Baldwin PA2221 automotive air filter

This Baldwin Filters PA2221 is an automotive engine air filter designed as a panel element for vehicle intake systems. It serves owners and technicians replacing the factory filter during scheduled maintenance. The part fits applications that require this exact panel configuration.

Panel dimensions 8-1/2 by 1-5/8 inches

The critical specification is the panel size of 8-1/2 inches in both width and length with a height of 1-5/8 inches. These three measurements determine whether the filter seats correctly in the air-box. Verify the housing dimensions before ordering.

Simple drop-in replacement

Installation consists of opening the air-box, removing the old panel and inserting the new one with the same orientation. The most common issue is ordering the wrong panel size, which prevents a proper seal and allows unfiltered air into the engine.

Questions about this item

How does the 8-1/2 x 1-5/8 in panel size affect airflow in my engine?

The panel dimensions match the original equipment opening, so the filter seals against the housing without gaps that let unfiltered air bypass the element.

What mounting standard does the PA2221 use to fit the air box?

It drops into the factory air-box slot with no clips, brackets or adhesive required; the panel edges sit flush against the housing rails.

What clearance do I need around the 1-5/8 in height when installing the filter?

Allow at least the full 1-5/8 in vertical space inside the air-box lid so the panel seats flat without compressing the pleats or fouling the cover latch.
