CSF
With over fifty years of experience in radiator manufacturing, CSF is the obvious choice when it comes to keeping your MK4 VW's 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-output vehicles and race cars that require enhanced cooling efficiency in motorsports environments. This radiator features a 2-row core with CSF's exclusive B-Tube Technology: Unlike conventional O-shaped radiator tubes, CSF utilizes specially engineered B-shaped tubes. These B-tubes are meticulously formed and seam-soldered to seal them. CSF can use thinner, lighter aluminum material (with greater cooling efficiency) because this design is actually stronger than conventional seam-welded O-tubes. The design (inlet opening in the middle of the tube, seam-soldered) increases the surface area of the tubes by approximately 15% compared to conventional tubes – the efficiency of two smaller tubes compared to one larger tube under the same space constraints. With B-tubes, "dual-laminar flow" can be achieved. CSF also utilizes highly efficient louvered fins that are precisely and accurately aligned to maximize airflow through the radiator core. Fin characteristics are carefully measured and calculated for each application and tested for maximum heat dissipation efficiency in a wind tunnel laboratory.
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. 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.
