Optimize the cooling performance of your BMW G80/G81/G82 M3/M4 with our water cooling kit.
The 3.0L R6 (S58) biturbo engine in the BMW M3/M4 models features an indirect charge air cooling circuit. This means that the charge air is not cooled by ambient air as usual, but by its own cooling water circuit. A reduction in the cooling water temperature directly improves the charge air cooling performance. This is where the benefits of our Wagner Tuning Upgrade water cooler come into play. Our new racing mesh increases the volume of the standard radiator by an impressive 60%. The ratio of internal to external cooling surfaces ensures maximum heat transfer while allowing sufficient airflow to adjacent components such as the engine radiator. The water coolers also feature a thermally conductive anti-corrosion coating, ensuring long-lasting cooling. Our installation instructions make system installation simple and plug-and-play.
Prepare your BMW G80/G81/G82 M3/M4 for maximum performance and optimize its cooling system with our radiator kit.
