Intake Air Distribution and Filtering

Intake Air Distribution and Filtering

The air intake system consists of the:

- Air Cleaner (ACL) inlet pipe.
- ACL assembly with element.
- ACL outlet pipe.
- intake air resonator assembly.
- Mass Air Flow (MAF) sensor.

The air intake system:

- cleans intake air with a replaceable, dry-type ACL element.
- measures airflow and air temperature with the MAF sensor.

The engine ACL contains an ACL element made of treated, pleated paper. A new ACL element must be installed periodically as scheduled. Engine performance and fuel economy are adversely affected when maximum restriction of the ACL element is reached.
