4 Pin DC CDI Ignition Module for 50cc-125cc ATV Dirt Bike Go Kart

Product Overview

This 4-pin DC CDI ignition module is designed as a replacement ignition control unit for many 50cc, 70cc, 90cc, 110cc, and 125cc ATV, quad, dirt bike, pit bike, go kart, and mini bike engines.

The CDI module helps control ignition timing and deliver a stable spark signal to the engine. If your vehicle has hard starting, weak spark, misfiring, poor acceleration, or intermittent ignition failure, replacing a worn or faulty CDI may help restore smoother engine performance.

Built with reliable electronic components and a compact sealed housing, this replacement DC CDI is made for everyday riding, off-road use, and small engine powersports applications. Please compare the plug shape, pin count, CDI type, and size with your original part before ordering.
