CSF top-mount charge-air-cooler for the S55-powered BMW F80 M3, F82/F83 M4 and F87 M2 Competition, the world's first cast-end-tank top-mount CAC for this engine, finished in raw aluminum. The S55 suffers from heat soak that drops power across consecutive dyno or track pulls; CSF's core is 60% larger than the OEM unit for far greater heat transfer from the turbo charge air. A left/right cross-flow dual-pass core with 2-stage water cooling replaces the OEM single-pass vertical-flow design and pairs with CSF's front-mount heat exchanger to keep intake temps down. Drop-in plug-and-play fit with OEM-style quick-connect water connections and sensor ports. Lifetime warranty.
