            A core is some portion of a part that can be recycled or reused by the manufacturer. This helps to reduce product cost and is good for our environment. For this reason a product with a core has an additional charge associated with it. If the old part is returned in reusable condition, the core charge will be refunded.

          • Photos or videos showing the defective part, order number, date, VIN, and odometer reading.

          • Diagnostic reports or part returns for non-visible issues may be requested.

          • Claims must be truthful, properly documented, and reflect normal consumer use.
