BMW G9X M5 High-Performance Charge-Air-Coolers

CSF originally designed the BMW S63 Charge-Air-Coolers for the F9X M5/M6. Over five hundred of these Intercooler kits have been sold with many of them on 1000+ hp builds. Due to the popularity and success of these previous kits, it wasn't long before our dealers and tuning partners got their hands on these new M5s. With a little R&D/Test fitting help from the likes of IND Distribution, Evolve/Eventuri, and R44 Performance, CSF quickly developed a new drop-in fit kit for the G90 and G99 M5.; Integrated dual 1/8 NPT ports are located on both outlet side air tanks for quick and easy installation of aftermarket methanol/nitrous injection systems. The positioning of these ports have been carefully designed to place the injection system directly into the post-intercooled charge-air stream for maximum performance.; Real world testing on these coolers was originally performed on a Stage 3 F90 M5 with 900whp. While the vehicles differ slightly, the overall performance gains/results will be similar. These coolers are currently installed on the top 5 world's fastest S63 powered M cars. This includes Mr. Vanos 1200+ HP F90 M5. The G9X kit was dyno tested at 1000HP with just a tune prior to launch.; The CSF Charge-Air-Cooler Cores are 100% larger in volume than the factory coolers. CFD analysis and testing was used to design the cores ensuring optimal performance as well as perfect fitment. Both coolers come with OEM-Style "Quick Connect" water connections as well as sensor ports for fast and easy installation. You can read the full press release of the full press release of the CSF #8178 Coolers for more details & performance data.; The weak OEM crimped-on plastic end tanks have been replaced with CSF's larger, CFD analyzed, 100% TIG-welded cast end tanks. CSF also integrated the charge pipe into the design of the top end tank eliminating the glued-on factory plastic charge pipes. This single piece cast design creates a much stronger system that can handle much higher boost pressures.
