I don't subscribe to the theory that if it is made in Germany and, pardon the redundancy, expensive, it is good. However, Purolator has the dome end bypass others and I dislike. Other than that, I have seen Purolator falling in the middle along with the Champ brands and Hastings, all better than Fram, but inferior to the OEM filters.
If under the new pricing I will be paying more for Bosch, Mann, Hummel ''quality'', for my filter elements, I may move to ST. I hate to pay more if all they change is the box.
