CSF High-Performance Charge-Air-Coolers for G90 / G99 BMW M5 [8351]

Engineered for the demands of BMW’s new G90 M5 and G99 M5 Touring, CSF’s High-Performance Charge-Air-Coolers address a critical bottleneck on the S68 platform. With the S68 already proven to deliver 900+ whp on stock internals, the resulting heat and pressure can overwhelm the fragile factory coolers. CSF resolves this limitation by revising its proven S63 / S68 charge-air-cooler design specifically for the G90 / G99, delivering greater durability and thermal headroom to support elevated power targets. Finished in an OEM+ Crinkle Black, these units blend seamlessly with the engine bay while providing the robustness and efficiency required for consistent, reliable performance.

OEM vs CSF

CSF’s charge-air-cooler cores offer approximately 100% greater volume than the factory units. Designed through CFD analysis and validated in testing, the cores deliver optimal performance with precise fitment. Both coolers feature OEM-style quick-connect water fittings and integrated sensor ports for fast, straightforward installation. For additional details and performance data, see the full press release on the CSF #8178 coolers.
CSF replaces the weak OEM crimped plastic end tanks with larger, CFD-analyzed, 100% TIG-welded cast units. The charge pipe is integrated into the upper end tank, eliminating the glued-on factory plastic charge pipes and creating a single-piece cast assembly engineered to withstand substantially higher boost pressures. For added versatility, dual 1/8″ NPT ports are incorporated on both outlet-side air tanks, enabling quick installation of aftermarket methanol or nitrous injection. These ports are strategically positioned to introduce the injection directly into the post-intercooled charge-air stream for maximum performance.
