The 1-Sensor combines both 315MHz + 433MHz frequencies into one TPMS sensor with the highest industry vehicle coverage. The exclusive MX-Sensor patented PRESS release valve stem design, allows rubber and metal valve stems to freely interchange by hand, without requiring a tool for sensor head fitting. Built to match or exceed OEM sensors in frequency strength and durability, MX-Sensors are 100% ID clone-able with no relearn required and offer latest model vehicle coverage because they quickly update during installation with an Autel wireless programming tool.
