DeutschTuning proudly offers CSF Radiator Black Front Mount Heat Exchanger w/ Rock Guard BMW F8X M3/M4/M2. As we discussing with the Charge-Air-Cooler, the S55 power BMW F8X suffers heavily from heat soak. While the ideal solution is pairing the Front Mount Heat Exchanger with the Charge-Air-Cooler, you can still see signification improvements with just the Heat Exchanger. The ability for the system to remove as much heat as possible is the bigger of the two weak points in the system. So if you are planning to upgrade your S55 cooling system and can only start with one, the Heat Exchanger is the right choice to start with. 2-row 42mm Core (Dual Core) Featuring CSF's Exclusive B-tube Technology.
