CAC322 Air Charge Cooler for Kenworth and Peterbilt Trucks

The CAC322 air charge cooler (also known as a charge air cooler or intercooler) is designed for compatible Kenworth and Peterbilt heavy-duty trucks. It reduces compressed intake air temperatures from the turbocharger before air enters the engine, helping maintain proper airflow, combustion efficiency, and reliable engine performance.

For commercial trucks operating under demanding conditions, a reliable charge air cooling system is essential. A damaged or leaking air charge cooler can reduce boost efficiency, increase intake temperatures, and affect overall engine reliability.
