Product Overview

CSF has over 5 decades of experience manufacturing radiators. So when it comes to keeping your engine cool and your E9X M3 running at its best, a CSF High-Performance All-Aluminum Radiator is the obvious choice. Designed to perform on the street or at the track, a performance radiator is a must-have for both high horsepower builds as well as race vehicles which need added cooling performance in motorsports environments. The Triple-Pass Flow Structure allows the coolant to flow across the core of the radiator three times before exiting for lowest outlet temperatures possible. This radiator features a 2-Row core with CSF's exclusive B-Tube Technology: Unlike a regular oval shape "O" type radiator tube, CSF uses a specially engineered tube in the shape of a "B". These "B-tubes" are carefully formed and then brazed over the seam to seal. CSF is able to use thinner and lighter aluminum material (with better cooling efficiency) because this design is actually stronger than normal "O" shape tubes that are welded. The design (inlet in the middle of the tube that is seam brazed) increases the heat transfer surface area of the tubes by approximately 15% over regular tubes - producing the efficiency of two smaller tubes vs. one large tube within the same space criteria. With "B-tubes" you are able to get "dual liquid laminar flow". CSF also uses ultra efficient multi louvered fins that are carefully and 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 our wind-tunnel lab.

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.

Additional features of CSF racing radiators include:
• Finished with CSF's Show-Stopper mirror polish process
• CAD/CAM designed
• Racing-style aluminum drain plug
• Brazed in a controlled atmosphere brazing (CAB) furnace—the preferred process for aluminum
• ISO 9001/9002 certification
• Military-grade (special clad) aluminum used for tubes, fins, and headers
• Plates and side brackets meet JIS 3003 specifications
• Privately owned factories with full in-house tool rooms
• CNC-machined fittings
• TIG welded
