Baldwin Filters PA4166 Air Filter

The Baldwin Filters PA4166 is an automotive engine air filter built with a round element design. It fits vehicles that require a round filter with a 5-1/2 inch outside diameter and a 3-9/32 inch height. The filter is sold as a complete unit, not as an element-only replacement.

Round element upgrade for older housings

This filter replaces flat-panel or oval filters only when the air-box is designed for a round 5-1/2 inch seal. The jump is worth it when the original housing matches these exact dimensions and the service interval calls for a full-element change.

Drop-in installation with seal check

Installation consists of opening the air-box, removing the old filter and seating the new unit so the outer diameter seats evenly. What usually goes wrong is a cocked lid that pinches the media or leaves a gap, letting unfiltered air bypass the element.
