Audi S6 / S7 C7 4.0 BiTurbo Radiator Kit

Maximize the performance of your Audi S6 / S7 C7 with the Competition water cooler kit from Wagner Tuning.

The 4.0L V8 biturbo engine of the Audi S6 and S7 models is equipped with an innovative indirect charge air cooling circuit. In contrast to conventional systems, the charge air is not cooled with ambient air, but with its own cooling water circuit. The reduction of the cooling water temperature leads directly to an improved cooling performance of the charge air - and this is exactly where the Wagner Tuning additional water cooler kit comes in.

Our newly developed competition racing core increases the radiator volume of the standard water cooler by an astonishing 92%. The unique ratio between the inner and outer cooling surface enables maximum heat transfer and ensures that adjacent components receive sufficient airflow for their heat exchange. In addition, our water coolers are equipped with a thermally conductive anti-corrosion coating that ensures a long-term cooling effect.

Installation of the system is simple and straightforward thanks to our detailed installation instructions. Enjoy the benefits of an improved cooling circuit and experience optimised performance from your Audi S6 / S7 C7.
