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
Audi RS5 F5 331KW/450PS from 2017
The 2.9 Liter V6 biturbo engine (VW EA839) of RS4 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.
The 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 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 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 upgrade water cooler comes into play.
The new developed competition
racing core of 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).

1x front mounted
