max cooling package

supercharged 5.0l v8 mustang gt

The perfect cooling upgrade for your supercharged Mustang

$4,950.00 FITTED



We are excited to offer the same auxiliary cooling system for your 2018, 2019, 2020, 2021, 2022, or 2023 Supercharged Mustang that is installed on every 2021 ROUSH Stage 3 production vehicle. The Max Cooling Upgrade increases your engine and supercharger system’s cooling capacity by allowing more airflow into and out of the engine compartment.

The front fascia corner pockets aren’t there just for looks. They are functional and allow for more airflow through the front bumper while giving your Mustang a more aggressive appearance. CAD-designed steel brackets are used to mount the coolers behind the fascia for an OE appearance and fitment. Formed hoses are used for the best installation experience and fitment with quick connect fittings. (No relocation of windshield washer bottle is required with this kit).

In order for the low-temp radiator and auxiliary heat exchangers to function properly, they require airflow across their surfaces to transfer heat from the low-temp radiator to the air. The fender vents allow air to escape from underneath the hood thereby reducing the underhood pressure and allow more airflow across the heat exchangers. The factory fender liners are also modified during installation to allow airflow through the fender wells instead of being trapped behind the fascia.
