Baldwin B7444 long length NAPA Platinum 47045 long length. I am not an advocate for either filter. I simply have done some home work and studied what they have in them and how they are made. They are both synthetic medium filters. They are both well made. They both have the two critical valves that our engines need. They both have the flow rate needed and they both have high particulate ratings. There are others that are just as expensive and may do the same thing. But this is what I use.
