CSF's high-performance all-aluminum radiator is a direct drop-in upgrade for manual-transmission BMW 1 Series M, 135i, 335i, and Z4 models, built for street and track use on higher-horsepower and race builds. It runs a 2-row 42mm dual core using CSF's B-Tube technology, which raises heat-transfer surface area by roughly 15% over conventional round tubes, with 6.5mm multi-louvered fins for maximum airflow. The radiator accepts all OEM components including the quick-connect hoses, AC condenser, mounting brackets, and fan shroud with no modifications.
