CSF’s 42mm 2-Row aluminum core is a massive improvement over the factory core. The combination of a thicker core, second cooling row, and increased fluid capacity drastically improves the amount of heat the system can absorb and dissipate. CSF’s 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 cooling performance. All CSF Performance Radiators are 100% TIG-Welded All Aluminum construction which increases the overall strength of the radiator. This improves durability and longevity so you can be confident the CSF radiator will keep your Fiesta ST cool for a long time. - 2-Row – 42mm Ultra-High-Performance Core - Triple-Pass Flow Configuration Allows Coolant to Flow Across the Core Three Times Before Exiting for Lowest Outlet Temperatures Possible - 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 Pins and Brackets - 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 - 2-Year Limited Warranty
