Baldwin Filters PA2861 Inner Air Filter

This Baldwin Filters PA2861 is an automotive engine inner air filter with a round design. It functions as the secondary filtration stage inside a dual-element housing to protect the engine from fine contaminants. The filter measures 2 7/16 inches in outside diameter and 9 1/8 inches in height. It is supplied new and ready for installation.

Suits Diesel Engines With Round Inner Elements

This part suits maintenance on diesel equipment requiring a round inner air filter with these specific dimensions. It is not for applications using a panel-style or oval inner element. Buyers who need an outer primary filter or a complete housing assembly should look at other components. The item is restricted from sale in certain states.

Critical Dimensions Are 2 7/16 Inch Diameter By 9

The single specification that decides fitment is the physical size: an outside diameter of 2 7/16 inches and a height of 9 1/8 inches. These measurements must match the air cleaner housing exactly. Verify the housing dimensions before ordering to ensure correct sealing and filtration performance.

Questions about this item

How does the 2861 model number help me confirm this inner air filter fits my engine?

The 2861 model number is the Baldwin Filters part reference; match it to your vehicle manufacturer's cross-reference list or service manual to verify fitment for your specific engine application.

What does the round design with a 2-7/16 inch outside diameter mean for installation in the air cleaner housing?

The round element with a 2-7/16 inch outside diameter seats directly inside the compatible air cleaner housing; ensure your housing accepts this diameter and the 9-1/8 inch height before ordering.

What physical clearance do I need in the air cleaner canister for the 9-1/8 inch height of this inner filter?

You need at least 9-1/8 inches of clear vertical space inside the air cleaner canister so the inner filter element can seat fully without binding against the cover or outer filter.
