The competition package for the Audi RS4 B9 consists the Intercooler Upgrade Kit and the Radiator Upgrade Kit

Audi RS4 B9 331KW/450PS from 2017

the intercooler upgrade kit 200001162

The 2.9 Liter V6 biturbo engine (VW EA839) of RS4 and RS5 models is equipped with an indirect charge-air cooling circuit. So the cooling of the charged air is realized by a watercooled intercooler which will be replaced by this WagnerTuning high-performance intercooler.

The WAGNERTUNING high-performance intercooler has got 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 directly developed for the high requirements of the RS4/RS5 engine and offers 185 % more external core volume compared to the stock intercooler. The calculated ratio between the inner and outer cooling surface generates a maximum heat transfer and at the same time the best possible internal air flow. The aluminum cast endtanks were designed in CAD and optimized in CFD simulations. The result is an excellent cooling property with a 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).

Advantages of this product:
– significantly better cooling performance
– less pressure drop
– more power and torque for your engine
– mechanical discharge of the turbocharger
– 100% pressure resistance
– 100% Plug and Play
– up to 4 years warranty

the radiator upgrade kit 400001012

The 2.9L V6 biturbo 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 cooling medium (as usual), but made with its own cooling water circuit. A reduction of the temperature of the cooling water is directly equated with an improved cooling performance of the charged air. This is exactly where the advantages of the WAGNERTUNING upgrade water cooler comes into play.
The new developed competition racing core of the WAGNERTUNING high performance water coolers increase 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 and allows at the same time enough air flow for the surrounding components (for example the engine water cooler) for its own heat exchange. The water coolers 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).

Kit comes with:
1x front mounted radiator (low-temperature circuit)
1x Set silicone hoses
