The CSF S550 Ford Mustang 2.3L EcoBoost High-Performance All-Aluminum Radiator delivers exceptional cooling efficiency for both street-driven and track-focused vehicles. With more than five decades of engineering expertise, CSF designs radiators that outperform factory units and maintain stable engine temperatures even under high boost, spirited driving, or extreme heat.

This advanced cooling upgrade uses a 2-row 42mm high-performance core equipped with CSF’s exclusive B-Tube Technology. Unlike traditional “O”-shaped tubes, the precision-formed “B” shaped tubes offer increased strength and superior thermal efficiency. This design increases the internal heat transfer surface area by approximately 15%, enabling the performance of two smaller tubes within a single compact space. The result is improved coolant stability, enhanced flow, and significantly better heat dissipation.

To boost airflow efficiency, CSF integrates ultra-efficient multi-louvered fins with a 6.5mm fin height, engineered through extensive wind-tunnel testing for maximum heat rejection. These design enhancements make the radiator ideal for high-horsepower builds, tuned EcoBoost engines, or customers experiencing higher-than-normal coolant temperatures during performance driving.

Installation is simple thanks to the radiator’s true drop-in fitment. CNC-machined brackets, “quick-connect” inlet and outlet fittings, and OE-style connections allow seamless compatibility with the factory AC condenser, fan shroud, mounting brackets, and OEM or aftermarket hoses. Fully TIG-welded all-aluminum construction and an all-aluminum race-style drain plug add durability and longevity, topped off with a smooth satin finish for a clean performance look.
