I have a 20g EVO 9 Turbo, HKS 264e/272i cams, 660cc injectors, TBE, HKS RS, Greddy TYPE S BOV, Weisco Pistons, eagle Rods, ARP main and head studs, MR Exhaust manifold, and Greddy V-Spec Intercooler. I wanted to know what spark plugs should I use with this setup and what should I gap it to?

No problem.What boost are you running? Also buy an extra set of plugs and keep them in the trunk (along with the tools to remove them).

 

I am running about 21.5 lbs right now.
