450 hrs on iridium plugs.......
my plugs show no wear at this time. i am planning on getting 2,000 hrs from them. they should pay for themselves by then. running slick mags anything that may help increase the spark is a plus. also they may be more reliable that standerd plugs which i had one go bad on first engine run of 3,150 hrs. overall it fells good that i am running a better plug. turbo
