NOTE: The EN 47833 must be installed to the supercharger in order to prevent damage to the supercharger bypass actuator cable and the finish of the supercharger. Failure to use the EN 47833 can lead to bending the brackets of the supercharger bypass actuator cable. Bent supercharger bypass actuator cable brackets will cause the supercharger bypass valve to function improperly.
