What sends people here

Misfires under load, rough idle, or a drop in fuel economy. On a full-size van, GVWR rating and upfit configuration split this group.

What you get ordering from us

• Factory sourced. These spark plugs are built to GM's own drawing by the supplier GM contracted.
• No guessing. Our VIN lookup resolves the near-identical spark plugs numbers for you.
• Ships from Dallas. Spark Plugs ordered by 3pm Central go out the same business day.
• Straightforward returns. No restocking games on spark plugs that did not fit.

Before you order

Aftermarket versions are often close enough to install and far enough off to cause a repeat repair. Option packages divide this catalog more than model years do. Send the VIN and skip the problem. Our Dallas location means most of the country is inside a two or three day ground window.
