Match the numbers to your setup

The specs above are the fastest way to confirm a part is right before checkout — a size or power rating just outside your factory setup usually means an adapter or a different SKU, not a return later. If you are not sure which spec matters for your vehicle, the fit tool at the top of the page narrows the catalog to parts already confirmed for your year, make, and model.
