Quadboss CDI Box

The Quadboss CDI Box is a high-performance replacement ignition control module (capacitor discharge ignition unit) for ATVs and UTVs. It is built for riders who want more from the engine than the stock CDI gives. Each unit raises the rev limiter and uses an altered ignition advance curve, so the engine keeps pulling past stock redline.

Key Features:

• Higher rev limiter: Raises the rev limiter by about 1,000 RPM over the stock CDI box.
• Altered ignition advance curve: Monocurve technology is designed to improve performance across the RPM range.
• Duplication circuits: Built for maximum reliability.
• Performance-focused design: Increases the RPM redline and changes the ignition advance curve to improve overall engine performance.
• Manufacturer warranty: Backed by a one-year manufacturer warranty.

Quadboss CDI boxes are a plug-in ignition upgrade. They give you a higher redline and better throttle response without a major engine rebuild. This product is not CARB legal and is not for sale in California.
