Don't let a failing camshaft position sensor rob your vehicle of power or cut your track day short. This Meyle replacement camshaft sensor is built to deliver fast, highly accurate data to the ECU, preventing the performance drops, sluggish throttle response, and rough idling caused by worn-out factory electronics. Engineered to withstand high underhood heat and intense vibrations, it keeps your ignition timing and fuel delivery tightly synced, whether you are daily driving or pushing through high-RPM pulls.
