Seems like deja vu regarding this topic, but I'll give it a shot again. I suppose cheap is in the eye of the beholder, but just because the metal coil spring bypass is exposed and viewable down the center tube doesn't necessarily make it "cheap" or "too simple". As I said in the other related thread, as long as the design works, ie., does what's it's supposed to, open at the specified psid, then it's just fine in my book.
And also as said in the other thread, if the oem uses that design that means they stand behind it's quality and function. So the exposed spring wouldn't keep me from using this filter as specified if I so chose.
Now if you were talking about a nitrile combo valve being used here instead of the separate adbv and metal coil spring bybass, then I might agree with the more cheaply made characterization, but that would be just my opinion. And that's another discussion not asked here.
