Spark Plug advise Please? Alright, I need to do a tune up and replace my spark plugs. I have a 350 LT1, forged crank, Scat forged rods, forged pistons, CCAI, 52MM TB, Sweet Thunder 3" x 18" Chambered muffler. New Opti, 1.6 RR's, LS6 Lifters, Comp Cams push rods, LT4 valve springs, LT4 "Hotcam", MSD 6AL, MSD Blaster coil, MSD wires, currently using crappy oem replacement plugs. I am going to install a set of LT's and set up a true dual exhaust w/ x-pipe, and i got a steal of a deal on a NX Gemini Twin MAF system with 2 10lb bottles... I am probably gonna start small with a 75-100 shot. Also i am going to get my MADZ28 tuned pcm dyno tuned. I have used NGK TR55's before, and was thinking of ordering another set, but i also heard with nitrous you should have a step or two colder plugs. My question here is what spark plugs would you recommend? And how do i order plugs that are colder? Thanks.
