Important fitment notice. A saved mapping narrows the search; it is not a guarantee of fit. Fitment can vary by trim, engine, body style, production date, factory equipment, and vehicle modifications. Before ordering or installation, verify the part number and specifications against the owner’s manual, the original part, VIN-specific manufacturer information, and the seller’s current compatibility details.

WHAT TO VERIFY
Spark Plugs fitment starts with the exact vehicle.
Spark plugs must match the exact engine. Do not infer compatibility from thread diameter alone, and do not assume a listing contains enough plugs for the entire engine.
- Exact engine and plug number
- Heat range, reach, seat, and gap
- Required quantity and torque procedure
