Subaru WRX Radiator - CSF - All-Aluminum, 2-Row, 42mm Core with Exclusive B-Tube Technology - Satin Black (2022-2027). A direct-fit, stronger, higher-capacity replacement for the OE radiator.

The 42mm 2-row core adds over 1 gallon (3.8L) of coolant capacity to absorb and shed more heat under hard use or tuning. CSF's B-Tube design improves heat transfer by about 15% vs regular oval tubes, and multi-louvered 6.5mm fins keep air moving through the core. TIG-welded all-aluminum construction, CNC brackets, and OEM-style inlets/outlets provide durability and a factory install with no cutting. A smart choice when switching to a front-mount intercooler.
