Air Intake System

The air intake system directs cool air from the exterior of the engine compartment to the intake manifold. An air cleaner is incorporated into the system to keep dirt from entering the engine. Some applications also have a PCM controlled turbocharger to increase power, improve driveability, and reduce emissions.
