checkers told 0.0375 with champion plugs thats why i was asking. i had 15000 on this park plugs took them off and the gaping was 0.055 so i re-gapped them to .035. motor seems lighter and mpg are going up but not by much


thanks for the replies it did answer my question

i will check my hood for that info

I would gap them to .040 gap. This is what I set all the 4.7L plugs to.... the 3.7L uses the same coil packs and is basically the same engine as the 4.7L with two less cyliders.
