Baldwin's 2024 catalog lists PA2456XP as the replacement for AF4090 (Baldwin upgrade note).

Source: Baldwin Manufacturers' Cross-Reference, Form 560-24 (2024). AF4090 is newer than Fleetguard's last published cross-reference index (2012), so no Fleetguard-published crosses are shown.

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.
