Audi S6 Intercooler - APR - CPS Radiator - '13-'18. APR’s Coolant Performance System is a front-mounted auxiliary radiator engineered to lower intake air temperatures and combat heat soak on the 2013-2018 S6 4.0T.

Built around a dual-pass core, the CPS ties into the factory cooling circuit and is easy to maintain. Louvered fins shed heat quickly as coolant moves through enlarged passages. The self-bleeding design purges trapped air for consistent temps, while the ECU retains full safety control. Each unit is pressure-tested for reliable performance on street and track.
