The CSF all-aluminum 2-row radiator for 2008–2021 Subaru WRX/STI is a drop-in replacement engineered for street and track cooling. CSF's B-Tube technology and multi-louvered fins increase heat transfer and airflow, while TIG-welded, all-aluminum construction and CNC-machined OE-style brackets provide durable, direct-fit installation. Inlet/outlet positions match OE so OEM hoses can be reused.
