Fram lineup vs. Supertech vs. Mann cartridges for VW/Audi EA888.3

Is there more air gap between the tower in the housing and the center tube of the Endurance compared to other cartridge filters? The more air gap in that location, the more potential for the filter to cave in some due to the dP across the media.

I'm not sure TBH, would need to pull it again and check. I still have an extra Endurance so can do that next time I mess around with it. Thanks.
This is likely the case I suspect, just not what I expected after seeing many Mann filters come out looking exactly like they go in.
See if there is less air gap on he Mann. Structural strength of the cartridge also a factor. but less air gap will prevent less cave in due to dP across the media. Some cartridge filters come with their own nylon Ecore cage, mainly for vehicles that may not have a stand tube in the housing like yours.
Same design as the Mann/Hengst...different than the Fram style that have the felt ring on either end.
This is what I'm using @TiGeo

I think I'm cheaper with FCP, if I divy up the return shipping portion to the filter, it's probably a buck.
I bought a Fram Endurance for my GLI at Walmart. Appears to be made excellent.
I can tell you one thing, air gap or not (all of mine do not have a gap), the endcaps on the Mann are STRONG. Never had one crush, collapse, or break apart in all the years I've been using them. I'd use them for jackstands if they were taller 
, they're that strong. Just got another dozen of the green and yellow beauties from FreeCP Euro.

They really are more rigid than the others I had in my comparo Those end caps are thick vs. the thinner Fram ones that use the "felt" rings on top.I can tell you one thing, air gap or not (all of mine do not have a gap), the endcaps on the Mann are STRONG.

Ok. End caps on Endurance are hard plastic. The filter itself is somewhat softer feeling to squeezing than the more rigid feeling Mann. I can sense squeezing it why it ended up like that.I can tell you one thing, air gap or not (all of mine do not have a gap), the endcaps on the Mann are STRONG.

Ah, evolution
.What determines if the media on a cartridge filter (without its own Ecore cage like yours) is going to "cave in" from oil flow dP is the air gap between the standoff pipe and the center hole of the filter, and of course how ridged the media in the direction of oil flow. Solid end caps aren't going to help really prevent media "cave in" from flow dP. Your post 36 describes that.
The blue one immediately made me think of my LS2 oil fill cap; the OEM ones (AC Delco FC244 / GM# 12643759) are blue from the factory, but it's just a black rubber o-ring with a blue coating of some sort that starts coming off the first time you remove the cap for the first oil change.
Teflon coated ... or perhaps trying to fake that it's "silicone" ?
