So Wix and Purolator are no longer being operated like separate entities, because it sounds like the new filter was made by Purolator, and the tapping plate had that famous Burrolator quality..I got bored and cut the Wix filter open that I took off the other day. I compared it to the same number, same country of origin Wix that I bought the other day. Base plate looks different, crimps are different, ADBV is a different color. The old filter has holes in the metal core and the new one has louvers. Definitely some changes in the materials used.
