The APR Coolant Performance System (CPS) is a massive front-mounted cooler upgrade that dramatically reduces intake air temperature (IAT), minimizes heat soak, and provides increased performance! It is 140% larger than stock and features a self-bleeding cooling circuit to ensure it is always operating at peak performance. The system is easy to maintain and fully integrated into the factory cooling circuit. This upgrade is highly recommended at every stage!
Dramatically lowers intake air temp (IAT)
Increases and retains HP while minimizing power-robbing heat soak!
Massive frontal surface area (core) and volume (radiator)
29" x 05.5" x 2.1" – 159.5"² & 054"³ - OEM
22" x 17.4" x 1.7" – 382.8"² & 130"³ - APR
Highly effective dual-pass core design
Tightly packed external louvered fins rapidly dissipate heat as coolant flows through internal cooling paths.
Self-bleeding and self-optimizing system
Air-bubbles trapped within the system kills performance! The self-bleeding system constantly removes air from the system, without any manual intervention!
Retains factory safety and control
The ECU retains full control over the system, protecting against pump failure and coolant leaks.
Easy to install and maintain
All the performance without the headaches. Each system is fully pressure tested after assembly.
The front mounted radiator is tiny. Air trapped within the system devastates the cooler’s effectiveness, while the sheer lack of surface area and coolant volume makes for a system incapable of keeping up with the cooling demands at higher performance levels.
The APR Solution:
The APR Coolant Performance System replaces the front mounted radiator with a much larger and more capable dual-pass unit. It has 140% more frontal surface area and holds 141% more coolant than the factory unit. Tightly packed louvered fins rapidly dissipate heat over a much wider area than the factory unit.
Next, APR CPS incorporates a unique self-bleeding system into the cooler design. Keeping up with manual bleeding is messy, and all but impossible. However, the APR system continuously self-bleeds, increasing the coolers effectiveness automatically!
The result is simple: More horsepower over a much wider operating range!
