Protect your engine with SensorGal’s Knock Sensors. These sensors detect abnormal combustion (engine knocking) and alert the ECU to adjust ignition timing, preventing damage and ensuring smooth performance.

A failing knock sensor can cause poor acceleration, increased fuel use, warning lights, or engine noise. Replacing it with an OEM-fit knock sensor restores performance and efficiency.
