Features: It is the programmable universal sensor specially built for efficient sensor replacement. It perform like old sensors,in terms of signal interval,durability,and functionality. Featuring-a convenient design that allows for quick installation and removal of the sensor,it is truly the-ultimate TPMS solution. Sensor is a programmable universal sensor specially built to combine both. 315MHz and 433MHz applications in one-sensor for efficient replacement. Featuring-the exclusive press release valve-design to allow rubber and metal stems to interchange by hand,without a sensor head fitting tool. Performs like sensor signal interval,durability,and functionality. Sensor can replace direct TPMS sensors fitted on-wheels, including old equipment and programmable universal sensors. Universal 433MHz 315MHz Metal Stem Sensors offer the latest model vehicle coverage because these TPMS sensors quickly update during installation with an wireless programming tool.
