Is this filter using the combo bypass/ADBV valve?
Zee, I'm not sure I understand the question, so I'll answer it this way: The new Napa ProSelect has the combination adbv/bypass, but the old Napa Silver didn't. In the pics above, the orange dot is the top of a spring-loaded bypass. I'm not excited about the ProSelect, I'd rather have a Napa Silver, but, alas, it is no more.
