What this part does
The Air Filter Box encloses the engine air filter and serves as the primary entry point for the cold air intake system. It protects the engine by ensuring only clean, filtered air reaches the combustion chambers and prevents water or road debris from entering the intake tract. If the housing cracks or the lid fails to seal correctly, unfiltered and unmetered air can bypass the mass airflow sensor, leading to rough idling, check engine lights, and accelerated internal engine wear.

Before you order
Verify that your current air box matches the PY1A133AX part number, as intake routing can vary slightly depending on the exact year and emission standard. Inspect the plastic mounting tabs on the bottom of the assembly, as these frequently snap off during removal or front-end impacts. This unit houses the filter but does not include a new filter element or the mass airflow sensor unless otherwise pictured. Ensure the metal retaining clips used to secure the upper lid are transferred from your old unit if they are missing.
