Use the plain plugs. The only thing that will help a plugs performance is a larger or multiple path to fire on, IE split fires. Or a larger ignition box.
The different material plugs are made to last and not for performance.
If your ever at a drag race ask the big boys what their running. Most likely the plain ole' Autolites or equivlent.

Hello Frank,
That does make alot of sense........I've just seen so many ads for platinum and irriium, I thought I would ask people in the know.
Thanks,
