CSF racing radiators feature the most advanced and efficient radiator cores in the industry. Offered for both vehicle-specific and universal applications, they use innovative tube and fin technologies with industry-leading testing methods to maximize airflow and heat dissipation.

Specially engineered tubes in the shape of a "B" are carefully formed and then brazed over the seam. CSF is able to use thinner and lighter aluminum because this design is stronger than normal welded "O" shape tubes. With the inlet in the middle of a seam-brazed tube, the surface area of the tubes is increased approximately 15 percent over regular tubes. With CSF's B-tubes you get dual liquid laminar flow and the efficiency of two smaller tubes vs. one large tube in the same space.

High-efficiency, multi-louvered fins are precisely aligned to maximize airflow through each radiator core. Fin specifications are carefully measured and calculated for each application, and tested for maximum heat rejection efficiency in CSF's wind-tunnel lab.

CSF offers two all-aluminum end-tank designs to match any style and performance needs. CSF 7000 Series racing radiators have OE-style radial tanks that are flat, rounded, and welded together. Perfect for the customer who likes the sleek and smooth look, and wants to display the intricate welding.

CSF deep-drawn end tanks are stamped to the same geometry of OE plastic end tanks. The only high performance manufacture to feature this advanced radiator technology; CSF deep-drawn end tanks feature less welding, and are generally considered the strongest tanks in the industry.
