The CSF 7233 is an all-aluminum high-performance radiator for the 2023-2026 Toyota GR Corolla and 2020-2026 GR Yaris with the turbocharged 1.6L three-cylinder engine. It uses a 2-row 42mm core against the OEM single-row 27mm, with CSF's B-Tube Technology and 5mm track-spec multi-louvered fins for maximum surface area. It is 100 percent TIG-welded aluminum with aluminum end tanks, CNC-machined mounting brackets, a pre-plugged 1/8 inch NPT temperature sensor port, pre-installed foam sealing strips, and a hand-brushed satin finish. It is a drop-in fit with no modifications, and the end tanks are shaped to clear the CSF and Jackson Racing intercoolers.
