Audi RS4 2.9 TFSI [B9] Wagner Competition Radiateur Kit
Competition water cooler kit for Audi RS4 B9 / RS5 F5 Plug and Play suitable for the following models: Audi RS4 B9 331KW/450hp from 2017Audi RS5 F5 331KW/450hp from 2017 The 2.9L V6 biturbo engine of the Audi RS4 / RS5 is equipped with an indirect charge air cooling circuit. As a result, the cooling process of the charge air is not realized (as usual) with the ambient air as a cooling medium, but is carried out with the help of a separate cooling water circuit. A reduction in the cooling water temperature can therefore be directly equated with improved charge air cooling performance. This is exactly 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 cooling volume of the standard water cooler by a total of 55%. The ratio between inner and outer cooling surface generates maximum heat transfer and at the same time allows the adjacent components (e.g. the engine water cooler behind it) sufficient air flow for its heat exchange. Furthermore, the water coolers are equipped with a heat-conducting anti-corrosion coating to ensure a long-lasting cooling effect. The installation of the system is also uncomplicated and plug & play with the help of our installation instructions. Dimensions OEM water cooler:720 mm x 485 mm x 25 mmV = 8.73 litersA = 3492 cm² WT water cooler dimensions:690 mm x 490 mm x 40 mmV = 13.52 litersA = 3381 cm
