A failed Knock Sensor will often have no noticeable symptoms beyond a check engine light or engine ping or knock, but it does cause your Subaru to operate inefficiently and produce higher emissions.
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.
