    U.S. government catalog cross-reference

    The U.S. Defense Logistics Agency catalogs these part numbers under one National Stock Number, NSN 2940-00-459-7250 (filter element, intake air cleaner), meaning the government buys them as the same item of supply:

    BrandPart numberHow the government lists it
    BaldwinPA1669primary number
    WIX42045primary number
    WIXDT9045also listed as

    Baldwin's 2024 catalog also lists this cross.

    Source: DLA PUB LOG Master Cross-Reference Data, October 2026 edition. Page last updated October 24, 2026.

    A shared NSN means the U.S. government buys these numbers as the same item of supply. Always verify fit for your truck before ordering.

    Upgrade chains run one way: equipment spec'd with a newer filter number should not step back to the older one. Go by what the truck was spec'd with.

    Always verify against the current OEM catalog before ordering. Cross references are a starting point, not a guarantee of fit.
