Im just curious what you track oriented guys run as far as spark plugs and gaps. Im currently running Autolite Double Platinums (APP25s) in my Edelbrock RPMS. I think they are gaped at .040 or .045 I cant remember.

Im curious about the new ZEX plugs as well as the Autolite Racings, and hell anyone using NGK Iridiums?

IIRC, I'm using the Bosch's Roadracer refers to.

Flawless performance and their construction is impeccable...

I thought most of the aluminum heads were using Autolite or 3923 or 3924 not the 25's. Also AR3923 with cutback electrode .
