4PCS Tire Pressure Monitoring Sensor 39186445 433MHz TPMS for Opel Astra K, Insignia B | Vauxhall Compatible

Keep your tires at the right pressure with this set of four TPMS sensors. Designed for specific Opel and Vauxhall models, these 433MHz sensors replace part number 39186445. They come pre-programmed, so no extra setup is needed before installation.

This TPMS sensor set helps you monitor tire pressure in real time. Accurate readings let you spot slow leaks or pressure drops early, which can improve fuel economy and extend tire life. Each sensor is built to last, with a battery life of about three years.

The sensors are a direct replacement for your original equipment. They fit the valve stem and communicate wirelessly with your car’s onboard system. Once installed and activated, they send pressure data directly to your dashboard display.

Installation is straightforward for a trained professional. The sensors are already programmed for your vehicle, so you only need to mount them and complete a re-learning procedure with a compatible scan tool. This saves time and ensures a proper fit.
