Default Re: Spark plugs, spark plugs, spark plugs...

If you have your owner's manual, plug brand and model should be listed. Online GM owners manuals are available by searching for GMs site. Other alternatives are calling your local GM dealer if they're willing to spend time to answer your query or searching online. Most online parts distributors will list several plugs and may highlight the oem part and number. Larger sites like rockauto do the same and will list the oem part.
