Wagner Tuning Comp. Package Audi RS4 B9 water cooler/intercooler

The Competition Package for the Audi RS4 B9 consists of the intercooler upgrade kit and the water cooler upgrade kit.

Audi RS4 B9 331KW/450PS from 2017

The intercooler upgrade kit:

The 2.9-liter V6 biturbo engine (VW EA839) in the Audi RS4 models is equipped with an indirect charge air cooling system. The charge air cooling process is therefore achieved by a water-cooled intercooler, which is replaced by the WagnerTuning high-performance intercooler.

The WAGNERTUNING high-performance intercooler features a novel performance core measuring 222 mm x 200 mm x 120 mm. Specifically developed to meet the demanding requirements of the RS4/RS5 engine, it offers 185% more external core volume compared to the original intercooler. The optimized ratio of internal to external cooling surface area ensures maximum heat transfer while simultaneously allowing for the best possible internal airflow. The cast aluminum end tanks were designed using CAD and optimized with CFD simulations. The result is outstanding cooling performance with minimal backpressure. This kit is therefore also suitable for racing applications. Optimal cooling of the charged air leads to a significant increase in power!

All WAGNERTUNING intercoolers are equipped with a heat-conducting, anti-corrosion coating, ensuring long-lasting cooling performance. Installation of the system is also straightforward and plug-and-play thanks to our installation instructions. & play feasible.

Advantages of this product:

• - significantly improved cooling performance
• - less resistance
• - More power and torque for your engine
• - mechanical relief of the turbocharger
• - 100% compressive strength
• - 100% Plug and Play
• - Up to 4 years warranty

The water cooler upgrade kit:

The 2.9L V6 biturbo engine of the Audi RS4/RS5 is equipped with an indirect charge air cooling system. The charge air is therefore not cooled using ambient air as the cooling medium (as is usually the case), but rather with a dedicated coolant circuit. A reduction in coolant temperature thus directly translates to improved charge air cooling performance. This is precisely where the advantages of the WAGNERTUNING upgrade water cooler come into play.

The newly developed Competition racing core of the WAGNERTUNING high-performance water cooler increases the cooling volume of the standard water cooler by a total of 55%. The ratio of inner to outer cooling surface area generates maximum heat transfer while simultaneously allowing sufficient airflow to adjacent components (e.g., the engine water cooler behind it) for their heat exchange. Furthermore, the water coolers are equipped with a heat-conducting, anti-corrosion coating, ensuring long-lasting cooling performance. Installation of the system is also straightforward and plug-and-play, thanks to our installation instructions. & play feasible.
