CSF 2025+ BMW G90 M5 / G99 M5 Touring Charge Air Cooler

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. The CSF Charge-Air-Coolers boast a nearly 100% larger core size than factory per side. This greatly increases the capacity for heat transfer from the hot charge air from your G90 M5 or G99 M5 Touring's Turbos. The CSF #8351 Cooling product is designed to be a "Drop-In Fit" application. The product will install in the OEM Location with no modifications necessary unless otherwise noted or instructions are included in the product package. Please see the manufacturer repair manual for standard installation instructions. If you do not feel confident installing this product CSF recommends taking it to a qualified installation facility.

The CSF Charge Air Cooler set for the BMW G90 M5 and G99 M5 Touring is designed to deliver exceptional thermal management for high-performance applications. Originally developed for the F9X M5/M6, these intercoolers have proven their effectiveness on over 500 setups, many exceeding 1,000 horsepower. Thanks to collaborative R&D with industry leaders like IND Distribution, Evolve, Eventuri, and R44 Performance, CSF has engineered a drop-in fit kit that guarantees a straightforward installation without extensive modifications. The intercoolers feature nearly double the core volume of OEM units, significantly enhancing heat transfer capacity to keep intake temperatures lower during demanding driving conditions. This reduction in intake air temperatures improves overall engine efficiency, throttle response, and power output, especially on tuned or forced induction setups. The kit includes both left and right charge-air coolers, complete installation hardware, OEM-style quick connect water connections, and sensor ports, ensuring compatibility and ease of installation. Constructed with a durable crinkle black powder-coated finish, the intercoolers also incorporate custom-designed liquid-to-air cores with CFD-optimized performance, integrated E85/methanol injection ports, and seamless air inlet end tanks with integrated charge pipes. The design emphasizes precise fitment through advanced 3D scanning and rapid prototyping technology. These intercoolers are sold as a complete set, providing a reliable upgrade for drivers seeking improved cooling capacity and performance. With a lifetime warranty, the CSF G90 M5 / G99 M5 Touring charge air coolers are an essential component for maximizing the potential of your high-performance BMW, especially in heavily tuned applications or track use. Please note that installation may require minor modifications for optimal fitment, and professional installation is recommended for best results.
