UPDATE. The internal batteries of these sensors failed after 18 months of installation. Not sure if it was the old batch. They worked well if they lasted long but are not OEM reliable for battery life. ** This is a great replacement for Subaru OEM TPMS sensors. However, these particular sensors are not programmable like some of the newer Orange TPMS sensors and lack the OPSS markings. If you just want a replacement for a broken OEM sensor they are great and fantastically priced. You just need to reset the TPMS module in the car to relearn the new replacement sensor ID. If you're looking for a second set of sensors, you can clone your existing sensor IDs into a second set of snow tires so you can swap back and forth without having to reset the car's TPMS module every time you change wheels. Look for those who are orange OPSS. OPSS sensors are fully programmable with the Orange T30 programming tool.
