Walker Products Knock Sensors (KS) are precision manufactured from premium components in an ISO 9001-2008/TS16949 certified facility. The knock sensor detects vibrations in the engine caused by poor quality/low octane fuel, increased cylinder pressure/heat or over advanced ignition timing. The knock sensor alerts the onboard computer of the vibration and the computer uses this data to retard ignition timing.

Walker Knock Sensors are designed to provide outstanding performance and are manufactured to meet and exceed all OEM (Original Equipment Manufacturer) specifications and test requirements. Walker Products specializes in the engineering, manufacturing, and distribution of automotive engine management components. Trust their award winning commitment to product quality when replacing the knock sensor in your car, truck, van, Jeep, CUV (Crossover Utility Vehicle) or SUV (Sport Utility Vehicle).
