CSF
With over fifty years of experience in radiator manufacturing, CSF is the clear choice when it comes to keeping your MK4 VW engine cool and performing at its peak. Designed for track or race applications, this high-performance, all-aluminum radiator is a must-have for high-performance vehicles and race cars that require additional cooling efficiency in motorsport environments. This radiator features a 2-row core with CSF's exclusive B-Tube Technology: Unlike traditional O-tube radiator oval tubes, CSF uses specially designed B-tubes. These B-tubes are meticulously formed and then seam-soldered to seal them. CSF can utilize thinner, lighter aluminum material (with greater cooling efficiency) because this design is actually stronger than traditional O-tube welded tubes. The design (inlet opening in the middle of the tube, seam-soldered) increases the surface area of the tubes' heat exchange by approximately 15% compared to conventional tubes – the efficiency of two smaller tubes compared to one larger tube within the same space criteria. With B-tubes, "dual-laminar flow" can be achieved. CSF also utilizes highly efficient fin stocks that are carefully and precisely aligned to maximize airflow through the radiator core. Fin characteristics are meticulously measured and calculated for each application and tested in a wind tunnel for maximum heat dissipation efficiency.
The CSF MK4 VW Radiator 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 original equipment, allowing you to use OEM or aftermarket hoses. Trust the cooling experts at CSF for the most efficient, high-quality, and reliable radiators.
