Lugging is bad bad bad for any engine.

I tried the Brisk plugs from Alta --- terrible performance! Didn't try different gaps tho, as suggested above. Maybe next time I change plugs, I'll try various gaps with the Brisks (I kept them). Had best results replacing the OEM version. Had lotsa trouble finding them. None of the other local auto parts houses had them available. Last Fall, NAPA had one full set available on the west coast --- I got it! Didn't try the dealer.
