Suspect coil pack - Failure
« on: November 01, 2018, 07:26:51 PM »
Just after peoples thoughts.

Changed my spark plugs today, bought the NGK Iridium ones from Awesome GTI.

Straight forward swap, noticed on the 1st pack I pulled had wierd rust type stuff on the end, pulled the spark plug out & that was the same.

Ran out of time today but will pull the plug whilst the engine is running tomorrow.

Wondered if anyone has experienced this & it's just the pack.

The clean spark plug is what the other three looked like.

You water ingress on that cylinder.  Check the seals on the coilpack.

So I changed back to my old spark plugs, car is running right as rain again??

Just spoken to Awesome & they're saying BKR7EIX plugs are for mapped cars & that I should've got the BKR6EIX?

Sure I've read that 7's are the ones to have & 8's are for stage 2 +.

Bloody annoying as I can't send them back now!

Phoned them again as I double checked there website, the plugs are for stock & tuned engines.

I'm sending them back, they're going to check them out.

I use those on my standard engine and it runs better than the stock plugs.  I crossed referenced the oem plug on NGK's website and it's also a heat grade 7.  I don't know why the tuners say Iridium 7s are for tuned only, it's not true.

Not sure why yours doesn't like them.  Did you push the coils down hard?  The 'click' isn't as positive as the OEM plugs.

Yeah thrown me too, as I was sure when I ordered them that they're right. I just think the guy was trying to fob me off, when I called back & questioned him he put me through to another department.

See what they say...

I did make sure I'd pressed the coil pack  in, was sure I'd done something wrong double / triple checked everything. Even pulled a plug whilst the engine was running which made it even worse. I was so close to ordering new coil packs glad I double checked the old spark plugs!

Awesome have found two spark plug gaps to be incorrect.

They're sending out a new set.

Hmmm, iridiums are supplied pre-gapped to stop people from damaging them. I checked the ones (7 heat btw) I bought before fitting this summer and they were all set accurately & identical.

It is strange, I specifically got them as they're pre gapped. I'll check them all before installing them this time.

They did ask me if I'd dropped them, definitely didn't, I've also got the propper plug socket with the rubber insert so they don't drop into the engine.

Glad you got this sorted. I did both plugs and red coils at the same time and found the car to run better. Smoother and more responsive. I got the Eldor genuine red coils with all the parts numbers etc printed on them for @£85 from a seller on ebay and the old coils sold on pretty quickly.

Thanks, so am I! Was good of Awesome GTI to send new ones out, this day & age I guess so many people take the piss.

I will change the coil packs, but with shelling out on pads, spark plugs & cam follower they'll just have to wait a little longer
