CDI Box 12V 4-Pin DC for 50cc, 70cc, 90cc, 110cc, 125cc ATV, Dirt Bike & Go Kart

GOOFIT High-Performance 4-Pin DC CDI Box – Digital Ignition Module

Unlock the full potential of your small-displacement engine. The GOOFIT 4-Pin DC CDI Box is a premium ignition solution specifically designed for 50cc to 125cc horizontal engines. By optimizing ignition timing and spark intensity, this module provides smoother acceleration and a noticeable increase in engine responsiveness. Whether you are navigating a trail on a dirt bike or working on the farm with a quad, this CDI ensures your engine fires with precision every time.

Constructed for the rigors of off-road use, the vibration-resistant and waterproof housing protects the sensitive internal electronics from the mud, dust, and moisture common in harsh riding environments.

Product Compatibility

This 4-pin DC-powered module is a universal replacement for many Chinese-manufactured off-road vehicles:

How the Ignition Process Works:

The GOOFIT CDI acts as the brain of your ignition system. High-voltage electricity generated by the coil is managed by the Electronic Igniter (CDI), which then pulses the high-voltage package (Ignition Coil). This energy is transferred through the spark plug to complete the combustion process with surgical timing, resulting in a cleaner burn and more horsepower.

Why Choose the GOOFIT 4-Pin DC CDI?

• Optimized Ignition Curve: Tuned to eliminate "flat spots" in your acceleration, providing a more linear power delivery and improved throttle response.
• Superior Spark Intensity: Delivers a stronger, more consistent spark than standard factory modules, which helps with cold starts and engine stability at high RPMs.
• Rugged All-Weather Build: The housing is specifically engineered to withstand the extreme impacts and temperature fluctuations of trail riding, significantly extending the service life of your electrical system.
• Easy Plug-and-Play Install: Designed to match the standard 4-pin harness found on most 110cc and 125cc machines, allowing for a 5-minute replacement with no special tools required.
