U.S. government catalog cross-reference
The U.S. Defense Logistics Agency catalogs these part numbers under one National Stock Number, NSN 2940-00-885-3336 (filter element, intake air cleaner), meaning the government buys them as the same item of supply:
| Brand | Part number | How the government lists it |
|---|---|---|
| Baldwin | PA1633 | primary number |
| WIX | 42120 | primary number |
| WIX | DT3120 | also listed as |
Baldwin's 2024 catalog also lists this cross.

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.
