CSF 96-04 Porsche Boxster S (986) / 98-05 Porsche 911 (996) Auxiliary Center Radiator

The CSF 7057 auxiliary center radiator uses CSF's exclusive B-tube technology, which increases the heat transfer surface area by about 15% compared to standard oval tubes. This design allows for a dual liquid laminar flow, making it more efficient at dissipating heat. It's a well-built, all-aluminum radiator designed to keep your 1999-2004 Porsche 911 or 2000-2004 Porsche Boxster running cool, whether you're on the street or the track.

This radiator features a 2-row, 42mm core with multi-louvered fins that are precisely aligned to maximize airflow. CSF carefully measures and tests these fin specifications for each application to ensure maximum heat rejection. The end tanks are 100% TIG-welded for durability, and the inlet and outlet connections are designed to match the original equipment, so you can reuse your factory hoses. It's a true drop-in fit, meaning no modifications are needed for installation, and it accepts the OEM AC condenser and fan shroud.

CSF has been making radiators for over 50 years, and this unit is built to perform. It's a solid option for replacing a worn-out original or for adding extra cooling capacity to a higher-horsepower build.
