NGK BKR7EIX plugs are the best.  Alot of people have been having problems with the Densos with tips coming off.  I personally have had no issues with the IK24's.

I can only confirm what Alex has said as I had Denso Iridiums and ended up going back to OEM Bosch ones after the tips burnt out after just a few thousand miles.

I have a set IK24s waiting to be fitted.  Should I exchange them for the NGK BKR7EIX?

Just spoke to Opie Oils where I bought a pack of four from...and they have never had any reported problems.

Neil, Denso Iridiums are the way forward sir. I changed to these 5k miles ago and they have been superb up to now with no problems so far. Tim has them too btw.  :drinking:

Question is why did the others have problems with the Densos?  Bad batch, or was it the remap?

Avoid bosch super's on a modded TFSI. When i drove my car slow for a few miles and then hard it would missfire awful but would clear if kept driven hard until i drove it sedate again.

 Put the NGK iridiums in and runs very sweet.

Would these be the right spark plugs for the GTI 200 with mods?

 IK20
Denso Iridium Power Spark Plug (5304)  By using a 0.4mm diameter iridium alloy center electrode and a special grou... 

instead if the ik24's?

please correct me if i am wrong????

Ok, just fitted the Denso plugs today...and boy do they make a difference!!!  :evilgrin:

My turbo gauge used to peak at 17-18 psi or so.  Now it goes all the way up to 20 and beyond... wooooaaah!  :driver:

Stick with the OEM factory fitted Bosch FR7KPP332 Platinum jobbies.  I think the gazillion miles of testing VW and Audi have done on these engines, along with Hurdys mega tuning efforts prove these are more than upto the job.

T_T are you politely suggesting I remove the Densos and go back to a set of OEMs?

That is your call.  However, VW (actually, it is Audi who carry out the vast majority of engine development for the VW Group) test and fit spark plugs from all makes - Bosch, NGK, Beru, AC, even Champion - and then specify the best one.  If Densos were as good as they claim - how come NO Densos are recommended by VW or Audi for OEM fitment.

I've been in this game far too long to fanny about trying to chase the 'best' spark plug.  I have never, ever found an OEM spec plug to be unsuitable.  But I have come across many a non-genuine or non-OEM spec plug which has caused issues.

And Densos seem to have a similar but limited 'enthusiasm' in the biker community - but again cause frequent probs.  NGK are by far the best plugs in bikes - from both japs and italians.  I won't include Hardly Davidstows - because they are just two-wheeled tractors!

If you have gone for Densos, then I might politely suggest you have been swayed by marketing over engineering.

ETTO, though.  :smiley:

Call it passion - call it whatever you like.  Just tap up your friendly VW or TPS parts person - and ask them if ANY Denso plug has OEM approval.

And just to clarify, VW/Audi frequently list two competing plugs to satisfy individual preferences - for both the GTI and the RS4 - both Bosch and NGK plugs are listed.  On other engines, that choice may be sommat like Beru or Champion, etc.

The people who have had problems with the Denso IK24's burning out are the ones running higher power stage 2+ on K04's. Maybe you will be okay with the Denso's on a K03, but I can't say for sure. It just so happened that the Denso's started to fail when I was at the Nurburgring in April and so they killed my outright lapping ability. I had them on for around 3k miles and they were done. The OEM Bosch's simply took everything I threw at them and still looked virtually like new whenever I had them out to check :happy2:

I'm running the NGK iridiums and they are good though. Car runs sweet with my mods. Those bosch "super" ( i'm guessing they are not the same as the bosch OEM's?) They were absolutely awful!

Bosch Super are generally a 'consumer' plug like what Halfrauds sell.  OEM Bosch plugs generally don't have any fancy 'padding' names.
