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!. Please note, the B8 S4/S5 and some C7 A6/A7 require the CPS Fit Kit (MS100136). The fit kit is required when the cooler has an inlet and outlet on opposite sides. Furthermore, some B8 S4/S5 vehicles with Audi Drive Select (ADS) coolers will require custom relocation of the cooler. This cooler is a U shaped cooling fin system visible through the top of the grille.. Fits 2012-2018 Audi A6/A7 Quattro - 2013-2017 Audi Q5 - 2010-2016 Audi S4/S5 - 2013-2018 Audi S6/S7 - 2014-2017 Audi SQ5. Tightly packed external louvered fins rapidly dissipate heat as coolant flows through internal cooling paths.. The self-bleeding system constantly removes air from the system, without any manual intervention!. The ECU retains full control over the system, protecting against pump failure and coolant leaks.. All the performance without the headaches. Each system is fully pressure tested after assembly.. Increases and retains HP while minimizing power-robbing heat soak!. Massive frontal surface area (core) and volume (radiator). Air-bubbles trapped within the system kills performance!. 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. Dramatically lowers intake air temp (IAT).
