Big Gun 07-14 Kawasaki KFX 450R Power Box

With this Big Gun TFI Power Box, you get the module itself, designed to plug directly into your 2007-2014 Kawasaki KFX 450R's EFI system. This unit is built to make installing an improved throttle and fuel delivery setup straightforward. It's a popular choice for riders looking to get more out of their machine, especially when they've already upgraded the exhaust system.

The TFI Power Box works by fine-tuning how your engine receives fuel and responds to the throttle. You'll notice a sharper throttle response, smoother power delivery through the mid-range, and a noticeable increase in torque. It's designed to work with your stock ECU map, meaning it won't overwrite your factory settings, and you can make adjustments on the fly using the integrated buttons on the faceplate. This third-generation technology is built tough, with weather-resistant sealing to handle the elements you'll encounter off-road.

Installation is typically quick, often taking just a few minutes, and you won't need a computer to make adjustments. This makes it a practical upgrade for riders who want enhanced performance without a complicated setup.
