High-performance direct-replacement radiator for the A90/A91 GR Supra, BMW G29 Z4, and G20 3-Series. The 2-row 42mm aluminum core runs CSF's new 5mm multi-louvered fins and exclusive B-Tube technology, which raises heat transfer roughly 15% over conventional oval welded tubes for better cooling and faster recovery. It is fully TIG-welded all-aluminum with CNC-machined mounting brackets and OEM-style inlet/outlet, mounting in the factory location for a true plug-and-play install with no modifications. Each unit is individually leak and pressure tested and hand-polished to a mirror finish.
