Spark plugs and gap?

i am about to change plugs in my 00 lightning, mods include diablosport predator, 90mm mass air, k&n cold air intake, and a flowmaster dual exhaust kit, question is what plugs to buy and what the correct gap should be. and does anyone have a step by step process on how to cahnge plugs on a 00 lightning?

I did not see a pulley listed in with your mods, so I'll assume you're running stock boost levels. The factory platinum plugs or NGK TR6s work well for your application. Might want to gap them around .041 to reduce the chance of detonation.

When adding extra boost, the rule of thumb is to squeeze the gap down .001 for each pound of added boost. The stock plugs are gapped at .042, so if adding a 4 lb. pulley, you'd want to gap the plugs at a tight .038

According to that chart it says I should be gapping my plugs at .036. I have Denso's 22's and I gapped them at .032 that's with a port and a 6#er. If I gapped them at .036 I would be afraid of spark blow out.

If it idles and drives fine, then there is no need to open the gap.
