Wagner Tuning BMW G80/G81/G82 M3/M4 Radiator Kit

The 3.0L R6 biturbo engine (S58) of the BMW M3/M4 models is equipped with an indirect charge air cooling circuit. The cooling process of the charge air is therefore not realized with ambient air as usual, but with a separate cooling water circuit. A reduction in the cooling water temperature leads directly to an improved cooling performance of the charge air. This is where the advantages of our Wagner Tuning Upgrade water cooler come into play. Our newly developed competition racing core increases the radiator volume of the standard water cooler by an impressive 60%. The ratio between the inner and outer cooling surface ensures maximum heat transfer and at the same time allows sufficient airflow for adjacent components such as the engine water cooler. The water coolers are also equipped with a thermally conductive anti-corrosion coating, which ensures a long-term cooling effect.

Fits: BMW S58: M3 (G80/G81), M4 (G82/G83). Confirm your exact car with us before ordering.
