Twin Charge-Air Cooler Set

The CSF Radiators #8178 is a high-performance twin charge-air cooler set engineered for BMW F9X M5 and M8 vehicles. CSF, a leader in BMW air-to-water charge-air cooling technology, developed this innovative system with over a year of rigorous testing and prototype revisions to ensure a perfect fit with minimal clearance. It features a 1-piece seamless air inlet end tank with integrated charge pipes, replacing the OEM plastic charge pipes that are glued to the intercoolers. This charge-air cooler set boasts a nearly 100% increase in core volume per side compared to the factory units, significantly enhancing heat transfer capacity. The construction utilizes CSF's larger, CFD-analyzed, 100% TIG-welded cast end tanks, which replace the weaker OEM crimped-on plastic end tanks. Integrated dual 1/8 NPT ports are strategically placed on both outlet side air tanks, allowing for quick and easy installation of aftermarket methanol or nitrous injection systems directly into the post-intercooled charge-air stream for maximum performance. The CSF #8178 is designed as a "drop-in fit" system, requiring no modifications for installation. It comes complete with OEM-style "quick connect" water connections and sensor ports, along with all necessary installation hardware. This set is available in an OEM+ Crinkle Black finish, with a wide variety of custom finishes offered at an additional cost, including Thermal Dispersion Black, various powder-coated options, and DLC coatings. This charge-air cooler set is compatible with 2019-2022 BMW M5 (F90) models (including Competition and CS trims), and 2018-2024 BMW M8 (F91/F92/F93) models (including Competition and Gran Coupe trims), all featuring the Turbocharged 4.4L V8 engine. The product significantly reduces Intake Air Temperatures (IATs) and is tested to improve 60-130MPH times by approximately 0.3 seconds. It is backed by a lifetime warranty.
