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.
