CSF Radiator for Evo 7/8/9 High-Performance All-Aluminum 2-Row Core B-Tube

CSF Radiator for Evo 7/8/9 — High-Performance All-Aluminum 2-Row Core B-Tube Upgrade cooling for street or track: CSF brings over 50 years of radiator engineering to the Evo 7/8/9 with a purpose-built, all-aluminum 2-row core designed for high-horsepower builds and motorsports use. Key Features B-Tube Technology: Patented "B" shaped tubes brazed at the seam for enhanced strength and increased heat transfer surface area (≈15% more than standard tubes). Dual Liquid Laminar Flow: B-tubes enable dual-flow dynamics inside the same footprint, improving cooling efficiency compared to single large tubes. Ultra-Efficient Multi-Louvered Fins: Precisely aligned fins maximize airflow and heat rejection; fin geometry is application-specific and wind-tunnel validated. Lightweight, Durable Construction: Thinner, lighter aluminum is used without sacrificing strength thanks to the brazed B-tube design. Street and Track Ready: Engineered for daily-driven vehicles and competition cars that demand consistent cooling under extreme conditions. Why Choose CSF CSF’s combination of advanced tube geometry, optimized fin design, and decades of testing delivers reliable temperature control, reduced risk of overheating, and improved engine performance longevity for Evo 7/8/9 owners.
