The CSF Top Mount Charge-Air-Cooler (Crinkle Black) is a high-performance intercooler upgrade designed for the BMW F80 M3, F82/F83 M4, and F87 M2 Competition with the S55 twin-turbo engine. As a thermo-optimized replacement for the restrictive OEM unit, this top-mount intercooler increases core size by approximately 60 %, dramatically improving heat rejection and helping keep intake air temperatures lower under sustained load — crucial for maintaining power and reducing detonation risk during spirited driving or track sessions. Its dual-pass, cross-flow core design with cast end tanks and optimized internal air dividers enhances airflow management and thermal efficiency versus stock configurations, all while fitting as a true “drop-in” solution.
Designed for BMW F80 M3 (2015–2018), F82/F83 M4 (2015–2020), and F87 M2 Competition (2019–2021) with the S55 3.0 L twin-turbo engine.
Replaces the factory top-mount intercooler (charge-air cooler); integrates with OEM water lines and sensor ports.
Drop-in installation uses OEM-style quick-connect fittings — no trimming or modification required.
Best when combined with a front-mount heat exchanger and upgraded charge piping for complete intake cooling optimization.
Top-mount charge-air cooler available in either raw or crinkle black powder-coated finish for corrosion resistance and OEM-plus appearance.
Precision cast end tanks with internal air dividers.
All OEM-style quick-connect water fittings and sensor ports.
Installation documentation/guide.
