"Fleetguard" Filter Observation

[7TFord]

I just purchased a dozen Fleetguard LF3614 oil filters for our 2008 Toyota Yaris. I have never used a Fleetguard product before and the first thing I noticed is that it has a centre tube like no other filter that I have seen. The openings in the tube are more like slits not holes. These slits look closed off from the outside but may be open only on the side facing the bottom of the filter. It is hard to tell. I was wondering if anyone had torn one of these filters apart and had a pic of the tube and maybe even an explanation of the theory behind this design?

Thanks

I don't know about anyone else, but I'm having a hard time getting a mental picture of what you're describing. Can you post a pic?

Got only one hit here on "Louvers" from 2004 with a search. Links to pics now dead but a reference made to better flow with this design. Are the openings indeed on the side facing the bottom?

Here is a teardown of a different Fleetguard p/n which has holes.

That's interesting. I wonder what the technical reason would be to have the holes in the louvers facing away from the direction that the oil moving through them needs to flow?

Actually the Amsoil, Donaldson and Fleetguard LF3315 filter at your above link feature the "louvered" style of centre tube. They didn't feel the need though to mention this louvering as being significant.

That is a darn good looking filter.

x2....I've used that particular one on my Dodge before. They certainly hold their own.
