????????? OEM 7M calls out for .031" (zum close enough ;) ) Now as for increasing boost and such other supporting mods owners might gap them less so the spark dosent get blowen out and as gm said even a colder plug. But this can be trial and error on what gap works for you. I know a few members are gapped all the way down to .022"

Inclusion autozone is correct ;)
