CSF's high-performance all-aluminum radiator is a direct drop-in upgrade for the Scion FR-S, Toyota 86/GR86, and Subaru BRZ, 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 seam-brazes a B-shaped tube to raise heat-transfer surface area by roughly 15% over conventional round tubes. Ultra-efficient 6.5mm multi-louvered fins maximize airflow, and the radiator accepts all OEM components including the quick-connect hoses, AC condenser, mounting brackets, and fan shroud with no modifications.
