The CSF 8179 is a high-performance auxiliary radiator for the side mounted coolers on B58 Supra and BMW G-Series cars. It uses a 2-row, 42mm core with CSF's B-Tube technology and 5mm tall multi-louvered "Track-Spec" fins in 100% aluminum TIG-welded construction, finished in a thermal black protective coating. A detachable aluminum rock guard, redesigned and wind tunnel tested to open more core area than the OEM plastic guard, is included. CNC machined brackets and OEM style quick connect fittings give a drop-in fit with no modifications. Sold individually; one unit fits either the left or right side, and two are required to replace both auxiliary radiators.
