Description:
The Max Cooling Upgrade increases your engine and supercharger system's cooling capacity by allowing more airflow into and out of the engine compartment.. No required for Roush build Stage vehicles.
Upgrade your 2018-2023 ROUSH Supercharged Mustangs cooling capacity with the ROUSH Max Cooling Upgrade. What's included: Auxiliary Engine Cooler (Driver Side) Auxiliary Supercharger Cooler (Passenger Side) (2) Fender Heat Extractors (2) Gloss Black Front Fascia Corner PocketThe ROUSH Max Cooling Upgrade fits 2018-2023 Ford Mustangs equipped with the 5.0L engine and ROUSH R2650 Supercharger. The additional coolers increase cooling capacity while the fender vents allow excess heat to escape and allow more airflow. ROUSH Performance recommends updating to the latest ROUSH Calibration after the Max Cooling Kit has been installed. Integrated into the calibration is our Engine Cool Down Feature. This feature allows you to activate a 3-minute cool-down by holding the brake and pressing the ?SET+ button on your steering wheel. This will initiate the fans and force hot air out of the engine compartment to keep your motor and supercharger cool between passes at the track.
