sup every1 im gettin the juice so i need a part number for plugs..i have trick flow twisted wedge so i think i need autolites....and what gap should i used im running a smalkl shot(50) then go to 75 eventually...and is 12 degrees timing ok??..thanks
autolite copper 25s are fine. just make the gap a little smaller so the spark wont be blown out. Around .035" should be fine. And what timing do you run regularly? If you regularly run 12 degrees, you should back it off to 10* for the first time and run 92 octane. Then experiment w/ timing from there.
ok thanx i am running 14 degrees timing and was planning on running 12 with a 50 and 75 shot...have a h/c/i combo that puts down 300 rwhp untuned and before my injectors that was when car was running a lttle lean so thats y i am goin easy on the juice no more then 75 i donmt wanna kill the tranny....so im not even juicing it off the line once i get into 3rd ill hit it....so whats the part number for the plugs for aluminum heads?
