Re: E3 Spark Plugs Diamond Fire - Spark Plug
I replaced my NGK IX's with the E3s... They are good. I can slowly rev up to redline with no hesitation at all now. I also replaced my wires and got a screamin' demon coil all at once with the plugs, so I'm not sure if the E3s are better than the NGKs, or whether it was just the full tune-up that did it. But I will tell you that they really do work.
