Wagner Tuning | Competition water cooler + intercooler | Audi RS4/RS5 (B9/8W/F5) 2.9 TFSI 450hp

The competition package for the Audi RS4 B9 consists of the intercooler upgrade kit and the water cooler upgrade kit.

Suitable for the following models:
Audi RS4 B9 331KW/450hp from 2017
Audi RS5 F5 331KW/450hp from 2017

The intercooler upgrade kit:
The 2.9 litre V6 biturbo engine (VW EA839) of the Audi RS4 models is equipped with an indirect charge air cooling circuit. The charge air cooling process is therefore realised by a water-cooled charge air cooler, which is replaced by the WagnerTuning high-performance charge air cooler.

The WAGNERTUNING high-performance intercooler has a new type of performance mesh with dimensions of 222 mm x 200 mm x 120 mm. This was specially developed for the high demands of the RS4/RS5 engine and offers 185% more external mesh volume compared to the original intercooler. The ratio between the inner and outer cooling surface generates maximum heat transfer and at the same time enables the best possible internal air flow. The cast aluminium end boxes were designed in CAD and optimised with the aid of CFD simulations. The result is excellent cooling properties with minimal back pressure. This kit is therefore also suitable for racing. Optimum cooling of the supercharged air with a significant increase in performance!

All WAGNERTUNING intercoolers 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.

Advantages of this product:
- Significantly better cooling performance
- Less back pressure
- More power and torque for your engine
- Mechanical relief of the turbocharger
- 100% pressure resistance
- 100% plug and play
- Up to 4 years warranty

The water cooler upgrade kit:
The 2.9 litre V6 biturbo engine of the Audi RS4 / RS5 is equipped with an indirect charge air cooling circuit. This means that the charge air cooling process is not realised 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 neighbouring components (e.g. the engine water cooler behind it) sufficient airflow 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 straightforward and plug & play with the help of our installation instructions.
