CSF Aluminum Radiator - Black Series - 1 Row (08-21 WRX/STI)
HIGH EFFICIENCY CORE
CSF manufactures the most advanced and efficient radiator cores in the industry by using innovative tube and fin technologies with industry-leading testing methods to maximize airflow and heat dissipation. These techniques allow CSF to stay ahead of the pack when it comes to radiator technology.
B-TUBE TECHNOLOGY
Unlike a regular oval shape “O” type radiator tube, CSF uses a specially engineered tube in a 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 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.”
HIGH EFFICIENCY MULTI-LOUVERED FINS
CSF 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.
The Racing & High Performance Division of CSF Inc. strives to build and engineer the most advanced, efficient, and reliable cooling systems in the world. CSF manufacturers a wide variety of sophisticated cooling systems with more than 117 different applications ranging from high performance all-aluminum direct-fit replacement radiators, to complete custom applications for racecars, power sports, Off-road, marine, and industrial uses. All CSF cooling systems are designed and engineered to maintain optimal engine temperatures, even under the most extreme driving conditions.
