Hi Greg, I see you edited your post. I remember reading about paper element filters vs. the MANN brand fleece filters so I just researched that subject again (did a google search for paper vs fleece). I can't tell from the photos in the link you posted but generally the "aftermarket" look-a-like filters have a paper filter element. Several members have experienced a failure with those paper element filters. The consistent recommendation here in the forum archives has been to stick with the known MANN brand fleece filter . . . specifically the HU718/5X . . .

Getting excited about CAA#6 in June!
