CSF 7070 High Performance Radiator (Right) for PORSCHE 911 GT3 / GT3RS / Turbo S (991)

Part number7070

With over fifty years of experience in radiator manufacturing, CSF is the obvious choice when it comes to ensuring your Porsche 911 Carrera's engine cooling and performance at its peak. Designed for track or race applications, this high-performance, all-aluminum radiator is a must-have for both high-horsepower street cars and dedicated race cars requiring enhanced cooling for motorsport conditions. This radiator features a 2-row core with CSF's exclusive B-Tube technology: Unlike conventional "O" style oval radiator tubes, CSF utilizes specially designed "B" shaped tubes. These B-tubes are meticulously formed and then seam-soldered to seal them. CSF can use thinner, lighter aluminum material (with greater cooling efficiency) because this design is actually stronger than conventional "O" style welded tubes. The design (an inlet opening in the middle of the tube, seam-soldered shut) increases the surface area of the tubes' heat dissipation by approximately 15% compared to standard tubes – the efficiency of two smaller tubes compared to one larger tube within the same space criteria. With the B-tubes, a "dual-flow" liquid laminar flow effect can be achieved. CSF also utilizes ultra-efficient fin stocks that are carefully and precisely aligned to maximize airflow through the radiator core. Fin specs are carefully measured and calculated for each application and tested for maximum heat dissipation efficiency in a wind tunnel laboratory.

The CSF radiator for the Porsche 911 Carrera 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 the OEM connections, allowing you to use either OEM or aftermarket hoses. Trust the cooling experts at CSF for the most efficient, high-quality, and reliable radiators.
