CSF S55 Top Mount Charge-Air-Cooler for 2015-2021 BMW M2/M3/M4 - 8082R

Fits 2015-2021 BMW M2 Competition, M2 CS, M3 Base, M4 Base, M4 CS, and M4 GTS models equipped with the S55 engine.

The BMW S55 engine is susceptible to heat soak, particularly during spirited driving or track sessions, resulting in significant power loss as intake temperatures climb. The CSF Top Mount Charge-Air-Cooler (MPN: 8082R) addresses this with a high-efficiency liquid-to-air core that is 60% larger than the factory unit. Unlike the OEM single-pass vertical-flow design, CSF utilizes a dual-pass, cross-flow configuration with two-stage water cooling to maximize thermal transfer and keep your intake temperatures low.

Built for durability and performance, this cooler features cast aluminum endtanks developed through 3D scanning and CFD analysis to ensure optimal airflow and a precise fit. Internal air dividers distribute charge air evenly across the core, maximizing the cooling surface area. This is a true drop-in replacement that uses factory-style quick-connect water fittings and integrated sensor ports for a seamless installation.
