This is the left-side all-aluminum radiator from CSF for the Porsche 991.2 911 (Carrera, GT3/RS, GT2 RS) and 718 Boxster/Cayman (including GT4). It uses a 2-row, 42mm core built with CSF's exclusive B-Tube Technology for roughly 20% greater cooling efficiency than conventional tubes, paired with 6.5mm multi-louvered fins. The all-aluminum core has 100% TIG-welded end tanks and is a plug-and-play drop-in that accepts the OEM AC condenser and fan shroud with no modifications. Each unit is individually leak and pressure tested.
