Competition – Radiator – Kit for Audi RS4 B9 / RS5 F5

The Audi RS4 and RS5 are powered by a robust 2.9L V6 biturbo engine, which features an indirect charge-air cooling system. Unlike traditional setups that use ambient air for cooling, this system utilizes its own cooling water circuit. Lowering the temperature of the cooling water directly enhances the cooling performance of the charged air, and that’s where the WAGNERTUNING upgrade water cooler shines.

The newly developed competition racing core of the WAGNERTUNING high-performance water coolers boosts the radiator volume of the OEM units by an impressive 55%. The design optimizes the ratio between the inner and outer cooling surfaces, maximizing heat transfer while ensuring sufficient airflow for surrounding components, like the engine water cooler, to perform their own heat exchange. Plus, these coolers come with a heat-conductive anti-corrosion coating to maintain a long-lasting cooling effect. Installation is straightforward, and an instruction manual is included to guide you through the process.
