spark plug question?
Has anyone ever used the diamondfire e3 spark plug. I want to go ahead and replace my plugs. i have always just used NKG but i figured i would see if theres were any better. the only thing is i have heard that if you use the plugs you need to use the dimond fire e3 spark plug wires. of course that would be a problem due to the COP. any ideas or sudgestions?

I've always felt that the "super advanced" spark plugs were a little on the snake oil side. I'd stick with Motorcraft and save the cash personally.
