spark plugs are pretty much just a dumb end of a wire sparkmaker thing, one's about as good as another. all these iridium, neodynium high pluton quattrio electrodic capacitor emittitron stoggnitonic altruisticon element sorta plugs are pure marketing bravado. you might get 1/4 more hp. at 8,000 rpm with some fancy plugs. that said, it's more about the energy going to the plug than the plug itself.
