Big Gun 14-16 Polaris ACE 325 Power Box

Big Gun is known for making performance exhaust systems and engine tuning components for powersports vehicles. This TFI (Throttle and Fuel Injection) Power Box is designed to give your 2014-2016 Polaris ACE 325 a noticeable performance upgrade. It works by fine-tuning how your engine responds to the throttle and how it manages fuel delivery, making the whole powerband feel more connected and responsive.

You'll find that installing this unit is straightforward thanks to its plug-and-play design, meaning it connects directly into your EFI system without needing to reprogram the stock ECU. This unit is built tough, with rugged construction and weather-resistant sealing, so it can handle the rough conditions you'll likely encounter off-road. It's especially recommended if you've already upgraded your exhaust, as it helps get the most out of those modifications by smoothing out power delivery and boosting mid-range torque without compromising the reliability of your ACE 325.

Adjusting the settings is also simple, with integrated buttons right on the faceplate, so you won't need a computer to dial in the EFI. This third-generation technology is designed to install in minutes, giving you an improved horsepower and throttle response experience.
