Big Gun 07-13 Honda RANCHER 420 Power Box

The Big Gun TFI Power Box is designed for your 2007-2013 Honda Rancher 420. This module works by fine-tuning your ATV's throttle mapping and fuel delivery. It's a straightforward way to get a bit more performance out of your machine, making the throttle feel sharper and the power come on more smoothly, especially in the mid-range where you often need it most.

Installation is plug-and-play, meaning it connects directly into your existing EFI system without needing to reprogram the stock ECU. You can make adjustments on the fly using the buttons on the faceplate, so no computer is required to dial in the fuel injection settings. This third-generation technology is built tough with weather-resistant sealing, ready to handle the bumps and splashes of off-road riding. It's a well-built unit that aims to give you improved throttle response and mid-range torque without compromising the reliability of your Rancher.

This Power Box is especially recommended if you've already upgraded your exhaust system. It installs in just minutes, getting you back on the trail quickly.
