well i bought stock GTE plugs because i was sick of my crappy idle and missing with the NGK's. well i didnt gap them when i put them in, the gap was huge but somone told me not to gap them so i didnt. so now im getting break up at full boost. should i just gap them as i would the NGK's?. i barley get any break up and i think they are pregapped to .040 or so. i m thinking of dropping it down to
.030.

the only plugs not to gap are iridiums because of thier tiny tips.

All other plugs, gap em!
