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 – a true plug-and-play system requiring no modifications to install.

The weak OEM crimped-on plastic end tanks have been replaced with CSF’s larger, CFD analyzed, 100% TIG-welded cast end tanks. The top side of CSF’s Charge-Air Cooling System now features air inlet tanks with seamless integrated charge pipes versus the OEM plastic charge pipes that are glued to the intercoolers. Like the previous F1X model, CSF has again integrated dual 1/8 NPT ports into the outlet side air tanks for quick and easy installation of aftermarket methanol injection systems. The side-specific positioning of these ports have been designed and strategically placed directly into the post-intercooled charge-air stream for maximum performance.

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.
