The CSF Aluminium Radiator is a high-performance, all-aluminium replacement for the 1997-2002 Audi S4 (B5). It has a 42 mm two-row core with CSF's B-Tube technology, a seam-brazed tube that is stronger than a welded oval tube and adds about 15% more heat transfer surface, paired with 6.5 mm multi-louvred fins. The extra cooling capacity suits higher-powered builds and cars that see track use. It is a drop-in fit with CNC-machined OE-style brackets, quick-connect inlet and outlet fittings that take the factory or aftermarket hoses, and an aluminium race-style drain plug.
