CSF High-Performance All-Aluminum Radiator - Ford Focus RS (2016-2018) - 7239
Keep your 2.3L EcoBoost engine running cool under extreme track conditions and high-horsepower demands with the CSF High-Performance All-Aluminum Radiator (7239) for the 2016-2018 Ford Focus RS. While the factory Focus RS is well-engineered, hard driving, hot climates, and power modifications can easily overwhelm the stock plastic-tank single-row radiator. CSF's upgraded all-aluminum solution delivers superior heat rejection and unmatched durability.
Engineered with a massive 42mm 2-row core and CSF's exclusive B-Tube Technology—which increases heat transfer surface area by approximately 15% over standard oval tubes—this radiator maximizes fluid efficiency and thermal dissipation. Combined with ultra-efficient multi-louvered fins, 100% TIG-welded all-aluminum construction, and an advanced triple-pass coolant routing design, it drastically lowers coolant temperatures and eliminates hotspots. Designed as a true drop-in fit using CNC-machined OE-style mounting brackets, it installs seamlessly without modifications.
