Devices that capture knocks vibration in the engine and transform them into an electrical signal. The knock sensor supplies a response signal which is used to control the advance of ignition timing, assisting in the improvement of the performance of the engine and in the fuel saving.

CARE DURING INSTALLATION
The contact surfaces between the sensor and the engine block should be free of any kind of imperfections.

Torque : 2.0 ~ 2.5 (Kgf.m)

Its torque must be correct, therefore the lack or excess of torque modifies the sensor reply.

If it does not have to use washers between the sensor and the block of the engine and/or headstock.
