In my opinion Autolite makes some of the best 'normal' platinum and copper plugs.

 

I have the Bosch Platinum 4's and my car seems to fire up a little quicker when it was cold. I couldn't say I noticed a change in performace.. I kind of agree that the spark and really only use one electrode at a time. However.. I race motocross, and ride a CR250, and I've really had good luck with splitfire, they seem to perform better, and are much less prone to fouling while woods riding.. I know alot of ppl bad mouth them.. but I've had good luck.. my two cents..
