I mentioned it in the other thread, but I’m pretty well convinced the “long” HAMP are exactly the A01 save for the markings. (also allegedly the A01”PE” is the same but does not have the tightening marks - I have not verified that though)
I have cut a number of the A01 and A02 with around 9,000-10,000 miles on them open and posted here, I would have ZERO issues running any of the Honda filters (and that includes the A02) that long, I’m a little more reluctant to run them longer, but Honda does appear to be OK with 20,000. With that in mind a HAMP for around 15,000 is next on deck.
