Opinion on Bosch filters

They're apparently exactly the same as STP filters, or were, before STP switched to the E-Core design.
I'm not sure if Bosch is going to switch to the E-core design as well?
I've used one for a rather short OCI...don't really know how it did because I just took it off and tossed it away lol.

Made by, doesn't mean identical to. Also, I think there is a higher grade of Bosch not made by Champion. Cutting open a filter tells a lot. However, it tells you nothing about the quality of the media unless it has failed. Filters appearing similar, may vary in quality.
New designs, such as the Ecore, need to prove themselves. There has been a lot of negative speculation here about them, but the positive reports from use, vastly out number the negative one.

The Bosch sold at AZ and shucks/kragen/checkers is a good filter, however I'd buy a WIX or Pureone if the prices are similar.
I just found a Bosch 3500, and I'm gonna rip it open soon, and I'll post what I find.
I used a Bosch from a Rebate about a year ago, and an STP the next oil change which was $2 off and cut them both apart. They seemed identical except for the media. The Bosch media seemed thicker, but nothing special.
They have a silicone ADBV. (good) The newer Bosch filters have the clicker bypass valve. (Blech)
Aside from being dome end, just what is the problem with the clicker? I hadn't paid that much attention to them until ST switched my 3950 to them. I am looking for something more than ''don't like the looks'', or ''don't understand how they work''.
I have cut up several off my truck, and haven't seen any problems.
I just finished cutting open the Bosch 3500 I just bought... yes, it IS a clicker (the first one I've seen in person). I also see no problem with the clicker design - it's rather elegant in its simplicity.
It has 282sq.in. of element area, which places it mid-pack among the FL-1A equivalents I've cut open so far. The Fram HP1 is at the top with 385sq.in. and the Fram PH8A is at the bottom with 180sq.in.
Of course, what I don't know from all of this filter-opening is the quality of the media itself.
This Bosch looks like a well-made filter, one of Champ's better efforts, but it seems unremarkable compared with its peers.
Just my $.02.

It seems to me that the "new" filter materials are 3 dimensional in filtering. Not sure how area of a filter has any real meaning anymore.
Seems to me that a "furry" 3D filter could quite possibly require less surface area.
Any comments?

I think spin on filters have always used 3 dimensional media, trapping grit in the pores. Thicker should be better, and it could have more holes per square inch. Unfortunately, I see very little here about quality of media, other than synthetics are better.
The much dissed thimble filters could make up in quality what they lose in quanity.
