Wagner Tuning Heat Exchanger Kit - Audi B9/9.5 RS4/RS5 2.9T

Discover the Wagner Tuning Competition Water Cooler Kit, specially developed for the Audi RS4 B9 and Audi RS5 F5.

- Reduction of the cooling water temperature
- Competition racing mesh increases the radiator volume of the standard water cooler by 55
- Optimised ratio between inner and outer cooling surface
- Thermally conductive anti-corrosion coating for long-term cooling effect
- Easy installation thanks to user-friendly installation instructions (almost plug & play)

The 2.9L V6 biturbo engine of these models is equipped with an advanced indirect charge air cooling circuit. Unlike conventional systems, the charge air cooling process is not realized by ambient air, but by a separate cooling water circuit. A reduction in the cooling water temperature therefore leads directly to an improved cooling performance of the charge air. This is where the advantages of the Wagner Tuning Upgrade water cooler come into their own.

The newly developed competition racing core of the Wagner Tuning high-performance water cooler increases the radiator volume of the standard water cooler by an impressive 55%. The optimized ratio between the inner and outer cooling surface ensures maximum heat transfer and at the same time guarantees sufficient air flow for adjacent components such as the engine water cooler. In addition, the water coolers are equipped with a thermally conductive anti-corrosion coating that ensures a long-term cooling effect. Installation of the system is straightforward and virtually plug & play thanks to our user-friendly installation instructions.
