Revitalize your engine timing with a direct, reliable replacement

The IFATRUNK Crankshaft Position Sensor is engineered to provide real-time crankshaft angle data to your vehicle’s ECU. Built as a direct replacement, this sensor aims to offer a straightforward, plug-and-play swap that fits without guesswork or modification. By restoring accurate timing information, it helps your engine reference piston position more consistently during startup and running, supporting smoother operation and better drive feel.
