Warranty Disclaimer: Subaru of America will only warranty parts installed by a CERTIFIED Subaru Dealership. The part being installed must also match the vehicle VIN. IE If you install an STi block in a WRX at your friends shop, do not expect a warranty claim to come through if it explodes! Please use your best judgement.
