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.

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.

Got a link for that comparison?

Stage 2+ would benefit from 8s

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 .

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

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...
