The Magnefine just came in the mail, and appears to be well made. It has a flow arrow and states that it employs a check valve, warning to ensure proper installation.
Question: How effective is the check valve? I blew through both ends and noted no resistance in either direction. It may be obvious when I get to it, but in which orientation shouldbth filter be installed, if installed in the OEM location?
The Civic is due for an oil and atf change soon, so maybe I'll take care of both this weekend. If I do I'll also swap out the atf filter and cut open the old OEM one.
