Baldwin Filters PA4428 Air Filter

The Baldwin Filters PA4428 is a panel-style automotive engine air filter designed as a direct replacement element. It fits vehicles that require this specific filter housing configuration for clean airflow.

Panel design fits existing housing

The panel construction slides into the factory air box without modifications or additional hardware. Its flat profile preserves the original intake layout and leaves surrounding engine bay space unaffected.

Sustained filtration over service interval

The filter media captures contaminants continuously throughout the recommended service life rather than only during initial use. Consistent airflow is maintained as the element loads with dust and debris over time.

Questions about this item

How often will the 13 9/16 in length need replacement under continuous engine operation?

Replace the panel filter at the interval specified by the vehicle manufacturer; the 13 9/16 in length determines housing fit, not service life.

Does the panel design restrict airflow or increase intake noise during all-day driving?

The panel design matches the original equipment airflow path; no additional intake noise or restriction is introduced when installed correctly.

What vehicle specifications must match the 5 11/32 in width and 2 25/32 in height for this filter to seal?

The air-box cavity must accept a panel 5 11/32 in wide by 2 25/32 in high; verify the housing dimensions before ordering.
