Yeah I was just about to ask this and searched. Gmparts direct list stock plugs as 5.37 each and rockauto.com says bosch double paltinum plugs are OEM at like 8 bucks each. I think ill be going with NGK's or either Denso both iridium and double platinum or whatever.NGK's are like 6.70 and Densos are like 4.70 each. Idk but i can feel a little miss/hesitation under throttle and mpg's are starting to drop a bit so its time for plugs....and i guess i could do wires as well.
