The CSF radiator features a 1-Row 31mm aluminum core that not only increases the fluid capacity of the radiator, but also improves the cores ability to dissipate heat. CSF went through several different prototypes using cores of varying thicknesses. The 31mm core was found to be the best balance of performance and fitment. This sizing allows for use of an OE style clutch pull fan or an aftermarket electric push fan. CSF’s Exclusive B-Tube Technology increases the heat transfer by approximately 15% over regular oval welded tubes. With nearly double the number of cooling fins and tubes, the CSF Radiator will outperform the OEM unit by a significant margin. In addition, the super-efficient multi-louvered fins maximize airflow through the core for the best possible performance. The radiator mounts in the factory location and requires no modifications or cutting. The TIG-Welded 100% All Aluminum construction increases the overall strength of the radiator. This improves durability and longevity so you can be confident the CSF radiator will keep your BMW cool for a long time. - 2-Row, 42mm Ultra-High-Performance Dual Pass Core - Cooling Tubes with CSF’s Exclusive B-Tube Technology - 6.5mm Tall Ultra Efficient Fins with a Multi-Louvered Design for Maximum Surface Area Contact - CNC Machined Mounting Brackets and OEM Style Inlet/Outlet - 100% All Aluminum TIG-Welded Construction - True Plug-and-Play “Drop-in Fit” Installation Requires Absolutely No Modifications - Individually Leak and Pressure Tested - Includes optional / removable mounting brackets to run aftermarket 11” SPAL fan #30100365 - Requires use of lower radiator coolant hose BMW: 11 53 1 250 702 - Compatible with vehicles equipped with and without Air Conditioning - M12X1.5P Temperature Switch Sensor Port & Plug - 2-Year Limited Warranty
