The 2.9 Liter V6 Biturbo engine (VW EA839) of RS5 models is equipped with an indirect charge-air cooling circuit. So the cooling of the charged air is realized by a water-cooled intercooler which this WagnerTuning high-performance intercooler will replace.

The WAGNERTUNING high-performance intercooler has a new performance core with the external core dimensions 222 mm x 200 mm x 120 mm / 8,74Inch x 7,87Inch x 4,72Inch. This intercooler core was developed for the high requirements of the RS4/RS5 engine and offered 185 % more external core volume than the stock intercooler.

The calculated ratio between the inner and outer cooling surface generates a maximum heat transfer and, simultaneously, the best possible internal airflow. The aluminum cast end tanks were designed in CAD and optimized in CFD simulations. The result is an excellent cooling property with minimal back pressure. That`s why this kit is also perfect for racing use. An optimal cooling effect of the charged air with a significant increase in performance!

All WAGNERTUNING radiators are equipped with a heat-conductive anti-corrosion coating to ensure a lasting cooling effect. The plug & play installation of the system is simple and easy to perform (an installation instruction is included as well).

The 2.9L V6 bi-turbo engine of Audi RS4 / RS5 models is equipped with an indirect charge-air cooling circuit. So the cooling of the charged air is not realized by the ambient air as a cooling medium (as usual), but made with its cooling water circuit. A reduction in the temperature of the cooling water is directly equated with an improved cooling performance of the charged air. 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 coolers increases the radiator volume of the OEM water coolers by a total of 55 %. The calculated ratio between the inner and outer cooling surface generates a maximum heat transfer.

It allows at the same time enough airflow for the surrounding components (for example, the engine water cooler) for its heat exchange. The water coolers have a heat-conductive anti-corrosion coating to ensure a lasting cooling effect. The plug & play installation of the system is simple and easy to perform (an installation instruction is included as well).

The kit comes with:

1x front-mounted radiator (low-temperature circuit)
1x Set silicone hoses
1x mounting material
1x installation instruction
