No, they are made by Wix. Purolator is made by Purolator.
Both Wix and Purolator are owned by the same parent company (Mann+Hummel), but the companies (as of now) are still separate and share no manufacturing facilities or processes. There has not been any posts of decreased quality of Wix filters.
Funny thing is you will use a Mann filter that is made by the same company that owns Wix and Purolator, but use their ownership to not buy them.
