Superior Cooling for Consistent Power
Engineered to combat heat soak in high-output applications, the Roush supercharger system includes a robust, track-ready cooling package:
Large front-mounted heat exchanger
(installs without removing the front fascia)
High-flow Bosch PCE intercooler pump
Custom high-capacity degas bottle to prevent coolant aeration
Optimized hose routing for improved underhood airflow and appearance
The result is lower intake air temperatures, sustained boost, and repeatable performance lap after lap.

To support increased airflow and boost pressure, the kit features a fully upgraded fuel system:
High-flow dual-cone fuel injectors with optimized director plates
CNC-machined billet fuel rails for maximum flow with minimal restriction
Precision injector orientation for consistent fueling
This system ensures reliable fuel delivery across the entire powerband, even under extreme load.
