CSF Top Mount Charge-Air-Cooler, BMW F8X M

The S55 suffers heavily from heat soak. Many tuners witnessed this early on after doing multiple dyno pulls and seeing significant drops in power after each consecutive pass. Many F8X owners experienced the same loss of power on the track as the engine just could not cool off during laps.
The solution is two fold: The CSF Top-Mount Charge-Air-Cooler & Front Mount Heat Exchanger work together to keep intake temps down and power up. The factory units simply cannot dissipate enough heat to keep up with prolonged performance driving. The CSF Charge-Air-Cooler boasts a core size that is 60% larger, greatly increasing the capacity for heat transfer from the hot charge air coming from the turbos.
