Exactly, the dirt. they allow more dirt to pass-there is no perfromance advantage that is measurable.
OEM, Fram, Wix, Motorcraft, sct... catch more dirt & will flow more air than the engine can breath.
Motorcraft use Purolator Premium media. If you want to filter more, then go with Pure One or Bosch Premium.
Ford specify the bypass at the top of the filter not the bottom and this is only found on Motorcraft. This may mean that the Motorcraft has less media overall as more of the can is taken up with the bypass mechanism. I have both the Motorcraft and Bosch and they are identical apart from that feature and the media.

The kn air filters are bad and allow more dirt. Their oil filters are nice filters. That being said at half the price the motorcraft would have my mind made for me.
These are the PS (black) filters that the OP is referring to, not the HP(white with the nut) series.
Not a lot of info here about them, IRRC they appeared to be a Champ Classic design. Don't remember if anyone got efficiency info or not. There are some posts and pics of a dissected filter here.

So you call the base the "top"?
This is what you said:
"Ford specify the bypass at the top of the filter not the bottom and this is only found on Motorcraft."
For this statement to be true, the "top" of the filter must be the base end. See how confusing that is?Originally Posted By: rjacket
I think you are choosing to be confused by it for a reason only known to yourself.
Do all filters have domes on them?
).
Any end could be the "top" or "bottom" depending on one's perspective. Just like any side of a car could be the left or right side depending on the person's perspective ... but technically, the driver's side is always the left side, unless you have a car with the steering wheel on the right side. 
Here is something else for you genius.
Here is a filter manufacturer refering to the top and bottom:

Here is a forum discussion about the location of the bypass also talking about top and bottom:
http://www.shoclub.com/news.php?extend.3
And lastly, here is WIX refering to upper and lower end caps
http://www.wixfilters.com/productinformation/gff_oilfilters.html
The last time I checked the English language, upper and lower were synonmous with top and bottom.
Lots of people here also talk about upper and lower endcaps when refering to the internals of a filter so I am sure they are not having as much trouble as you understanding this.
Why don't you go and troll those discussions and ask them to explain what they mean by upper and lower endcaps?

... don't tell me, you have a car with the steering wheel in the center. Originally Posted By: rjacket

Don't worry ... I understand it all just fine.So if the filter was mounted upside down from the figures shwow, would it be a "Bottom By-pass" setup?

You don't get it!
We were talking about top and bottom bypass in the context of Motorcraft made by Purolator vs Purolator made by Purolator. Right? Understood this point so far?
As I've shown in two links, it is already understood by *most* people what is the difference between a top and bottom bypass. Right? Understood this point?
So in the context of the bypass, in the context of Motorcraft / Purolator, it is ok to use the terms top and bottom because a top bypass and bottom bypass are already understood terms.
Now if you want to call it a dome bypass or a base bypass, that's up to you. I certainly wouldn't spend my time trolling you on that, because I can figure out what you mean.
So perhaps you can stretch your tiny mind a little and understand that because people *already* refer to the bypass as a top or bottom one (you can find the same elsewhere on these forums), it was ok for me to talk about a bypass being at the top or bottom of the filter.
Comprende?
Of course, I do accept that there will always be people like you whose sole mission in life is to take people's discussions out of context for no reason.
For that reason, you may have the last word on this as I'm removing myself from this thread as I want to stop doing this to you:

... dude, you're pretty worked up, why? Hey, you can call it whatever you want, but it being in the context of a Motorcraft filter really has no bearing on the discussion. Many other brands of filters have base end bypass valves.
Either a filter has a base end bypass or a dome end bypass valve. I see in those (Ford) threads you linked that it typically shows the filter mounted with the base up, and therefore when the bypass valve is in the base it has become the "top end bypass". OK ... whatever floats the Ford guys' boat.
I guess if the filter was horizontal it could have been either a left hand bypass or right hand bypass valve depending if you were looking at the front or rear of the car. 
Bottom line is that most people refer to location of the bypass valve in an oil filter as either base end (or threaded end) and dome end ... expect for the "eccentric". - Status
