Baldwin Filters PA2231 Automotive Air Filter

The Baldwin Filters PA2231 is a panel-type automotive engine air filter designed to fit specific engine air boxes. It serves vehicle owners and technicians who need a direct-fit replacement element for scheduled maintenance. The filter uses a panel element construction without additional housing components.

Upgrade from clogged or damaged original equipment

This filter replaces a restricted factory element that reduces airflow to the engine. The jump is worth it when the current filter shows visible contamination, has exceeded the service interval, or causes a measurable drop in fuel economy. It restores the intended air volume for the engine management system.

Practical limits of panel element sealing

The panel design relies on a precise perimeter seal inside the OEM air box. Any warping of the housing or debris on the sealing surface will bypass filtration. The element cannot compensate for a cracked housing or missing fasteners. Installation requires a clean, undamaged sealing flange to function as specified.
