The 2.0L M133 turbo engine of the specified A-Class models from AMG 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 Wagner Tuning upgrade water cooler comes into play.

The newly developed competition racing core of the Wagner Tuning high-performance water coolers increases the radiator volume of the OEM water coolers by a total of 78 %. The calculated ratio between the inner and outer cooling surface generates a maximum heat transfer and allows at the same time enough airflow for the surrounding components 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.

  • OEM front-mounted radiator size 640mm x 390mm x 16mm
