CSF's high-performance all-aluminum radiator is a plug-and-play drop-in for the Audi 4000, 80, 90, Coupe, and Quattro (B1/B2/B3/B4) 5-cylinder chassis, built for street and track use on high-horsepower and race builds. It uses a 2-row 42mm dual-pass core with CSF's exclusive B-Tube Technology, which raises heat-transfer surface area roughly 15 percent over standard tubes, plus 6.5mm multi-louvered fins for maximum airflow. A modular design supports use with or without the auxiliary radiator, with multiple fan-shroud mounting points and overflow-pipe locations for different model variations. Sensor ports are M22x1.5.
