CSF Aluminium Radiator - BMW 1M / 135i (E8X) / 335i (E9X) / Z4 (E89) - Automatic
The CSF Aluminium Radiator is an all-aluminium upgrade for automatic-transmission versions of the 2008-2011 BMW 135i (E8X), the 2007-2011 335i (E9X) and the Z4 (E89), and CSF also lists the 1M (E82). Its 42 mm two-row core uses CSF's seam-brazed B-Tube design, which is stronger than a welded oval tube and gives about 15% more heat transfer surface, together with 6.5 mm multi-louvred fins. The extra capacity helps keep temperatures under control in higher-powered builds and on track. It installs in the factory location with CNC-machined OE-style brackets, quick-connect inlet and outlet fittings for the factory or aftermarket hoses, and an aluminium race-style drain plug.
