6-Pin AC CDI for 50cc-125cc
Restore your engine's heart with the Universal Parts 6-Pin AC CDI. As the primary controller for your vehicle's spark and timing, this Capacitive Discharge Ignition (CDI) unit is engineered to deliver a consistent, high-energy pulse to your ignition coil.

Technical Performance Features
- AC-Powered Reliability: Optimized for standard stator-fired ignition systems, ensuring dependable starting even with a low battery.
- OEM 6-Pin Configuration: Features the industry-standard "2/4 Split" connector (two plugs: one 2-pin and one 4-pin) for a secure, click-in installation.
- Heavy-Duty Resin Casting: The internal circuitry is fully potted in a vibration-resistant resin to protect against the high-impact conditions of off-road riding.
- High-RPM Timing Curve: Calibrated to provide stable timing across the entire powerband, from idle to wide-open throttle.

Mechanic's Note: CDIs are often the silent cause of a "no-spark" condition. Critical Tip: Verify your system is AC-powered before ordering. If your headlight only turns on when the engine is running, you likely have an AC system. Installation Tip: Ensure your Stator and Ignition Coil grounds are clean of rust, as a bad ground is the #1 cause of "blown" CDI units!
