Fleetguard MK11666 cross reference

Baldwin lists BK6579 as the replacement for MK11666.

Source: Baldwin Manufacturers' Cross-Reference, Form 560-24 (2024). MK11666 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.
