Are these filters (Ford Racing CM-6731-FL820) over-sized vs the MC fl-820S or are they exactly the same size? Also are they any good?

They're the same size. I heard they're the same filter internally, just a higher burst rating on the can, although I haven't cut one open.
I asked the same question a couple of years ago and the answer, from some members more knowledgeable than I, was that it's a good filter, but not worth the extra cost compared to the standard MC FL820S, especially for a street vehicle...unless you have crazy high oil pressure.

I think it might have a different filter media in it also. Seems I read that somewhere, but not sure since I've never cut one open. RF is correct about the burst rate, the metal in the can is a lot thicker than a regular filter.
There is/was significantly more media in the Ford Racing filter.

The new FL-820S may be shorter, but they have more media to make up for it. I don't know if the Ford Racing filter has been shortened or not.

Does the MC fl820S or the Ford Racing filter have a base end or dome end bypass? TIA
Both use base end.
I just sent them an email asking for detailed technical data on this filter. kekeke.
Data is in.

That's some awesome flow. Good efficiency, too. Too bad they cost 4x as much as a regular 820S.

Yes, impressive performance specs for sure. Great filtering efficiency and great flow.
I wish a data sheet like this was available for all filters ... it would be easy to see the good vs bad filters in glance.

When I called them, the guy had no idea what I wanted. Said they typically do not have that kind of info on hand. He gave me his email and told me to email him what I wanted. That was Monday. Im guessing it got passed around. Its obviously a scan and the paper has my email written on it.
How does it compare to the 820S and the pure one in flow and filtering?
Better than the FL820s in both flow in filtering. IIRC, the FL820S is around 80% at 20u efficiency. Worse than the Pureone, and I know that. I would guess better flow, however.

I'm assuming the flow vs PSID graph for the FL820 is with hot oil ... typically what you'd see on the road (~ 200 deg F, 5w-30).
Here's flow vs. PSID data from Purolator on the PL14006 PureONE, which is a little smaller in size than the FL820.
Note that at 12 GPM, the PSID is slightly over 5 psi for the PureONE ... it to flows very well IMO.
I'm guessing the FL820 is a PureONE variant ... the F probably means "Ford" and the L is an artifact of the Purolator nomenclature - the PureONEs use a "PL" prefix in the filter numbers (that's my theory anyway
)
