I have the infamous UFI oil filter for the GM 1.4 Turbo. Most housings are Hengst. It seems less came with the UFI housing marked UFI. Has the bypass spring on the filter. Thus, there are less options for those of us blessed with a UFI housing. I have no problem finding AC Delco. Parts stores usually have another brand in stock. One option I saw on Amazon is Ecoguard. I haven't heard much about them. I have used their cabin filters before, but this is oil filters we Re talking about. I wanna be a little careful. Thanks!
