Introducing the Subaru WRX Radiator from CSF - High-Performance Aluminum with B-Tube Technology - `15-`21. Designed with over 50 years of CSF's innovation, this aftermarket radiator is made to handle the rigorous demands of both high-performance street use and competitive track environments.

The CSF WRX Radiator is the ultimate solution for improving your vehicle's cooling efficiency. Engineered for race-level performance, this radiator features a 2-row core equipped with CSF's patented B-Tube Technology. By swapping the traditional "O" shaped tubes for the uniquely strong and lightweight "B" tubes, CSF increases heat transfer surface area by about 15%. This design allows for "dual liquid laminar flow", boosting overall cooling efficiency. Ultra-efficient multi-louvered fins further enhance airflow, tested meticulously for maximum heat rejection in a wind-tunnel lab.
