The CSF all-aluminum radiator for 2008–2015 Subaru WRX/STI includes a built-in oil cooler and a 2-row core tailored for street and track cooling demands. CSF's B-Tube technology increases tube surface area for better heat transfer while multi-louvered fins maximize airflow. CNC-machined fittings, OEM-style inlet/outlets and a drop-in fit make it suitable for upgraded cooling without modifying factory mounts or hoses.
