I got a whole case of these oil filters for a really good price. They are for Ford 4.6. They are a white can with Royal in blue letters, the box is light blue with Royal on it. Distributed by E&Y and thats all, no country of orgin, no maker, thats it. Just installation instructions and change evry 5000km They are Part #V4651. I thought with that part number they would be rebadged Purolators. I thought surely I would reconize the end as either a Fram, Champ or Purolator. There are only so many makers of oil filters. They seem to be well built, I havent cut one apart YET, but they are not ecores and look pretty stout inside. Ill have to try to post a picture of one, has anyone ever heard of them?
