Iridium spark plugs, which ones?

[V6UnderPressure]

Want to get a set for my GN, I am looking for recommendations. MY GN will be street driven mostly on 93 octane. a couple trips to the track for race gas but thats it. I am running a PT52 with msd 50's, accel dfi, powerplate, atr headers, atr downpipe, atr hp116d exhaust, stock intercooler with duttweiler neck, big mouth cold air kit, precision 70mm plenum & 70mm accufab TB. etc etc. Anyone have any ideas and part numbers.

I have been wanting to find out more about iridium plugs, since I heard about the Denso's.
Dutwiller had very good luck using them in a Ford.
I understand NGK also makes them.
At $12 each, I'm reluctant to experiment.

Look on ebay and you can find a decent amount of NGK's for half that. But I would like a specific part number to use. I know with the amount of boost, I would need a colder plug. And I read someone else using them here but cant remember who. Maybe they will chime in.

Ur5IX is the part number for the NGK plugs. Comparable to the cr 43 AC Delco. They were 5.00 bucks a plug at Bumper to bumper.
