Anyone else using the extended version of the FL1A filter? It's Motorcraft p/n FL299 and corresponds to the following:
AC - PF42
Carquest - 85773
Fram - PH977A (not that anyone would use a Fram! :roll: )
Napa - 1773
Purolator - L40017
Wix - 51773
It's nearly 2" longer than a normal FL1A so it gives us some additional oil capacity. It will also be less susceptible to clogging/decreased flow as the miles rack up. Given the dimensions of the inline six, 99% of us have PLENTY of room for this larger filter w/o any clearance issues.
