I know several, including myself, don't like nitrile ADBVs or combo valves. I just cut one of the new SuperTech ST2s open. It doesn't appear to be a bad filter, but I was wondering how many miles someone has ran this filter (or other new ecore) and had the ADBV still functioning. I would like to see this filter with a silicone ADBV. The combo valve doesn't bother me as much as the nitrile.
Just looking at it, I would trust this filter more than a MC FL-820s.
