Hi Gordon!

I have a HO 302 EFI with GT-40P heads. I'm installing a Paxton 5-6psi supecharger. I want to make sure I'm doing what i can prior to running the dyno. Currently I have Champion 4013 plugs with a gap of 0.054. Should I run a colder plug with a gap around 0.035? Any suggestions on plugs?

Thanks for your help.
