I'm at 40,000 on the stock plugs. I pulled them not too long ago and they looked perfect.

Mine are gapped at .024 since I run 30 psi sometimes on race gas, and don't want to change the gap from .026ish to .024 everytime I up the boost, so I just leave it at .024.

I went to 45K, I believe the manual calls for it at 60K. They were fine, could have done another 15K.

Iridium is one of the hardest elements on earth, that ish can take a ton of heat and abuse.
