Audi RS6 / RS7 C7 4.0 BiTurbo Radiator Kit

Optimize the cooling performance of your Audi RS6 / RS7 C7 with our competition water cooler kit.

The 4.0L V8 biturbo engine of the Audi RS6 and RS7 models is equipped with an indirect charge air cooling circuit. The cooling process of the charge air is therefore not realized with ambient air as usual, but with a separate cooling water circuit. A reduction in the cooling water temperature leads directly to an improved cooling performance of the charge air. This is where the advantages of our Wagner Tuning auxiliary water cooler come into play. Our newly developed competition racing core increases the radiator volume of the standard water cooler by an impressive 102%. The ratio between the inner and outer cooling surface ensures maximum heat transfer and at the same time allows sufficient airflow for adjacent components such as the engine water cooler. The water coolers are also equipped with a thermally conductive anti-corrosion coating, which ensures a long-term cooling effect. Installation of the system is uncomplicated and plug & play thanks to our installation instructions.

Prepare your Audi RS6 / RS7 C7 for maximum performance and optimize its cooling system with our competition water cooler kit.
