Center-mount CSF High-Performance all-aluminum radiator for the Porsche 911 (991) Turbo, Turbo S, GT2 RS, GT3, GT3 RS, R, and Speedster, plus the 718 Cayman GT4/GTS and Boxster Spyder/GTS. It uses a 2-row 42mm core with CSF's exclusive B-Tube technology for roughly 20% more cooling efficiency than conventional tubes, with multi-louvered fins at a 6.5mm fin height to maximize airflow. The all-aluminum build has 100% TIG-welded end tanks, OEM-style machined inlet/outlet connections, and CNC-machined brackets, and it's a plug-and-play drop-in that accepts the OEM AC condenser and fan shroud. Each unit is individually leak and pressure tested.
