June 15, 2010i had some and took a chance on them. suck! they did fine at first, sort of. i would be going up a hill and the truck would start lunging. then it progressed to just passing. jerk really bad.never had lights come on, but when i got my custom tune, my guy had his computer hooked up and the truck was missing a lot. changed to ngk irridums. no more problems. ac delco or nkg.........save your self some cash.
