WAGNER TUNING Performance Intercooler Kit (Audi RS 4 B9 & RS 5 F5)

The 2.9 Liter V6 biturbo engine (VW EA839) of RS4/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 will be replaced by this Wagner Tuning high-performance intercooler.

The WAGNER TUNING 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 end tanks 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 WAGNER TUNING 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
