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 Charge-Air-Cooler (CSF #8082/8082R) & Front Mount Heat Exchanger (CSF #8075/8075V) work together to keep the intake temps down and power up. The factory units simply cannot dissipate enough heat to keep up with prolonged performance driving. CSF's 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. Paired with the Front Mount Heat Exchanger the system is able to maintain lower intake temps and keep your BMW F8X's power up.
