Bought these for my Honda Odyssey with some speed bucks I had at the Advance Auto when I got them noticed one was made in China. The other one was made in Vietnam so I just cut them open to see what the differences were. The one with the darker media and orange gasket is the one made in Vietnam, the black gasket, and the lighter media is the China made one. They both had coil Springs in the bottom for the drain back valve. The Vietnam one had some excess glue around the media the China one did not but very few differences other than the way they look.
