Why Choose the GOOFIT GY6 Performance CDI?

• Enhanced Acceleration: Optimized ignition mapping eliminates "flat spots" in your engine's power band, providing a more linear and aggressive throttle response from a standstill.
• Stable Energy Discharge: Unlike standard units that fade at high temperatures, our CDI uses heat-resistant components to ensure a strong, consistent spark throughout long rides.
• Improved Fuel Efficiency: By ensuring a more complete fuel burn in the combustion chamber, this module helps you get more miles out of every tank while reducing exhaust emissions.
• Proven Reliability: Every unit undergoes strict quality testing to ensure the internal circuitry can handle the high-vibration environment of small-displacement engines, effectively reducing the risk of mid-ride breakdowns.
