BMW M4 Front Mount Heat Exchanger by CSF (2021–2027). Polished aluminum upgrade featuring a 2-row 42mm B-Tube core and included black rock guards.

The larger 2-row core and revised tanks raise volume to absorb and shed more heat, helping lower IATs with quicker heat-soak recovery. CSF’s 6.5mm multi-louvered fins also improve airflow to the radiator behind the exchanger. Built from 100% TIG-welded aluminum with CNC-machined brackets and OEM-style quick-connects for a true drop-in fit. Package includes upper and lower rock guards and a transmission cooler mounting kit for ZF8 cars. Tested by CSF’s R&D partners and backed by a 2-year limited warranty.
