Use AC Spark plugs, but you'll get a selection of them at the auto parts store, ranging from standard AC Spark Plugs to the Platinum Tipped Spark Plugs.

Try the Platinum tipped ones to get up to 100,000 mi. per plug.

They are in the heads, sometimes they are hidden by a plate. Just follow the wires from the coil pack and it will lead you right to the plugs. It is always best to use manufacture's spark plugs. The universal aftermarkets are just not as good. You should use what is made for your specific car for best results. Probably AC Delco or BOSCH

Spark Plugs Manufacturer Specs

AC Delco is the only plugs I will sell to anyone with a newer style GM of any kind. I have sold "other" brands of plugs for them, but the customer always comes back complaining. I don't know why, but anything else will cause a miss. You can go ahaead and run something else if you really want to- but I warned you no matter what anyone else says.
