Intake Air Distribution And Filtering

Intake Air Distribution and Filtering


3.7L

The air intake system consists of the:

- Air Cleaner (ACL) assembly.
- ACL outlet pipe.
- ACL element.
- 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.


3.5L Gasoline Turbocharged Direct Injection (GTDI)

The air intake system consists of the:

- Air Cleaner (ACL) assembly.
- ACL element.
- ACL outlet pipe.
- Charge Air Cooler (CAC).
- CAC pipes and tubes.
- Manifold Absolute Pressure (MAP) sensor.
- turbocharger intake pipe.
- turbocharger intake tubes.

The air intake system:

- cleans intake air with a replaceable, dry-type ACL element.
- measures manifold vacuum with a MAP sensor and converts it to an electronic signal. This provides the PCM information on the engine load.

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.

The CAC subsystem cools and increases the density of the compressed turbocharged air.
