CSF High-Performance All-Aluminum Radiator

Experience the excellence of CSF, a brand with over five decades of expertise in radiator manufacturing. When it comes to keeping your BMW 2 Series (F22/F23), BMW 3 Series (F30/F31/F34), or BMW 4 Series (F32/F33/F36) engine cool and running optimally, the CSF High-Performance All-Aluminum Radiator is the superior choice. Engineered for both street and track performance, this radiator is essential for high horsepower builds and race vehicles requiring additional cooling in motorsports environments.

Advanced B-Tube Technology

This radiator stands out with its exclusive B-Tube Technology, which offers superior strength and efficiency. Unlike conventional oval-shaped "O" type tubes, CSF's B-tubes are precision-engineered to maximize cooling performance. The unique "B" shape increases the heat transfer surface area by approximately 15% compared to regular tubes, effectively doubling the efficiency within the same space. This design allows for "dual liquid laminar flow," enhancing cooling capacity and ensuring optimal engine performance. Additionally, the use of thinner and lighter aluminum material, thanks to the B-tube design, provides better cooling efficiency without compromising structural integrity.

• Better Cooling Efficiency: The innovative B-tube design significantly increases heat transfer surface area, leading to improved cooling performance.
• Increased Strength: The B-tube construction is stronger than traditional "O" shape tubes, ensuring durability and reliability.

Maximized Airflow and Precision Engineering

CSF's commitment to excellence is further demonstrated by the ultra-efficient multi-louvered fins, which are meticulously aligned to maximize airflow through the radiator core. Each fin's specification is carefully measured and calculated for maximum heat rejection efficiency, tested in our wind-tunnel lab to ensure optimal performance. The combination of B-tube technology and precise fin design ensures that your vehicle maintains peak performance, whether on the road or at the track.

• Optimized Airflow: Multi-louvered fins enhance airflow, contributing to superior cooling efficiency.
• Professional Testing: Each radiator is tested in a wind-tunnel lab for maximum heat rejection efficiency.

With the CSF High-Performance All-Aluminum Radiator, you're not just buying a product; you're investing in the longevity and peak performance of your BMW vehicle. Choose CSF for unparalleled cooling solutions that stand the test of time.
