Automotive Air Filter Panel

The Baldwin Filters PA4439 is an automotive engine air filter built in a panel design for vehicle intake systems. It serves drivers and mechanics who need a direct-fit replacement element to maintain clean airflow. Buyers who require a different housing style or a non-automotive filtration solution should look elsewhere.

Dimensions and Fit

The filter measures 9 inches wide by 13 7/8 inches long with a height of 1 1/4 inches. These exact dimensions determine whether the element seats correctly in the factory air box. No additional hardware or sealing components are included in the package.

Build and Installation

The panel construction uses pleated media housed in a rigid frame that resists collapse under engine vacuum. Its flat profile allows straightforward insertion into the designated slot without tools. The design is intended for periodic replacement following the vehicle manufacturer's service intervals.

Questions about this item

How often should I replace the PA4439 air filter panel?

Replace the panel at the vehicle manufacturer's recommended service interval or sooner if it appears dirty or damaged during inspection.

What is the first limit I will hit when running the engine hard with this filter?

The filter's airflow capacity will become the limiting factor before the media reaches its dust-holding maximum.

Does the PA4439 add noticeable noise or heat when the engine runs all day?

The panel is a passive component; it adds no mechanical noise and does not generate heat, only a slight, normal intake restriction.
