Whipple Superchargers Open Air Box Kit (24+ Mustang)

The new Open Air Box for the 2024–2025 Whipple Supercharged S650 Mustang is engineered to deliver serious performance gains and an even more engaging driving experience.

Designed specifically for the S650 platform, this system maximizes airflow to the supercharger, allowing it to breathe freely and operate with greater efficiency. By sealing against the underside of the hood, the airbox isolates the intake from the heat of the engine bay and channels cooler, denser air from the front of the vehicle—an essential factor in achieving optimal combustion and consistent power delivery. The result is a noticeable increase in horsepower and throttle response, giving your Mustang sharper performance on both the street and the track.

Beyond the performance advantages, the open design also enhances the distinct Whipple supercharger whine, amplifying one of the most satisfying sounds in the Mustang world. For enthusiasts looking to elevate both the power and personality of their Whipple Supercharged S650, this open air box is a must-have upgrade that blends form, function, and unmistakable sound.
