CSF prides itself on using the most advanced technologies, machines, and experienced personnel to design, develop, and manufacture the world’s best cooling systems. With three privately owned manufacturing facilities, and a global cooling network formed over the past 75 years, CSF houses the industry’s best machines and brightest minds. Our engineering staff designs many of the machines in-house, giving CSF the innovative edge when introducing new technologies to the industry.



CSF is proud to release the world’s first and industry exclusive BMW F90 M5/F92 M8 High-Performance Charge Coolers – developed alongside long-time R&D partners RK Autowerks.

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.

The CSF Twin Charge Air Cooler Set is a direct replacement for BMW part numbers 17517852406 (right) and 17517852407 (left).
