The THUNDERMAX Replacement Oxygen Sensor 309-355 is designed for use with the ThunderMax ECM auto-tune system. This replacement sensor supports the system's oxygen-sensing functionality for compatible motorcycle applications.
Installation involves replacing the factory ECM, installing new oxygen sensors and the harness, and loading the correct map for the motorcycle. Because clearance issues may occur, some aftermarket exhaust systems may require modification or relocation of their oxygen sensor port bungs.
