The BMW F80 M3, F82/F83 M4 & F87 M2 Comp are still regarded as some of the best performance platforms available. BMW’s S55 Motor has amazing potential for power and there are countless performance parts available for it. However, like most production engines, the S55 doesn’t come equipped from the factory with sufficient cooling capabilities to cope with added power or even prolonged performance driving. We have designed a full line of S55 cooling options to help you get the most out of your BMW F8X. Our Charge-Air-Cooler, Heat Exchanger, and Transmission Cooler will keep you ahead of the competition.

BMW F8X Top Mount Dual-Pass Charge-Air-Cooler

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 & Front Mount Heat Exchanger 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. Our 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.

BMW F8X Front Mount Heat Exchanger

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.
