Built for Porsche Cooling Demands

CSF part number 7057 is engineered as a direct-fit center radiator for the Porsche 996 Carrera / GT3 / GT3 RS / 986 Boxster platform. The aluminum construction, 1.625-inch core thickness, and 22.4375-inch core height support efficient heat rejection in demanding driving conditions. This radiator uses a cross-flow layout with top-right inlet and top-left outlet locations, and it mounts with OE hardware for a clean replacement path. If you are searching for a Porsche 996 center radiator or a Porsche 986 Boxster all-aluminum radiator, CSF 7057 is built for that application.

CSF has more than five decades of radiator manufacturing experience, and this design reflects that background with brazed B-tubes, precise fin alignment, and OE-style fitment. The result is a performance radiator intended for drivers who want a direct replacement without modifying the vehicle. Part number 7057 also cross-references 996 106 037 50 and 996 106 037 51 for the same application.
