The CSF high-performance all-aluminum radiator for 2008–2015 Subaru Impreza WRX/STI is a true drop-in upgrade that requires no modifications. Featuring CSF's 2-row core with exclusive B-Tube technology and multi-louvered fins, it increases heat transfer and airflow for street and track use. CNC-machined OE-style brackets, matching inlet/outlet locations, a black finish and individual leak testing make it a direct replacement for improved cooling.
