I have some spark plugs that I tried to do this before with but never got back any results from the people I sent them to. Looking to see if gas mileage improves with a set of WeaponX iridiums.
Dyno testing show a gain in the mid range of 5-8hp. Theoretically this should produce better gas mileage. I'm looking to prove it one way or the other. I need a car that runs good and gets the same mileage all the time. We'll swap plugs and see what you get. The we'll swap in a new set of NGK's and see what you get and lay this to rest.

Does a slight gain in the mid range actually translate to improved gas mileage ?
