I have a lot better mileage then I did with my OEM plugs. the copper need to be changed more often then the platinum plugs. very much better spark. so with the better gas millage and hotter plug I like that. for the cost I am very good with that. I have gone from 29 mpg average to 32 mpg average with the change in plugs.
