Iridium NGKs gapped at .033
I know what you're thinking... but they worked flawlessly with the stock turbo all the way up to 21 psi.
Richened it up to 11-12 AFR... same thing.
And I have too much 93 in the tank now for it to be worth putting 94 in. (Plus it's damn near $4/gal for 93 already.) :-/
Any other suggestions?
