Description CSF 8351 High Performance Charge Air Coolers for BMW M5 (G90 / G99)
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.
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.
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.

*Fitment Notes:
This product requires some minor modifications to install. The mounting pins that the coolers rest on will need to be shaved down to help the CSF coolers sit in a better position. CSF also recommends trimming the the air balancing tube to improve the fitment. The installation requires fine adjustments and aesthetic results will depend on the skill of the installer.
