More "halo effect" analysis.
Doubt the Ultra is any more restrictive than say a PureOne. I'd like to see a "Flow vs PSID" bench test to compare to the PL14006 that SuperBusa had Purolator test for flow performance. Link:

And there's nothing wrong with FRAM's bypass valve design. That subject has been hashed over many times. I actually think FRAM's bypass valve design is solid - like the fact it uses a coil spring and a high temperature nylon material valve which would tend to seal better than a metal-on-metal valve design.

Some already explained why ... because the way the Ultra is built with multi-layers and metal wire backed media, they had to use metal end caps and potting material to ensure a good seal at the ends of the pleats.

Did you see that video on You tube where even the Fram Ultra filter fails??? the guy takes it off his car and when he shakes the filter you can hear broken filter inside... I bet its the bypass valve.. I would think b.c oil restriction the bypass valve is used or open when you go long OCI and it finally failed.. I think he said he had 10000 miles on the Fram Ultra.
Can you link up that YouTube video? I'd like to see that one.
Here is the video
http://www.youtube.com/watch?v=NexBveNFZjg
it failed after 4800 miles
Fram Ultra XG2 15,000 Mile Filter failed after 4,800 Miles in a 3.0L Duratech Engine Mobil 1 Oil
I think its b/c the leaf spring..... If fram would just use a Coil Spring they would not have that problem.
