Catalog cross-references come from manufacturer filter catalogs (Donaldson, WiX, Baldwin) and include OEM numbers that share the same catalog filter. Supersessions and aftermarket rows come from marketplace and supplier listings and are leads, not confirmed interchanges. Verify the exact part for your serial number before ordering.
