This is a genuine Fleetguard air filter element, part number AF25543K, in the original factory-labeled carton. The label reads ELEMENT, quantity 1, Made in U.S.A.
Fleetguard has been a benchmark name in heavy-duty filtration since 1958, supplying air, fuel, lube and hydraulic filtration for on-highway trucks, agricultural equipment, construction machinery and power generation.
This is an outer air element with fins. The fins impart a swirl to incoming air so heavier dust is thrown outward before it reaches the media — a built-in pre-cleaning stage that extends service life in dusty conditions.
It is the outer half of a two-stage air cleaner and is normally paired with a separate inner safety element.
