HMParts AC CDI Ignition Unit For 250cc 2-Cylinder ATV/Quad Engines | China Quad

This is a new AC CDI (Capacitor Discharge Ignition) unit from HMParts, specifically designed for 250cc ATV and quad bikes with two-cylinder engines.

If your Chinese-made quad is having trouble starting, misfiring, or just not running right, a faulty CDI box is a common culprit.

This is a direct replacement for the stock ignition control module, getting your engine's spark back in sync.

It's a crucial part of the electrical system that manages the ignition timing.

This one is made for the job, so you can swap it out and hopefully get back to riding without any more fuss.

Made in China and built to get your 250cc machine firing on all cylinders.
