I guess I could try a set and see. Almost did the other day until I saw the prices. LOL
Reading the stuff above, I did have fouling issues running race plugs like the Autolite non resistor type AR3933. Ran ok (not better or faster) when first installed but the next couple drives really sufffered. Put back in the typical copper projected tip resistor types and runs perfect but I'm worried about the tips breaking off during a full pass...
