Spark plug NGK or Denso

if you want some good plugs, get some denso IKH24, they are 1 step cooler than stock plugs.. I change mine out every 20k miles..

Did my plugs 4 months ago with NGKand they still feel great.

I run NGK BKR6E's in my rabbit. I have had the best results and longest life from the NGK plugs. To the point that is all I run in any of my cars! LOVE them!

IKH 24 plugs with stock coils work just fine. No cutout, rough idle or misfire.

Replaced stock with denso ihk24.

If you have a bike that fouls plugs easily, particularly with condensation, the pointy electodes of an irridium plug will still spark. My XV535 would get regular plugs wet with fuel and condensation in winter and then refuse to start. Started reliably on iridium.

denso ik22 works also, also an iridium tipped plug

I personally run NGK without any issues.

I've been pulling my CR8EIX iridium plugs out to check how they are burning a lot recently. I've been seeing some light ash deposits and high speed glazing and the iridium tips of the plugs are not as hot as I would expect them to be, i.e., they are not *white*.

I've been running these plugs for over a year and a half and hate em, I guess when I got them I wanted new fresh plugs for a hot climate but should have taken them out immediately as there was noticeable power loss. I'm looking to go back to stock now as the car really ran much better. This is an unmodded 08 gti.
