Ford FL-820S Filter Alternatives

The one thing that has me curious, is on the FL-820s and purolator premium plus, there are major gaps in the pleats as if there are not spaced evenly at the factory. On my 2 filters I cut open, it is evident the oil flows toward the path of least resistance. The areas where the pleats have big gaps also have more debris in them, and showed signs of collapse thus evidence that the oil flow was primarly there.

Is this a bad thing? And is there a reason why the factory cannot space them evenly such as on the Wix filter?
 
I have added two more filters to my "Other Filters" page - an Purolator PL14477 and NAPA ProSelect 21356. The PL14477 is off of a 4 cylinder Toyota RAV4. The 21356 is off of a 2004 Honda Accord 4 cylinder (and also fits my 2006 Nissan Frontier V-6)

Ford Racing oil filter vs. Fleetguard LF3315? Which one is better for high rpm protection is my question?

What do you mean by high RPM, racing ? and what is OCI ? Also is application Ford in warranty ?

If I was tracking a 2005 Mustang and changing the oil after runs Ford Racing looks attractive (as does a K&N).

If I'm trailer towing in dusty climate with a big block engine (especially diesel) the Fleetguard may be my preference.
 
Ed, you did an incredible job in your study... my hat's off to you!

Bump.

Here's what Ford says about the Ford Racing oil filters in the Ford Racing Performance Parts 2008 catalogue, page 116:

So it appears that you could run these on the street for at least as long as the standard Motorcraft. The specs seem to answer many of the concerns some expressed earlier in this thread. Note the claim that the Racing filters have "50% more filtering capacity"—but no mention of difference in flow compared to standard. In addition, all these have silicone ADBVs, hence no need to add the "S" as some of the standard Motorcraft filters do to indicate it. Therefore, this could be an option for those who want (example) an FL1A but with the better ADBV material. Too bad the cost is ridiculous. K&N is cheap by comparison, and the Amsoil EaO series is pretty competitive here. To address the original thread topic, it's not clear whether the Racing 820 filter would really give much advantage compared with the FL820S.

Oddly enough, the catalogue gives what appears to be the part number for individual filters, but then says in a footnote to the chart: "Check Ford Racing Distributors for single filter part numbers." Eh? No dimensions or other specs by filter number are given.
 
sorry to dig this back up but i was wondering about the higher capacity filters. the bypass spring on the 820s has a setting of 12.5 to 18.5psi(according to the chart on here http://home.mindspring.com/~cewhite3nc/id9.html). quite a wide range. if it really is that wide a range i don't see a problem using a bigger wix with an 18 or so psi spring? and in that case isn't the bypass spring designed around the filter and not the engine?
 
the reason i'm wondering is i might be running a high volume oil pump on my 4.6. i would buy the ford racing filter but the cost has me considering a larger wix that i could get for less than half the cost.
 
wheres the cheapest ford racing filter i can buy? everywhere i've seen they go for $13 plus shipping. it seems like ford racing isn't letting people whole sale them and sell any cheaper than the list price?
 
its gone. ed took it down due to it being kind of old. it was great info. but i saved the whole sha-bang when i found out it was being taken down. from site before taken down - "All good things (and bad ones too) must come to an end. The information on this site is stale. I don't have the time or energy to properly update the information, so I've decided to delete the site at the end of the month. Feel free to copy any of the infomration you'd like to retain, but be sure to understand it is getting old and may no longer be representative of current products."

i'm a poster on svtperformance and it seems there is going to be an oil filter study going on there sometime in the near future for fl-820s and equivalent filters. last time i heard they had over 30 filters, you name it, he's got it. company representatives were even sending in filters(for cost of shipping or even free i presume)and still are!

after he's done with that he also wants to do a flow/filtering test.
