thanks for the replies so far, im aware of the boosted engine gaps being lower but for a NA ~500hp or the average mild build of 300-400hp ive always heard .045 is the best general range & that a hotter/bigger spark was better most the time.
i do use the low resistance button in the cap for the super coil.
i have always set all my plugs to .045 maybe .048 due to a cheap gap gauge & never had any issues, but after reading that NGK FAQ i may try & lower it to .035. i wouldnt really consider the super coil or MSD module being "wizz bang" stuff, so maybe a little less gap is worth trying.
