The 42mm 2-Row aluminum core is a massive improvement over the factory core. 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. 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 Focus RS 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
