1999-2004 TRX 400EX Rev Box (BIG40-R01)

The Big Gun Rev Box for the Honda TRX 400EX is a high-performance electronic upgrade designed to unlock the full potential of your engine. As an affordable alternative to expensive OEM replacement CDI boxes, this unit is engineered to provide a more aggressive power delivery. By increasing the overall RPM limit and advancing the timing curve, the Big Gun Rev Box allows your engine to pull harder for longer, providing a noticeable boost in top-end speed and acceleration.

Features

• Increased RPM Limit: Raises the factory rev ceiling, allowing the engine to reach higher RPMs before the limiter engages.
• Advanced Timing Curve: Optimizes ignition timing to provide improved throttle response and increased horsepower throughout the rev range.
• Cost-Effective Performance: Offers a significant performance gain at a fraction of the cost of many factory replacement electronic components.
• Plug-and-Play Installation: Designed to easily replace the stock CDI box for a straightforward performance upgrade.
• Enhanced Power Delivery: Specifically tuned to work with both stock and modified engines to maximize power output.

Notes

• Direct replacement for the factory CDI/Rev box.
• Optimized for the Honda TRX 400EX (1999-2004) ignition system.
• Works best when paired with a high-flow exhaust and air filter for maximum performance.
