stick with AC delco that comes with the car.i have yet to see a spark plug perform any better and last as long than an AC delco in a GM car. dont take this as a shot to imports but when it comes to GM cars they dont like anything but AC Delco.even the super expensive Bosch dont play nice with GM engines.
