Autolites, 1 heat range colder than stock. I don't remember the part number off hand though. I think I gapped mine at .35
EDIT: I'm running Autolite 3923's

What to run a plug that will resist spark blowout and run super cold? Try an Autolite 404, gapped at .038~ I ran these in my combo for over a year, they work GREAT. ![[Cool]](cool.gif)

No platinum! Don't run platinums with a supercharger! I run the Autolite copper resitor plug 3922, most run the 3923 gapped at (.035).

autolite racing plugs gapped at .030 is what I would start with. JMO try a heat range colder
