The intake air system provides clean air to the engine, optimizes airflow, and reduces unwanted induction noise. The intake air system consists of an air cleaner assembly, resonator assemblies and hoses. The main component of the air intake system is the air cleaner assembly. The air cleaner assembly houses the air cleaner element that removes potential engine contaminants, particularly abrasive types. Air induction resonators can be separate components or part of the intake air housing. The function of a resonator is to reduce induction noise. The air induction components are connected to each other and to the throttle body assembly with hoses.
If an engine maintenance procedure requires the temporary removal of the air cleaner, remove it; otherwise, never run the engine without it. The air filter should be replaced every 30,000 miles (50,000 km) under normal driving conditions.
Removal & Installation
Locate the air cleaner in the engine compartment. Inspect the flexible air intake ducting for cracks and tears. If the ducting is torn it should be replaced.
The air cleaner element may be replaced easily.
- Disengage the fasteners securing the top of the air cleaner.
- Carefully pull the air filter cover back to expose the element.
- Remove the air filter element.
- Wipe out the housing with a clean rag.
- Position the air filter element in the housing, make sure it seats properly.
- Install the air cleaner cover.
- Install the air cleaner fasteners, and tighten as necessary.
