CSF 2020+ Toyota A90/A91 GR Supra / 2019+ BMW Z4 (2.0/3.0L) / 19-21 BMW G2X All-Aluminum Radiator

The latest 5mm fin technology in this CSF radiator means a significantly increased heat exchange surface area. This updated design helps improve overall cooling efficiency and allows for faster temperature recovery, especially important when you're pushing your 2019+ BMW Z4 or 2020+ Toyota Supra harder. The core itself is a 2-Row, 42mm aluminum design, which not only holds more coolant but also dissipates heat much better than the stock unit. CSF's exclusive B-Tube technology further boosts heat transfer by about 15% compared to standard oval tubes, and the multi-louvered fins are designed to maximize airflow right through the core.

Built entirely from aluminum with TIG-welded seams, this radiator offers improved strength and durability for demanding conditions. It's designed as a direct replacement, meaning it fits right into the factory location without needing any modifications. This is crucial for vehicles like the A90/A91 Supra and BMW G2X models, where bigger turbos and increased power output can overwhelm the stock radiator, potentially leading to overheating or limp mode. CSF has extensive experience with B58 cooling systems, drawing on feedback from race teams and development partners to refine this design.

This radiator has been tested in various motorsport environments, including drag racing with Titan Motorsports and road racing with Studio RSR. While prototypes used 6.5mm fins, the final production version incorporates the even more efficient 5mm fin technology for maximum thermal performance. It's a solid option for anyone looking to upgrade their cooling system for spirited driving or track use, ensuring your engine stays cool and performs reliably.
