I have seen dyno runs for the Denso Iridiums a multitude of times. Bottom line is they make more power even vs. brand new NGK plugs. Bottom line is they don't "make" more power, they just retrieve what power that your car has been missing.

The specific one that I am thinking of was a "back-to-back" run with a NGK vs. Denso plug change. Total time elapsed, 45 min, with three runs each to verify reliability. These were without correction factors.
I'm not trying to preach it, but I personally believe in them, just sharing my experience.
