CSF High-Performance all-aluminum radiator for the 2013-2018 Ford Focus ST. Its 31mm aluminum core is a thick upgrade over the factory unit, increasing fluid capacity and the amount of heat the system can absorb and dissipate. A triple-pass flow configuration runs coolant across the core three times for the lowest possible outlet temperatures, while exclusive B-Tube technology adds roughly 15% heat transfer over standard oval tubes and 6.5mm multi-louvered fins maximize airflow. TIG-welded all-aluminum construction with CNC-machined mounting pins and brackets and OEM-style inlet/outlet makes it a true plug-and-play drop-in.
