Using the Reverse Fitment Tool

Do you have spare parts in your garage, but aren't sure which of your vehicles they go to? Found an old spark plug in a barn? Use our reverse fitment tool to retrieve a list of applications the part fits.

To access the reverse fitment tool, simply enter the part number in the site search box. Let's use Champion H10C as our example:

After entering the part number, hit enter, or click directly on the matching result in the predictive search drop-down.

Reverse Fitment Part Search


Click on the "Fitment" drop-down to see a listing of the applications that may utilize the part.

Reverse Fitment Tab


For automotive results, find the year, make and model of the application you wish to confirm. Then click "Verify Fitment".

Verify Reverse Fitment


A part won't necessarily fit all sub-models, so select the appropriate application information from the pop-up box to confirm fitment for your exact model.
