This NCY performance scooter CDI igniter module works on most current AC GY6 50cc/150cc scooters made in China using the 139QMB/157QMJ engine. Higher voltage output, aggressive mapping, as well as the removal of your rev limiter make this ideal for custom builds, or just simply trying to get a few more MPH's. A billet aluminum case protects this from road debris. The system voltage is raised up to 400-600 Volts by a transformer inside the scooter CDI module.
NOTE: This part is for off-road use only and carries NO WARRANTY.
USE AT YOUR OWN RISK. Please be sure to confirm the connector design will match, and that you have an AC ignition system before ordering.
