CSF 7239 Aluminum Radiator – Fits Ford Focus RS 2016-2018

Upgrade your Ford Focus RS with the CSF 7239 aluminum radiator designed for optimal cooling performance. Featuring a 42mm 2-Row aluminum core, this radiator significantly improves heat dissipation compared to the stock component. The thicker core, combined with a second cooling row and increased fluid capacity, enhances the system\'s ability to absorb and dissipate heat efficiently, making it ideal for track days or hot climates. CSF\'s exclusive B-Tube Technology boosts heat transfer by approximately 15%, ensuring your vehicle stays cooler under demanding conditions. Multi-louvered fins with 6.5mm height maximize airflow through the core, further improving cooling performance and engine reliability. This radiator is engineered as a direct replacement, offering a true plug-and-play \"Drop-in Fit\" with no modifications required for installation, although professional installation is recommended for optimal results. Constructed entirely from TIG-welded aluminum, it features CNC-machined mounting pins and brackets for precise fitment and durability. Each unit undergoes individual leak and pressure testing to ensure quality and reliability. With an OEM style inlet and outlet, this radiator maintains factory compatibility and performance standards. Backed by a 2-year limited warranty, the CSF 7239 radiator is an excellent upgrade for enthusiasts seeking improved thermal management and consistent vehicle performance in challenging Pass Flow Configuration allows coolant to flow across the core three times for lower outlet temperatures
