Ford FL-820S Filter Alternatives

Ed, I would likewise add my thanks to your efforts.
Wow, I am suprised to see a Wix for a Ford with the wrong end bypass valve. The Wix replacement for FL1A and for FL299 both have the correct Ford-preferred bypass in the threaded end of the filter. I am also suprised that the Purolator seems to have better media than the Wix. Well, maybe I will go back to FL1A filters. They certainly cost less than Wix. But the FL299 is too expensive, but since Purolator rated so highly, I can go back to the Purolator version of the FL299, which is the only Purolator I have ever seen that has the Ford-preferred threaded end bypass valve. Thanks for the filter study.
I have added a Ford Racing CM-6731-FL820 Filter comapriosn page. See http://home.earthlink.net/~cewhite3nc/id11.html . This is a very interesting filter. Too bad it is also very expensive.

i have a whole case of these i got several months ago...cost me 140 bucks at ford dealer i got at cost
this filter filters 95% @ 20u and the bpv is 17-22....i called for these specs..it flows 2.5psid @ 3gpm....5psid @ 13 gpm
Thanks for the specs. I wonder about the flow rate specifications. Is there a standard pressure drop for this measurement? Wix lists a maximum flow rate for thier filters (11 - 13 gpm) but don't list a pressure. I am guessing that is the flow rate at the relief valve setting, but don't know.

How many filters in a case?

I just added pictures of a Kubota 70000-74035 Oil FIlter to my "Other Filters" page. See http://home.earthlink.net/~cewhite3nc/id10.html . This Kubota filter is not an FL-820S equivalent. It is used on many Kubota tractor engines. This particualr filter is from a Kubota M4700DT tractor.

bpv= 12psi
filters=50% @ 12u, 95% @ 25u
there are 12 filters in a case....ed? would you take apart the newer fl820s with the flow tube has alot bigger holes for flow...look inside the filter of the newer fl820s and you will see instead of the many small holes the new one has many large holes...thank you for your hard work!!..i love my fords!!
I have not seen one of the newer FL-820S FIlters yet. I'll keep my eyes open for one.

they are all over here expecially at wall mart.
I have added a new filter to my comparison - a Donaldson P550965. This is essentially a lower cost version of the Amsoil EaO11 Filter. It has conventional media, and a Nitrile Anti-Drain Back Valve, but otherwise it is the same as the Amsoil filter. The direct page for the Donaldson Filter is http://home.earthlink.net/~cewhite3nc/id14.html . The start page for my FL-820 Alternative Filter Comaprison is athttp://home.mindspring.com/~ed_white/id7.html .

It's a difficult comparison without the data for the media. I would tend to think that the racing filter would be not suitable for long term non-racing use. The media is probably substantial to endure the alleged high flow/high transition conditions that one encounters in racing.
Outstanding documentation and detail.
