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.
