Schrader is the leading global manufacturer of tire pressure monitoring systems (TPMS) and its direct OE TPMS technology can be found in over 50% of vehicles globally. Matching OE quality and performance standards, Schrader sensors go through extensive OE quality testing, including high speed and extreme temperature tests. Schrader's global presence as the leading OE supplier means that OE quality and performance come standard with Schrader's genuine OE replacement sensors. Schrader's PN 20281 OE Replacement Rubber Snap-in TPMS sensor with 433 MHz is a direct replacement and comes pre-programmed to the specific makes, models, and years of the multiple Hyundai and Kia vehicles. A vehicle-specific relearn procedure must be performed after the sensor is installed, often requiring a TPMS programming and diagnostic tool with OBD capability. TPMS sensor is not a DIY product and requires appropriate skills, knowledge, and equipment for service.
