Maximize the performance of your Audi S4/S5 with the Wagner Tuning additional water cooler kit. The 3.0L V6 supercharged engine of the Audi S4 and S5 models is a technical masterpiece. But even the best engines can benefit from optimization. Our auxiliary water cooler kit is the solution for improved cooling performance and optimized efficiency. In contrast to conventional cooling with ambient air, our system uses its own cooling water circuit. This enables a direct reduction in the cooling water temperature and leads to a noticeable improvement in the cooling performance of the charge air. Our new competition racing network increases the radiator volume of the standard water cooler by an impressive 92%. The intelligent ratio between the inner and outer cooling surface ensures maximum heat transfer. At the same time, sufficient airflow is ensured for heat exchange with adjacent components. In addition, our water coolers are equipped with a thermally conductive anti-corrosion coating that ensures a long-lasting cooling effect. Installation of the system is straightforward and virtually plug & play thanks to our detailed installation instructions. Increase the performance and reliability of your Audi S4/S5 with the Wagner Tuning additional water cooler kit.
