        This warranty is valid for the stated period of time printed on your Invoice and Order Confirmation email provided you were the original purchaser of the part and you still own the vehicle on which it was installed. This warranty cannot be transferred to anyone at any time. Parts installed on commercial use vehicles are warranted for 90 days from the date of purchase.
