Brand and material notes
Copper plugs are often the least expensive. Platinum and iridium listings usually last longer and cost more. Use the merchant page and your owner’s manual — this site does not assign a heat range or claim a performance gain.
Before you buy
- Confirm the engine code on the vehicle or build sticker.
- Match the OE spark-plug number when you have it.
- Check plug gap, torque, and how many plugs the engine uses.
- Treat Advance and Amazon cards as separate offers, not the same SKU.
Other eligible years
This site contains affiliate links. We may earn a commission if you buy through Advance Auto Parts or Amazon. Listings come from merchant catalogs for the selected year, make, and model. They are not OEM confirmation of engine, plug gap, torque, heat range, or quantity.
