All-aluminum auxiliary center radiator for the 1999-2004 Porsche 911 (996) Carrera and Carrera 4 and the 2000-2004 Boxster/Boxster S (986). It uses a 2-row 42mm core with CSF's exclusive B-Tube technology for roughly 20% more cooling efficiency, plus 6.5mm-tall multi-louvered fins. The all-aluminum build has 100% TIG-welded end tanks, CNC-machined brackets, and OEM-style inlet/outlet connections, and is a plug-and-play drop-in that accepts the OEM AC condenser and fan shroud. Each unit is individually leak and pressure tested.
