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.
This will not work with a 1952 Nash Rambler. Nor will it fit a 150cc Wolf Jet II. The Jet II is a DC system.
