Competition Radiator Kit for the BMW F80-82-83 M3/M4
If you’re a fan of the BMW M3 or M4, you know that the 3.0 Liter S55B30 turbo engine is a beast. It features an indirect charge-air cooling system that uses its own cooling water circuit instead of relying on ambient air. This means that keeping the cooling water temperature down directly improves the performance of the charged air. That’s where the WAGNERTUNING upgrade water cooler shines.
The newly developed competition racing cores from WAGNERTUNING boost the radiator volume significantly—by 89% for front-mounted and 94% for side-mounted setups compared to the OEM coolers. The design maximizes heat transfer while ensuring sufficient airflow for other components, like the engine water cooler, to do their job effectively. Plus, these coolers come with a heat-conductive anti-corrosion coating for long-lasting performance. Installation is a breeze with the included plug & play setup and instructions.
