The Wagner Tuning Competition Water Cooler Kit was specially developed for the Audi RS4 B9 and Audi RS5 F5 . These models are equipped with a 2.9L V6 biturbo engine that features an advanced indirect charge air cooling system. Unlike traditional systems, the charge air is not cooled by ambient air, but by a separate cooling water circuit. As a result, a reduction in the cooling water temperature directly leads to improved charge air cooling performance. This is where the advantages of the Wagner Tuning Upgrade water cooler come into their own. The newly developed competition core of the high-performance water cooler increases the radiator volume of the standard water cooler by as much as 55% . Thanks to the optimized ratio between the inner and outer cooling surface, maximum heat transfer is guaranteed while sufficient airflow is maintained to adjacent components, such as the engine water cooler. In addition, the water coolers are equipped with a thermally conductive anti-corrosion layer, which ensures a long-lasting cooling effect. Installing the system is simple and virtually plug & play, thanks to our user-friendly installation instructions. This means you can quickly enjoy the benefits of the Wagner Tuning Water Cooler Kit, which is designed to take the performance of your Audi RS4 B9 or RS5 F5 to the next level. Experience improved performance and reliability with the Wagner Tuning Competition Water Cooler Kit , which is perfectly tailored to the requirements of the 2.9L V6 biturbo engine . Upgrade your Audi and enjoy optimal cooling on every journey!
