Subaru WRX Radiator - CSF - High-Performance All-Aluminum - Satin Black - '22-'27. A direct-fit, drop-in upgrade engineered to keep your FA24-powered WRX cool during spirited driving, tuning, and track sessions.

CSF’s 2-row 42 mm core increases coolant volume by over 1 gallon (3.8 L), allowing the system to absorb and dissipate more heat under sustained load. Exclusive B-Tube Technology improves heat transfer by approximately 15% versus regular oval tubes, while ultra-efficient 6.5 mm multi-louvered fins maximize airflow through the core. The 100% TIG-welded all-aluminum construction with CNC-machined brackets and OEM-style inlet/outlet enhances strength and reliability. Each unit is individually leak and pressure tested and mounts in the factory location with no cutting required.
