CSF 7056 Radiator (Left) for PORSCHE 911 Turbo (996/997) / 911 GT2 (996/997) / 911 GT3 (996)

With over fifty years of experience in radiator manufacturing, CSF is the clear choice when it comes to ensuring your Porsche 996/997 engine stays cool and performs at its peak. Designed for track or racing applications, this high-performance, all-aluminum radiator is a must-have for high-performance vehicles and race cars that require enhanced cooling efficiency in motorsport environments. This radiator features a 2-row core with CSF's exclusive "B-Tube" technology. Unlike standard "O-Tube" radiator tubes, CSF utilizes specially designed "B-Tube" tubes. These B-tubes are meticulously formed and then seam-soldered for sealing. CSF can use thinner, lighter aluminum material (with greater cooling efficiency) because this design is actually stronger than standard seam-welded O-tubes. The design (inlet opening in the middle of the tube, seam-soldered) increases the tube's heat exchange surface area by approximately 15% compared to standard tubes – the efficiency of two smaller tubes versus one larger tube under the same space constraints. With B-tubes, "dual-row laminar flow" can be achieved. CSF also employs highly efficient fin stock that is carefully and precisely aligned to maximize airflow through the radiator core. Fin pitch is carefully measured and calculated for each application and tested in a wind tunnel for maximum heat dissipation efficiency.

The CSF radiator for the Porsche 996/997 is a true "drop-in fit" design, requiring no modifications for installation. OE-style mounting brackets are CNC-machined and welded for maximum strength. The inlet/outlet connections are designed to match OEM specifications, allowing you to use OEM or aftermarket hoses. Trust the cooling experts at CSF for the most efficient, high-quality, and reliable radiators.
