02 Fitment

  1. Spark plug heat range and gap are set by the engine maker. Use the plug listed for your engine, not a near match.
  2. On coil-on-plug engines a misfire code names the cylinder, which tells you which coil or plug to check first.
  3. Choose your vehicle on the part lookup first, so the retailer searches below include it.

Coming soon

Vehicle-by-vehicle fitment for spark plugs is added only where we can cite a source. Vehicle pages already cover the best-selling models.

03 Cross-reference

Coming soon

Interchange numbers for spark plugs show here once we have a source we can cite. Until then, enter your VIN in the factory parts catalog to get the original-equipment number, and compare that number across stores.
