-
(https://www.mk5golfgti.co.uk/forum/proxy.php?request=http%3A%2F%2Fdaz.co%2Fmedia%2Fac115%2Fgocartingd%2Fa64579974ddd4f5bed71f16a83c30a54.jpg&hash=207872050cbe68761aca48f6ff8a928ef67d9ff7)
They were massively coke'd up and had loads of carbon deposits. I changed back to the hotter "7" plug and since the engine actually feels like it's got quicker which may have over the last 600 miles burnt off excessive carbon deposits. Worth thinking about, they may not be any noticeable running issues but since changing back the engine seems stronger.

....I think this illustrates very well why it's good practice on a tuned car to more regularly change plugs than suggested in the car Handbook. I change mine (iridium heavenly sevens) every 20k miles.

Thats how mine looked. Unless you drive the car hard you wont burn off the carbon deposits with the 8s. These are a plug more for track days than normal driving. Since fitting the 7s my car hasnt missed a beat and feels loads beter to drive.
-
Mine were the same as I had a misfire so pulled the plugs out and everyone fecked
-
I too ditched the 8's back to the oem 7's and confirm mine feels a lot stronger especially at top Revs.
-
I may be wrong but all this "specific" spark plug nonsense is exactly that.
Im guessing a lot of folk have bought these, when actually a set of OEM plugs would have been absolutely fine.
On your state of tune rich, oem ones are fine, but stage 2 and up , 8's are better, as I've found out on my own Stage 2 car.
Ohh.... looks like i was right after all... :innocent:
-
Yes rich, alot of stuff that becomes the overnight must have , sometimes pays dividends to leave the car as the manufacture intended..... Best stop there.... :signLOL:
-
I had a brief encounter with Denso iridiums when I had the ED30. I soon moved back to the stock Bosch jobbies and they are in my opinion the best plugs for the job up to stage 2+. They lasted longer, coked up a LOT less and gave a better running engine at start up and when hot. :smiley:
I've not tried the NGK iridiums, but I doubt they will give any discernable advantage over stock. :smiley:

I may be wrong but all this "specific" spark plug nonsense is exactly that.
Im guessing a lot of folk have bought these, when actually a set of OEM plugs would have been absolutely fine.
On your state of tune rich, oem ones are fine, but stage 2 and up , 8's are better, as I've found out on my own Stage 2 car.
Ohh.... looks like i was right after all... :innocent:
So what your saying Rich is OEM ftmfw
-
So for everyday pottering about too and from work and now its getting towards winter its Prob best i switch back to the 7's.
-
I still think on Stage 2 these offer better performance. I had some serious issues with stock plugs on a stage 2 map.

Weird as I have the same map/car setup and now find the opposite :signLOL:
-
My mk2 Leon cupra seemed to run ok on the 8's on a stage 3 map (350 odd bhp) not had a look at them yet tho,
Probably gonna change back to the 7's for winter tho
-
I think the 8s are fine if you do long drives and use the power a lot. I now only really do local commuting and the 8s are too cold for that. They carboned up very badly and made my engine run very harsh. Initially they were fine when new but after carboning up they werent. I switched back to the 7s and the car is running fine again. The 8s are an ideal track day plug when you want to use the power for longer but I think the 7s are more suited to road applications no matter what power level or turbocharger you have fitted.

Sorry to resurrect and old topic but for me its quite current, so I thought I'd post my experiences.
I have 2007 Octavia vRS 2.0TFSI and the car currently has about 58k miles on the clock. I wanted to carry out some self maintenance and bought new coils and plugs from Awesome. The car had original Bosch plugs and coils and its been fitted with a stage 2 tune. My problem with the car has always been that every now and then the car has some trouble starting when its cold, so I figured that it must be the plugs. I've read quite a few topics about this and realized that cold starts is pretty a common issue for the TFSI engine. Therefore, changed the coil packs and the plugs and now it does it almost every single time. So, based on this I probably will be changing the plugs to either 7's or maybe even 6's. The problem is pretty much the same what gigolo456 had on the previous page.
-
My plugs were finally changed last month for some Nology ones during a service with Alex at AKS Tuning. In isolation I was very happy with the performance of the NGKs, but having had them changed I feel my car is more responsive now. I did have several things done so it is difficult to say exactly what the reason is, but Alex feels it may have been the plugs.
I don't withdraw my recommendation for them - they are half the price of OEM ones and last about as long. But they are not upgrades and should not be treated as such - at least not on an unmapped K03 car.
I would have liked to have done a similar review on the Nology plugs but sadly I don't drive my car regularly enough anymore to be able to make in depth observations.
-
Just read the whole thread, so many conflicting views :confused: Still going to give them ago on mine :driver:

Further to my earlier post, I can confirm that plugs had nothing to do with the start issue. It was actually the battery. Idle is definitely a lot smoother when compared to OEM plugs but other than that it is very difficult to feel the difference. I might still get set a of 7's as I feel that the 8's are a tad too cold for my daily commute (i.e. won't reach optimal operating temperature) and might cause unnecessary carbon build up.

So for a Stage 1 GTi (250bhp) would heat rating 6 be best?
Thanks

Sure is... although you need more of them than Iridium/Platinums.

I fitted the 8's last September and here is the result. Bought a set of 7's and installed them today so let's see how they work.

These were the OEM plugs that I took out and replaced with 8's. The OEM plugs had about 55k miles on them

Some carbon build up on the end of those 8s.
-
Indeed, although not as much as TT-Turbo had on page 13. Changed these since the past two weeks I've been getting odd idle when cold starting the car (we had -11 Celsius this morning). Other than that never had any other running issues with them. VCDS logs pressure drop between turbo an TB at ignition. Give it minute to settle, erase codes and all is good... :stupid:

I agree. Currently idle a lot smoother but that's due to brand new plugs. I think I will order a set of original plugs before the summer and just stop there as I never had any issues with the OEM plugs.
-
My 8's have arrived :happy2:
-
Stick with 7's imo. 8's are crap for day to day. Foul up. 7's burn so much cleaner.
-
What he ^^^ bloody crap for day to day driving
-
Nice info on the NGK plugs..will be trying these next... :happy2:
-
I was going to get the 8's but reading through the pages I might be better getting the 7's I have a remapped ED30 but I'm only doing short journey and the engine barley gets to temp the tine I get to work

Where are you guys getting your NGK 7s from? I've found them on Opie Oils but £45 seems a bit steep!

For future reference I got them from Euro Car Parts:
http://www.eurocarparts.com/search/408992990/p/car-parts/?408992990&1&1&000301
I cross referenced their SKU number with the one on their eBay advert that confirms these are BKR7EIX
£33.71 with UPS next day delivery :happy2:

Definetly carbon build up, but what has happened to the plug in the first pic. Perhaps some water getting in? I know another Cupra owner who had the same issue of water getting in.

I'd be concerned about that rusty plug. Water getting into the plug bores is responsible for the engine fires I hear about. :/

they were in a hell of a state like,i think the water on the plugs etc was more down to me cleaning the engine bay,went abit mad with the degreaser and hose lol
good heads up on the misfire though m8 cheers

do you run without an engine cover? one of the centre cylinders (2 or 3, can't remember which) can accumulate water which soaks into the liner on the bonnet and drips into that cylinder if you run with the engine cover off. That might explain the rusty plug.
Since I wrote this review, I had the NGKs swapped for Nologys on vRSAlex's advice. He has since withdrawn this advice and fitted NGK 7s to my car. I can feel no perceivable difference between the 3, and my plugs looked nothing like yours after considerably longer use.
-
Had mine in for 2400 miles on stage 2 tune and look completely fine to me, car starts, idled and run like a dream.
I will be changing them for a fresh set for piece of mind n all that around September time just to stay on top of maintenance
-
whats the general opinion then guys??
standard edition 30. had my plugs changed at last vw service 3000 miles/ 6 months ago. any point swapping to these or are vw ones just as good.
-
For standard car the oem plugs should be more than adequate for 20k miles.

Just ordered a set as my idles a little poor and I'm guessing the plugs have had it.
Will pull them out and have a nose when weather gets better haha
