CSF 8178 Twin Charge-Air-Cooler Set for Select 2018-2025 BMW M5 & M8 (S63) - Crinkle Black

Fits select 2018-2025 BMW M5 and M8 models (V8-4.4L Twin-Turbo S63 engine).

As the BMW S63 engine is tuned for higher output, managing Intake Air Temperatures (IATs) becomes the primary bottleneck for consistent performance. The CSF 8178 Twin Charge-Air-Cooler Set is a high-performance, liquid-to-air cooling solution engineered to replace the restrictive factory units. Utilizing advanced CFD analysis and 3D scanning, CSF developed a core that maximizes available engine bay volume, resulting in a 100% increase in core volume per cooler compared to the OEM units.

To ensure structural integrity under high-boost applications, these coolers feature a one-piece seamless air inlet end tank with integrated charge pipes, eliminating the failure points associated with multi-piece designs. Each unit includes dual 1/8 NPT ports for the seamless integration of methanol or E85 injection. This drop-in kit preserves factory serviceability with OEM-style quick-connect water fittings and sensor ports, requiring no vehicle modifications for installation.
