Hmm interesting.  I can only stand by what I experienced... Just like Stpltn250r has his experience.

Yes, there are quite a few that switched to the BF AEM filter with great results.

When mine was having issues, I was running the 4x8" dual layer Uni w/the 6-2xl needle.  This is a big ass filter.  I wish I had a flow bench, so I could check the flow differences between the foam 4x8, foam 4x6, and the gauze 4x8 and 4x6 filters.

Anyway, hope you figure out your issue and enjoy that beast!
