◇ This is a replacement part of the highest quality. A vehicle knock sensor is a sensor screwed into the engine's block or cylinder head. It allows the engine to run with the ignition timing advanced as far as possible. The automobile's computer continues to advance the vehicle's timing until the knock sensor detects knock or detonation. After that the sensor sends the computer a signal to adjust the timing. This ensures greater FUEL ECONOMY and MORE POWER to get the most from your engine!

Our knock sensors are designed to respond to knock frequencies up to 1000 Hz accommodating shifts in engine knock frequency making it a more flexible sensor responding to correct engine knock over a broad range of vehicle conditions.

Manufacturing processes include an automated data acquisition system to continuously monitor the sensor output to ensure that it responds with appropriate voltage output at the specified frequency range All units are 100% tested using an accelerometer vibration test to ensure trouble-free operation.
