CSF Fits 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. The Focus RS was very well engineered and performed admirably out of the box. However, a few upgrades can quickly lead to heat issues, especially on the track or in hot climates. An upgraded radiator from CSF is the perfect solution. The CSF #7239 Cooling product is designed to be a \"Drop-In Fit\" application. The product will install in the OEM Location with no modifications necessary unless otherwise noted or instructions are included in the product package. Please see the manufacturer repair manual for standard installation instructions. If you do not feel confident installing this product CSF recommends taking it to a qualified installation facility.
