BMW M3/M4 Competiotion Radiator Kit by Wager Tuning
The 3.0 Liter S55B30 turbo engine for BMW M3/M4 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 cores of the WAGNERTUNING high
performance water coolers increase the radiator volume of the OEM water coolers by 89% for
front mounted and 94% for side mounted. 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).
