Looking for a serious BMW B58 cooling upgrade that keeps power consistent on fast road and track? The Wagner Tuning Performance Radiator is the ultimate low temperature radiator and charge cooler heat exchanger for B58-powered BMW M140i, M240i, 340i and 440i. This direct-fit upgrade targets the B58’s indirect charge-air cooling circuit, dropping coolant temperatures to help reduce intake air temps, combat heat soak and maintain reliable performance on stock, Stage 1 and Stage 2 setups.

It is plug-and-play with factory mounts and connections, includes installation instructions and features a durable, heat-conductive anti-corrosion coating for long-term efficiency.
