APR 4.0 TFSI Coolant Performance System (CPS)

Not rated yet

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 the stock B8 unit 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!

Quick Facts:

  • 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 B8
    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.
