All-aluminum, TIG-welded high-performance radiator for the GR Corolla and GR Yaris, developed with race-team data as a true plug-and-play replacement for the factory unit. The 2-row, 42mm core uses CSF's exclusive B-Tube technology to raise heat transfer roughly 15% over conventional oval welded tubes, paired with new 5mm ultra-efficient multi-louvered fins for maximum surface area and airflow. The end tanks are designed with extra clearance for the CSF x Jackson Racing intercooler and other aftermarket intercoolers. CNC-machined mounting brackets, OEM-style inlet/outlet, pre-installed foam sealing strips, and a pre-plugged 1/8" NPT sensor port complete the drop-in fit.
