Big Gun 14-23 Honda RANCHER 420 Straight Axle Power Box

Big Gun is known for making performance exhaust systems for powersports vehicles, and their TFI Power Box is a solid addition to that lineup. This module is designed to give your 2014-2023 Honda Rancher 420 Straight Axle a noticeable performance improvement by fine-tuning how your engine handles throttle input and fuel. If you're looking to get more out of your ATV, especially if you've already upgraded the exhaust, this is a smart way to go.

What this box does is essentially smooth out the power delivery and sharpen up the throttle response. You'll feel a difference in how quickly the engine reacts when you twist the throttle, and it also helps to increase mid-range torque, which is really useful for getting out of tight spots or accelerating through the gears. It's built tough, with rugged construction and weather-resistant seals, so it can handle the kind of conditions you'd expect to encounter off-road. Plus, it installs easily as a plug-and-play unit, meaning it connects directly into your EFI system without needing a computer for adjustments.

This is a third-generation technology from Big Gun, and it's designed to work with your stock ECU map without interfering with it. You can make adjustments on the fly using the integrated buttons on the faceplate, which is handy when you're out riding and want to fine-tune the performance. It's a straightforward way to get a bit more horsepower and a more responsive feel from your Rancher.
