Overview

The Wagner Tuning Audi S6/S7 C7 4.0 BiTurbo Radiator Kit is a direct replacement for the original water cooler in the Audi S6 and S7 (C7) models with the 4.0L V8 twin-turbocharged engine. It features a competition racing core that provides 92% more core volume than the stock unit. This increased volume allows for more efficient heat removal from the coolant, leading to lower charge air temperatures and denser intake air.
