With over fifty years of experience in radiator manufacturing, CSF is the obvious choice when it comes to keeping your Subaru WRX/STI engine cool and performing at its peak. Designed for track or race applications, this high-performance, all-aluminum radiator is a must-have for both high-horsepower 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 conventional "O" style oval radiator tubes, CSF uses specially engineered "B" style tubes. These B-tubes are carefully 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 "O" style seam-soldered 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 under the same space constraints. With B-tubes, "dual-row laminar flow" can be achieved. CSF also utilizes highly efficient fin plates that are carefully and precisely 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 Radiator for Subaru WRX/STI 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 ports are designed to match the OEM ports, so you can use OEM or aftermarket hoses. Trust the cooling experts at CSF for the most efficient, high-quality, and reliable radiators.
