CSF Radiator for Mini Cooper S 2-Row Aluminum Core with B-Tube Technology

CSF Radiator for Mini Cooper S — 2-Row Aluminum Core with B-Tube Technology Upgrade cooling performance with CSF’s high-performance all-aluminum radiator engineered specifically for the Mini Cooper S. Backed by over five decades of radiator manufacturing expertise, this 2-row core unit delivers reliable street and track-capable cooling for high-horsepower builds and motorsport use. Key Features B-Tube Technology: Innovative "B"-shaped tubes brazed at the seam provide a stronger, lighter construction and increase heat-transfer surface area by ~15% over conventional oval tubes. Dual liquid laminar flow: The B-tube design creates the efficiency of two smaller tubes in the same space, improving circulation and thermal exchange. 2-Row aluminum core: Optimized balance of cooling capacity and compact fitment for the Mini Cooper S. Precision multi-louvered fins: Engineered and wind-tunnel tested fins maximize airflow and heat rejection for improved temperature control under load. Durable, lightweight construction: Thinner, high-efficiency aluminum reduces weight without sacrificing strength or reliability. Benefits Expect lower operating temps, increased consistency during spirited driving, and improved reliability for modified engines or competition vehicles. CSF’s advanced tube and fin engineering ensures superior heat dissipation while maintaining OE-compatible fitment and long-term durability. Perfect for: Mini Cooper S owners seeking a direct-fit performance radiator that performs on the street, track, or in high-demand driving conditions.
