The 2.9L V6 biturbo engine of the Audi RS4 / RS5 is equipped with an indirect charge air cooling circuit.
This means that the charge air is not cooled using the ambient air as a cooling medium (as usual), but with the help of a separate cooling water circuit.
A reduction in the cooling water temperature can therefore be directly equated with an improved cooling performance of the charge air.
This is precisely where the advantages of the WAGNERTUNING upgrade water cooler come into play.

The newly developed competition racing mesh of the WAGNERTUNING high-performance water cooler increases the radiator volume of the standard water cooler by a total of 55%.
The ratio between the inner and outer cooling surface generates maximum heat transfer and at the same time allows the adjacent components (e.g. the engine water cooler located behind it) sufficient air flow for heat exchange.
Furthermore, the water coolers are equipped with a thermally conductive anti-corrosion coating to ensure a long-lasting cooling effect.
Installation of the system is also uncomplicated and plug & play with the help of our installation instructions.
