CSF brings over 5 decades of radiator manufacturing expertise to this high-performance all-aluminum solution for E9X, E8X, and E89 Z4 platforms. Engineered for both street and track environments, this radiator delivers superior cooling for stock and high-horsepower builds alike.
The radiator features a 2-Row 42mm core with CSF's proprietary B-Tube Technology, which uses specially engineered tubes brazed over the seam rather than welded. This design enables thinner, lighter aluminum material while maintaining greater strength than conventional O-tube designs. The B-tube configuration creates dual liquid laminar flow and increases heat transfer surface area by approximately 15% compared to traditional tubes.
