    The Denso's are a little cooler plug so they say they work with when mod's are done too.I run the Denso's in both of mine.

    Do the nipon denso plugs give you a higher rpm? I just swapped my plugs to the ND and I now hit 8100 rpms consistantly as opposed to 8000rpms. Do you tighten down a 1/4 or 1/2 turn. I didn't want to torque em down so I only went 1/4 seemed pretty snug. When I went to take the old plugs out I had to give it a little muscle to break it loose and ended up scratching the engine.

    I thought what the hell are those little marks I don't remember seeing them before..........Damn it!
