The CSF all-aluminum auxiliary radiator for BMW F87 M2 and Gen 1 B58 applications is a high-performance drop-in cooler that mounts in the factory location using OEM quick connections. Its TIG-welded aluminum tanks, integrated mounting frame and satin-black finish improve strength and corrosion resistance. A 2-row, 42mm core with CSF's B-Tube technology and new 5mm fins increases heat dissipation, while detachable rock guards protect against debris. Sold individually, it’s intended to reduce coolant temperatures and improve recovery under aggressive driving.
