CSF 2014+ BMW M3/M4 (F8X) Top Mount Charge-Air-Cooler - Raw Finish

The S55 engine in your F8X M3, M4, or M2 Competition is known to experience heat soak, especially after repeated hard runs on the track or dyno. This means you can see a noticeable drop in power as the engine struggles to cool the intake air. This top mount charge-air-cooler from CSF is designed to combat that issue directly. It features a core that's 60% larger than the factory unit, giving it a much greater capacity to pull heat away from the air coming from your turbos.

This cooler utilizes a dual-pass, cross-flow core configuration with two stages of water cooling, which is a significant improvement over the OEM's single-pass, vertical-flow design. This advanced design, refined with CFD analysis, helps maximize efficiency and reduce intake temperatures. The end tanks are cast with multiple air dividers to optimize airflow through the custom core. CSF also used 3D scanning and rapid prototyping to ensure a precise fit and make the most of the available space. Installation is designed to be straightforward, with a plug-and-play approach using OEM-style quick-connect water fittings and sensor ports.

This particular model, the 8082R, comes in a raw aluminum finish, with options for custom powder-coating available. When paired with a CSF Front Mount Heat Exchanger, this system works together to keep your BMW's intake temperatures down and its power output consistent, even under demanding conditions. It's a well-built solution for drivers who push their cars hard and want to maintain peak performance.
