im in the middle of doing a tune up on my car i was told to gap the plugs at .042 i have stage 2 i was just gonna use the stock gap i have ngk g power plugs what do you guys recommend for a gap?

 

i gapped mine at .038 and it ran ok but after a while i needed new plugs anyway cuz i use the copper autolites. when i got new pugs i gapped them at .032 and it runs much much better now

 

so what is stock? my buddy swears up and down its .042 i just dont want a shitty gap and get like misfires

 

your buddy is right that the stock gap is .042, however when you upgrade your pulley you want a smaller gap. i am complete stock and gapped mine at .035. and it runs fine no missfires as of yet, gonna change em in about 800 miles tho with my oil. i think .038 is a good safe number.

 

I believe misfires come from a larger gap, too much fuel and no spark occurs. Smaller gap less likley for a misfire but the spark is not as large so not all the fuel will be burned and your leaving behind some power. Gotta find a happy medium for your car.

.038 seems to be good for me.....

 

alright so im gonna go finish up and gap them to .038...now we r gonna start brakes im sure ill have more questions half way threw thanks dudes

 

I've had my plugs gapped at 0.035 since day one. The car runs great !!

 

i run 0.035.
