Thread size is the same, gasket is the same. According to my Donaldson Filter catalog, neither have bypass valves nor anti-drain valves. Not sure about the micron rating since they only list micron ratings for their fuel filters. Although, I don't believe micron ratings vary much unless you get into synthetic media filters. It appears, from what I can see, that the powerstroke filter is just a longer version of the nonpowerstroke filter. Hopefully others will also comment.
