I have denso iridium spark plugs in my engine, but to be honnest i didnt run the car with the standard plugs before, so I wouldnt know what the difference is.

Actually tell a lie, I have just looked at the old ones, they were in before the car was mapped, and it was only doing 12mpg then! I put the new ones in the day I took it to Steve Grinnald - DTA mapping Guru.

As long as the plug is of the right heat range and working correctly then there should be no power to gain. New plug technology is more to do with service intervals
