Cross-referenced parts are cataloged as fitting the same application but are not guaranteed to be identical to the original manufacturer part. Verify fitment against your OE number or VIN before ordering.
Compare your original OE number against the OE Reference Numbers listed above, and check the dimensions or specifications against your original part.
OE parts match the original manufacturer specification. Aftermarket parts are cross-referenced to fit the same application, usually at a lower price.
