Wagner Tuning Audi RS4 B9/RS5 F5 Radiator Hoses (OEM IC) Competition – Radiator – Kit
Upgrade your Audi RS4 B9 or RS5 F5 with the Wagner Tuning Competition Radiator Kit. This kit is designed to fit seamlessly with the following models:
- Audi RS4 B9 331KW/450PS from 2017
- Audi RS5 F5 331KW/450PS from 2017
The 2.9L V6 biturbo engine in these Audi models features an indirect charge-air cooling circuit. Unlike traditional systems that use ambient air, this system uses its own cooling water circuit. Reducing the temperature of the cooling water directly improves the cooling performance of the charged air.
The Wagner Tuning upgrade water cooler offers significant advantages. The newly developed competition racing core increases the radiator volume of the OEM water coolers by a total of 55%. The calculated ratio between the inner and outer cooling surface generates maximum heat transfer while allowing sufficient air flow for surrounding components, such as the engine water cooler, to perform their own heat exchange.
These water coolers are equipped with a heat-conductive anti-corrosion coating to ensure lasting cooling performance. The plug & play installation of the system is straightforward and easy to perform, with installation instructions included.
