PETERBILT | KENWORTH CHARGE AIR COOLER: 2008-2009 355, 2008-2011 365, 367, 2008-2010 T800

Improve the thermal efficiency of your Peterbilt 355 engine system with the American Radiator Bar & Plate Charge Air Cooler with Frame, crafted for heavy-duty cooling performance. Featuring a robust bar & plate aluminum core, this cooler delivers excellent heat rejection even under intense boost pressure. Lowering intake air temperatures helps produce denser charge air, which leads to stronger combustion, more horsepower, and better fuel economy.

The bar & plate design provides enhanced structural strength, vibration resistance, and thermal stability compared to older tube-and-fin cores. Combined with a reinforced frame, this cooler maintains precise alignment and offers exceptional durability, even under the rough road conditions faced by long-haul trucks.

Manufactured to OEM tolerances, the cooler installs as a direct-fit replacement, requiring no modifications—streamlining service and minimizing downtime. Its engineered airflow pathways and optimized core geometry help maintain thermal stability across long routes and heavy loads, protecting vital components like the turbocharger, intake piping, and engine from heat stress.

Backed by American Radiator’s reputation for quality and reliability, the Peterbilt 355 charge air cooler with bar & plate core and frame ensures dependable cooling, better longevity, and consistent performance—mile after mile.
