The CSF 8285B is a high-performance stepped-core intercooler system for the 2023-2025 Toyota GR Corolla with the turbocharged 1.6L engine, developed with Jackson Racing. Its stepped core increases core volume by 45 percent and surface area by 73 percent over the OEM unit, with 15 cooling tubes against the OEM 9 and 16 fin rows against 10. The core steps from an 86mm thickness at the bottom to 40mm at the top, and the tanks are 100 percent TIG-welded aluminum. It includes 5-ply motorsport silicone hoses and bead-lock clamps, with the inlet and outlet upsized to 2.5 inches. It is a drop-in fit that connects to the factory charge pipes with minor trimming of the factory ducting, and does not include replacement charge pipes. The 2020-2025 GR Yaris fits with modifications. This is the black finish.
