Is anybody running the Denso plugs that Mike sells in a V6? Are they worth the money and do they make a difference? I've got almost 50K on my 4.2 and figure it's time for plugs. I've got most every other bolt on mod with the exception of the throttle body spacer

Thanks,

Mitch

 

I installed the NGK Irduim plugs in my 2000 supercab with Accel 9000 wires at 30k. I couldn't honestily say I could tell a difference. The Motorcraft plugs looked fine when I took them out, I sure wasn't going to wait 100k. I also have about every bolt on except headers and I guess if they did give 2 or 3 hp it would be hard to tell. The Accel wires had about half the resistance of the Motorcraft wires by my ohm meter.
