At first glance the #7211 looks very similar to CSFs E36 M3 Radiator (#3054). While the overall shape is very similar, there are several key features that make the new swap radiator special. Because the S54 requires a much more robust oil cooling system than the E36s S52/S50, CSF made special provisions to fit two different race spec oil coolers. Please note, this radiator and oil cooler combination can be used for S50 & S52 Swaps as well. To do this, the height of the radiator was reduced slightly so the CSF race spec coolers can fit it in a factory style location. The radiator includes a custom designed oil cooler mounting bracket which has provisions to fit both oil coolers (CSF #8032 & #8240). In addition, a custom designed radiator cover plate allows for an optimized coolant overflow line placement which is concealed for an OEM+ appearance.CSF also includes brackets for an electric fan conversion. These brackets are designed to fit a single 16 inch SPAL Fan (not included). While it is possible to retain a clutch type fan, it is much easier to convert to an electric fan on top of the performance benefits.The 2-Row 42mm aluminum core offers the largest coolant capacity possible and incredible heat dissipation. CSFs Exclusive B-Tube Technology increases the heat transfer by approximately 15% over regular oval welded tubes. In addition, the super-efficient multi-louvered fins maximize airflow through the core for the best possible performance. All mounting brackets are CNC Machined for precise fitment. The cooling inlet/outlet connections use E36 OEM style slip on connections. 2-Row 42mm Core (Dual Core) Featuring CSFs Exclusive B-Tube Technology Core Features an Ultra-Efficient Fin with 6.5mm Fin Height and Multi-Louvered Design for Maximum Surface Area Contact CNC Machined Quick-Connect Inlet/Outlet Connections CNC Machined Brackets and Fittings for Superb Fit and Durability All-Aluminum Race Style Drain Plug 1-Hour Mirror Finish Hand Polish Drop-in Fit Requiring No Modifications to Install Accepts All Attaching OEM Components Including Quick Connect Hoses, AC Condenser, Mounting Brackets and Fan Shroud
