Copper!
What kind of boost pressures does your system normally see? A stronger spark via thicker wires/lower resistance & MSD may be a consideration. But maybe not.. More than likely not.

Maybe its my use of E85 but the copper plugs would foul at 15psi of boost within minutes. Switched to Champion Iridiums and the problem has gone bye bye. smile.gif
