Universal Parts GY6 Performance CDI - AC

Unlock Your Engine: GY6 Unrestricted Performance CDI Eliminate the factory "bottleneck" and let your engine breathe with the Universal Parts Performance Racing CDI . Designed specifically for AC-fired GY6 50cc, 125cc, and 150cc engines, this unit does more than just remove the electronic rev limiter; it features a re-mapped ignition advance curve. This results in sharper throttle response, significantly improved acceleration, and a potential top-speed increase of 5–10 MPH on most stock and modified machines. Technical Performance Features Unrestricted Rev Limit: Removes the factory-set RPM ceiling, allowing your engine to reach its full power potential—essential for big-bore and high-cam builds. Optimized Advance Curve: Recalibrates the ignition timing to provide a hotter, more precise spark at higher RPMs for maximum combustion efficiency. "Gold" Series Housing: Housed in a durable, heat-dissipating aluminum case designed to withstand the vibration and thermal stress of high-performance riding. Plug-and-Play Reliability: Features the standard 6-pin (4+2) rounded male plug configuration for an instant, tool-free installation on most Chinese-style wiring harnesses.
