I'd use NGK BPR6es. Mostly stock car=stock plugs.

I'm running NGK irrdiums. Not sure of the part # off the top of my head. Here's a small list of aftermarket parts I have installed. Dejon tool cold air intake with K@N filter, Cat delete, Compitition spark plug wires, as well as a 1997 4G63T engine. I'm running just fine. But I've been using 93 octane from my local Shell. I've attempted to locate some Nippon Denso spark plugs, but have been unsucessful in my area.

I have talked with many guys who have built boosted applications for years and most of them say that if you are working on the car yourself then use copper plugs. I know this sounds really dumb right?? There is a method to the madness. A copper plug is a failsafe. If you are working on your car and it ends up running to lean then it is easy to mess up a motor quickly! Now if you ran it lean with a copper plug then you will just melt the plug down and lose spark before you do any serious motor damage.

I personally run NGK BPR6ES but will be switching to a colder plug once i put my 550s back in and turn it back up to 20psi.
