Genuine Kia Knock Sensor

When fuel is improperly ignited, it creates an irregular combustion that can interfere with the normal cycles of the engine and can even damage its internal components. To prevent this, a Kia knock sensor is installed, a piezo-electric component designed to allow the engine to run with ignition timing as far ahead as possible. When the knock sensor detects a sudden spike in pressure in the cylinder walls, its sends a signal to the engine control module to adjust the ignition timing accordingly.
