ok .. i just purchased NGK V-power R5671A-7 from murrays for my SR20det
i just asked for NGKs 7 for my SR and he gave me those.
would these work?i'm not even sure
mods: stock really .. just exhaust and FMIC.. running 7-8psi
as long as theyre regular.. platinum and iridium are ok i guess but they go bad really fast.. regular.. and just my $0.02, i use the lowest numbered one.. with the lowest heat rating or w/e.. just a tip i learned from some folks about boosted cars
You can get the same NGK N5671A-7 at any advance auto. They are $1.99 each. The stock number is 4091. They would probably have to order them for you but it should reach the same day if it's ordered early. Just set the gap and your good.
