Are you running nitrous or FI ? if so you may want to use an NGK Tr6. If using the standard Tr55 I would say .55 to .60

I agree, naturally aspirated you should be at 55 or 60 thousands(TR55), forced induction or nitrous you should be gapped at 30 (TR6)thousands.

They come out of the box at about .55 I've found. I've tried lowering it to about .50 with my HC car and it doesn't seem to make any difference (good or bad). Just check em as you take them out of the box and throw them in, that'd be my best advice.
