autolite 104 gapped at .055

with the cam you could probably run 103's with a gap of .055 to .058

it depends on the car..everyones car is different.
got to try em..run a little then see how the cars running...swap em out and try new ones. with plugs its alot of trial and error.

Ive ran delco 932's, autolite 103 and 104's the 932's seemed to be the best for my car even though there platinum and cost 6 bucks a peice compaired to the autolites that are a buck a piece.

Currently im running 104's at .057 and im a little rich..might change the gap a little or just drop back to the 103's.

which way would you want to adjust the gap to make it not so rich? more or less gap in the plug?

ive never heard gap affecting O2s, or plugs for that matter.

depending on how much boost your pushing.

605s 1 range colder
104=2 steps colder
103=3 steps colder


noway are you ready for 103's..imho

Intenses web site will give you a better understanding which plug to use.

I push 8-13 LBs of boost depending on pulley.
103s made my car run like crap, so ive been using 104s and the car runs real good. gapped at 50, right now, as of yesterdays plug swap.
