Hi all

i checked my spark plugs, and everyone looks nice brownish-or something in that way) except one, that was snow white...

dumb question: can this be a vacuum leak in the junction manifold/head or is this rather a not so good injector? (i tend rather to believe the second)

my intake is a single plane EFI manifold (maybe considering swapping to an modified stealth ram), heads are 210cc AFR

i got the Felpro 1206 with them

regards
