CAC318 Air Charge Cooler for Kenworth and Peterbilt Trucks

The CAC318 air charge cooler (also known as a charge air cooler or intercooler) is designed for compatible Kenworth and Peterbilt heavy-duty truck applications. It helps reduce compressed intake air temperatures from the turbocharger before air enters the engine, supporting efficient combustion, airflow performance, and reliable engine operation.

A properly functioning charge air cooler is essential for maintaining power and performance in commercial trucks. When a cooler becomes damaged, clogged, or develops leaks, it can reduce boost efficiency, increase intake temperatures, and affect overall engine reliability.
