Iridiums are supposed to have lower misfire rates & last longer. But they also foul more easily. I run the reg TR-6s.

Why would they foul eazy?
do they run to cold?

i was told that irridium tipped plugs with forced induction are a NO-NO. something about the tip staying hot and causing detonation

I think one of the contributing factors in the plugs fouling is the richer A/F mix that you normally run in forced induction. At $7 a plug I don't think the Iridiums are that much better.

I would (and do) run Denso Iridiums in my N/A car.
