Performance INTERCOOLER KIT Audi RS4 B9 / RS5 F5
The 2.9 Liter V6 biturbo engine (VW EA839) in the RS4 and RS5 models comes with an indirect charge-air cooling system. This means that the charged air is cooled using a water-cooled intercooler, which can be upgraded to the WagnerTuning high-performance intercooler for better performance.
The WAGNERTUNING intercooler features a new performance core with external dimensions of 222 mm x 200 mm x 120 mm (8.74 inches x 7.87 inches x 4.72 inches). This core has been specifically designed to meet the high demands of the RS4/RS5 engine, offering a whopping 185% increase in external core volume compared to the stock intercooler. The design ensures maximum heat transfer and optimal internal airflow, thanks to the CAD-designed aluminum end tanks that have been optimized through CFD simulations. This results in excellent cooling properties with minimal back pressure, making it ideal for racing applications. You can expect a significant boost in performance with improved cooling of the charged air!
All WAGNERTUNING intercoolers come with a heat-conductive anti-corrosion coating to maintain a lasting cooling effect. Plus, the installation is straightforward with a plug & play design, and an installation guide is included.
