# CSF 16-18 Ford Focus RS Radiator

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.

-   Triple Pass Flow Configuration Allows Coolant to Flow Across the Core Three Times Before Exiting for Lowest Outlet Temperatures Possible
-   6.5mm Tall Ultra Efficient Fins with a Multi-Louvered Design for Maximum Surface Area Contact
-   True Plug-and-Play "Drop-in Fit" Installation Requires Absolutely No Modifications
-   Cooling Tubes with CSF's Exclusive B-Tube Technology
