Alright, one of my friends bought some spark plugs with the 4 prongs on it. I told him he was an idiot and he asked why. For those who dont know, a spark jumps from the base of the plug to the prong. having 4 prongs does NOTHING. The only thing it is good for, is if the resistance on one prong gets too high, the spark will start jumping to another prong. So, i would not recommend anyone buying spark plugs with more than one prong. Hope this helps out some people who buy the expensive 3 or 4 pronged ones.

I see the only real benefit in having mroe than one prong is , like you said, if one becomes too hihg of resistance. i usually get the two pronged ones, just because I like the idea of a sort of backup plan. but wasting money on the quads is not really a good investment if you take care of your fuel system.

Speaking of fuel system, what do you all do to keep your injectors clean? I heard buying those additives for your fuel is a bad thing, but i also heard that taking to get them serviced on those machines is $$. And, for the stock injectors, since they blow at 230hp (saw on another thread), do they make better ones?
