Air Intake System Description for Chevrolet Chevy Suburban - 4WD 1998
The air intake system is used to direct 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. Refer to the appropriate service manual
for more information on the turbocharger.
