CSF GR Corolla High-Performance Radiator

CSF designed this high-performance all-aluminum radiator as a drop-in cooling upgrade for the 2023+ Toyota GR Corolla and 2020+ Toyota GR Yaris. The factory radiator uses plastic tanks and a single-row aluminum core; the CSF replacement uses a larger 2-row, 42mm aluminum core to increase coolant capacity, improve heat dissipation, and recover faster under hard street or track use. CSF's B-Tube technology increases heat transfer surface area compared with standard oval tubes, while multi-louvered 5mm fins help maximize airflow through the core. The TIG-welded aluminum construction is built for durability, with CNC-machined mounting brackets, OEM-style inlet and outlet connections, pre-installed sealing foam, and a pre-plugged 1/8in NPT temperature sensor port.
