OK. I know where I need to go at Ford to get the exact specs, so I will have to work on that now. I know the exact catalog and the page even. That and some more information was possible due to a very nice and informative gentleman at Purolator talking with me for about 15 minutes on the phone today. Purolator has been nothing but stellar in their communication and service with me about all of this! Kudos!
I'm reposting the information I found about the FL1A to help clarify what I'm about to type:
Quote:
FL1A
Oil Filter Style Canister
Height (in) 5.190 in.
Outside Diameter (in) 3.780 in.
Filter Bypass Relief Valve Yes
Relief Valve Open (psi) 11-14 psi
Anti-Drainback Valve Yes
Smallest Particle Filtered 20 microns
Maximum Burst Pressure (psi) 200 psi
Thread Size 3/4-16 in.
Gasket Outside Diameter (in) 2.800 in.
Gasket Inside Diameter (in) 2.422 in.
Gasket Thickness (in) 0.203 in.
Some brief, overall facts about the Motorcraft gasoline engine oil filters:
The ratings such as the filtering efficiency (80% at 20 microns) and the 200psi burst pressure are simply the absolute minimum that Ford will allow.
Taking the FL1A as an example:

Some brief, overall facts about the Motorcraft gasoline engine oil filters:
The ratings such as the filtering efficiency (80% at 20 microns) and the 200psi burst pressure are simply the absolute minimum that Ford will allow.
Taking the FL1A as an example:
- The actual filtering efficiency should be ~93% at 20 microns.
- The canister can also actually withstand a burst pressure of somewhere about/up to ~280psi.
- The holding capacity should be ~12g.
- The Motorcraft filters are somewhere in between a Purolator Classic and a PureOne.
- The "S" type filters, such as the FL-820S, are like the PureOne filters in that they both have a silicone ADBV.
- The "non-S" type filters, such as the FL1A, are like the Classic in that they do not have a silicone ADBV (providing the equivalent Motorcraft filter model has one).
- The Purolator filters have a dome-end bypass valve vs. the Ford-spec'd...end? bypass valve (the correct name is slipping me at the moment).
