Description

CSF has over 5 decades of experience manufacturing radiators. So when it comes to keeping your engine cool and your Audi Quattro/B1/B2/B3/B4 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. 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 manufactures the most advanced and efficient radiator in the industry for your Audi Quattro/B1/B2/B3/B4. CSF uses innovative tube and fin technologies with industry-leading testing methods to maximize airflow and heat dissipation.
The CSF #7208 Cooling product is designed to be a “Drop-In Fit” application. The product will install in the OEM Location with no modifications necessary unless otherwise noted or instructions are included in the product package.
