Product Description

The CSF 8082 is a race-inspired, top-mount charge-air cooler engineered specifically for the S55-powered BMW F8X platform--M3, M4, and M2 Competition (2015-2021). It features a cast-endtank, dual-pass design and a core 60 % larger than stock. This layout reduces intake air temperatures dramatically during spirited driving or dyno sessions, addressing heat-soak issues found in the factory setup. :contentReference[oaicite:9]{index=9}

Precision-engineered via 3D scanning and CFD analysis, the cooler integrates multiple air dividers and multi-louvered fins within a 42 mm B-Tube core. It also uses OEM quick-connect fittings and plug-and-play mounting, fitting neatly into factory brackets--no cutting or trimming required. Choose crinkle black for stealth styling or raw aluminum for customialization; both options come backed by CSF's lifetime warranty. :contentReference[oaicite:10]{index=10}

Ideal for track-day vehicles, tuned stage-2 builds, or anyone pushing their S55 engine hard, the CSF 8082 cools better and lasts longer than the factory cooler. For maximum charge-air efficiency, pair it with CSF's front-mount heat exchanger (#8075). Coverage confirmed through 2021; support beyond 2021 unverified.
