This NCY Performance CDI works on most AC current GY6 50cc/150cc scooters made in China using the 139QMB/157QMJ enigine.

A billet aluminum case protects this from road debris. Confirm the connector design you have and that you have an AC ignition system.

The system voltage is raised up to 400-600 Volts by a transformer inside the CDI module.
