INTERNATIONAL CHARGE AIR COOLER: 2009 INT'L 5500I, 5600I, 5900I, 2007-2009 8600 TRANS STAR, 200

Boost the performance of your International / Navistar 2009 TransStar, ProStar, Eagle, or bus chassis with the American Radiator charge air cooler 2591600C91 with frame, built for heavy-duty reliability and maximum cooling efficiency. Designed with a rugged bar & plate aluminum core, this cooler outperforms traditional tube-and-fin designs by providing superior heat rejection under high-boost conditions. Lower intake air temperatures deliver denser airflow, promoting improved combustion, greater horsepower, and increased fuel economy across demanding duty cycles.

The frame-supported construction enhances structural strength, resists vibration fatigue, and ensures precise alignment with OEM mounting points. Built to exact factory specifications, this charge air cooler is a direct-fit replacement requiring no modifications for installation. Its corrosion-resistant materials and reinforced design stand up to thermal cycling, cracking, and long-term stress for extended service life.

Optimized airflow channels and expanded heat transfer surfaces stabilize intake temperatures, protecting critical components such as the turbocharger, intake piping, and engine from overheating damage. Engineered and tested to meet or exceed OEM standards, the American Radiator 2591600C91 bar & plate charge air cooler with frame is trusted by fleets and owner-operators for reliability, durability, and reduced downtime in the harshest operating conditions.
