I was told Copper NGK 4177 on the ModularFords Kenne Bell forum. That's what I put in but I've yet to fire up the car. I'm still not done with my install.

Denso Iridiums

Denso Iridiums

This is also what I was told after mentioning the original suggested plugs, "Avoid the Iridium plugs as they have high resistance to spark under boost."

This is all "hear-say".

Anyone else want to chime in?

I have used Denso's in my 01 GT w/Saleen seires IV sc & in the cobra for 3 years, I change plugs yearly. I have never had an issue with them. You need to make sure you have the right heat range and they are gapped the right way.
