CSF 7208 High-Performance 2-Row Dual Pass Aluminum Radiator for Select 1980-1992 Audi (5-Cylinder)

The CSF 7208 is a high-performance, all-aluminum radiator engineered for classic Audi small-chassis platforms (B1-B4). Fits select 1980-1992 Audi 4000, 80, 90, Coupe GT, and Quattro (5-Cylinder). Designed for high-horsepower street builds and competitive motorsports, this radiator replaces the aging factory unit with a 42mm, 2-row dual-pass core for superior thermal management.

This radiator utilizes CSF's exclusive B-Tube technology. Unlike standard oval "O" type tubes, the B-Tube is seam-brazed to increase heat transfer surface area by approximately 15%, providing the cooling efficiency of two smaller tubes within the same space. Paired with 6.5mm multi-louvered fins, the design maximizes airflow and heat rejection. The TIG-welded construction and satin black finish provide a durable, OEM+ aesthetic that installs with no modifications required.
