Knock sensor — original OEM part 55563372 Opel 1.4

Original knock sensor for 1.4 petrol engines in the Opel group. It detects uncontrolled combustion and allows the control unit to adjust the ignition timing — protecting the engine from damage. A faulty sensor causes a loss of power, increased fuel consumption, and an ignition system error. Part removed from a non-accidental Opel Meriva, fully functional.

Part number (OEM): 55563372.

Fits, among others: Opel group cars with 1.4 petrol engines — including Meriva, Astra, Corsa, Insignia, and Mokka — equipped with a sensor bearing this part number.

Condition: used, fully functional.

Before purchasing, compare the part number with the sensor removed from your car — this guarantees compatibility.
