How long ago did you change them?
Are you the one who took the iridiums out and put in OEM coppers? If so, did you gap them using a quality tool?

I used the ngk 1X iridium with my 2006 3.7l with 54k. Mpg went from 11.7 to 12.9. Not a huge diff, but on these busy, stop and go streets, any increase is better than none. Reset both computer and the mpg readout.

Well, at 15,000 miles a year and 4.15 gas, you saved 494 dollars /year. Not too shabby.
