The CSF auxiliary center all-aluminum radiator for 981 Cayman and Boxster models is a plug-and-play upgrade engineered for street and track cooling. It uses a 2-row 42mm core with CSF's B‑Tube technology and multi-louvered fins to increase surface area and airflow. CNC‑machined brackets, TIG‑welded end tanks and OEM-style inlet/outlet connections let you reuse OEM hoses and install without modifications.
