Big Gun 16-19 Polaris ACE 900 Power Box

Featuring third-generation technology, this Big Gun TFI (Throttle and Fuel Injection) Power Box is built to give your 2016-2019 Polaris ACE 900 a noticeable performance improvement. It works by fine-tuning your vehicle's throttle mapping and fuel delivery, making the powerband feel more responsive and stronger in the mid-range. This is a plug-and-play module, meaning it connects directly into your EFI system without altering the stock ECU map, so you don't have to worry about reliability issues.

You'll find integrated buttons on the faceplate that make it easy to adjust settings on the fly, right from the unit itself – no computer needed. It's designed to be durable, with rugged construction and weather-resistant sealing to handle the tough conditions you might encounter off-road. This power box is especially recommended if you've already upgraded your exhaust system, as it helps get the most out of those aftermarket parts.

Installation is straightforward and can typically be done in minutes. While it offers a significant boost in horsepower and throttle response, it's important to note that this unit is not CARB approved and cannot be shipped to California.
