My COPPER plugs (NGK BKR7E) are gapped at 0.032" per JoeP recommendation.

I got mine put in today, so hopefully I can run a little higher boost w/o detonation...

I've had mine in for about 2 weeks now, running 11-12psi daily, no detonation and not a single problem, just fun!

Thats good to hear..you're using the NGK copper plugs right? Also, are u using a MBC or EBC?

Copper yes, and the MBC. All is working good so far, I do check everything though, all hoses and oil and watch my gauges closely, but all seems well. I want to get an EBC but that'll have to wait a little while, I want the HKS EVC II I think it's called, with the add-on LCD screen.

NGK is in the the process of releasing a new Iridium plug

BRK7EIX (no 11) This plug can be gapped differently.

The BRK7EIX-11 is really not supposed to be gapped any lower than .036. So if you have purchased these and are gapping to .032 or .030. The plug is not firing to it's fullest capabilities.

Just a note....
