What this part does

The air filter box encloses the engine's air filter element, protecting it from dirt, moisture, and excessive engine bay heat. It routes incoming ambient air from the front intakes through the filter media before it reaches the mass airflow sensor and turbochargers. If this housing is cracked, warped, or missing its mounting clips, it can allow unmetered and unfiltered air to bypass the filter entirely. This condition often triggers check engine lights related to airflow metrics and can cause accelerated wear on internal engine components due to particulate ingestion.

Before you order

Verify whether you need the driver or passenger side housing, as the 4.4L V8 engine utilizes dual air filter boxes that are side-specific and not interchangeable. Inspect your original lower housing and lid to ensure the mounting points and sensor provisions match this replacement. You will need to transfer your existing mass airflow sensor and install a fresh filter element, as used housings are supplied bare unless otherwise noted.
