The warranty period is 90 DAYS from your date of purchase. During the warranty period, we will replace or refund, at our option, any new part that fails due to a defect in materials or workmanship under normal use and service after proper installation. Simply return the part along with your original sales receipt to OEM Marketplace. You must be the original purchaser of the part and still own the vehicle on which it was installed. This warranty is not transferable.  OEM Marketplace is not responsible for any labor associated with replacement.
