RE: ngk

what are your mods? the more boost you run the lower gap you should go. i'm running .035 right now, and will probably lower it a little soon. bone stock .045 is good, .040 for basic bolt on stuff (s1, etc.).

RE: ngk

.035 or .040 would probably be best. try both and see which one the car feels better with and go with that.
