CSF is the world leader in BMW air-to-water charge-air cooling technology. From its experience starting with its industry-leading one-piece S55 Charge Cooler, to then developing the world¡¯s first Charge-Air Cooling System for the F1X M5/M6, CSF applied several different features exclusive to its manufacturing technologies to create its newest and most innovative Charge-Air Cooling System for the F9X M5 and M8.

This new design truly tested the engineering and manufacturing capabilities of CSF, with over one year of development and several prototype revisions to achieve absolutely perfect fitment into an engine bay with only a few millimeters to spare ¨C a true plug-and-play system requiring no modifications to install

Real-World Performance Improvements

Before finally releasing these new charge coolers to the market, CSF worked with RK Autowerks to install, verify perfect fitment, and conduct performance testing on two of the world¡¯s fastest and most powerful F90 M5 Sedans.
