Champion Plugs?

No, you are describing Bosch Platinums. Those absolutely SUCK in a GM, but the parts stores really push them. People say I am a hoarder and I can honestly agree with them, but even I threw out a set of brand spankin new Bosch Platinums once... even though I've saved used plugs of other brands.

Never ran bosch, but champions are peices of ****. I dont even run them in my mower. My bikes and mower run NGK, and my monte and truck are ac-delco.
