Manufacturer's Warranty — APR

APR warrants its products to be free from defects in materials and workmanship prior to installation.

Not covered: labor; misuse or abuse; improper installation; failure of related or connected components; and any product not purchased from APR or an authorized dealer. Grey-market purchases are not supported — claims on product bought outside authorized distribution are declined. Claims are made through APR or the authorized dealer or reseller you purchased from, so if you bought it here, contact PitStopTuning and we'll file the claim with APR for you.
