I just love good discussion!
I forgot one important fact, a lot of you guys are driving SVT Fords. Well it could be that Motorcraft is not the "best" filter for the SVT, but get this, everything is a compromise. There is no good filtration without damaging the flow rate! So we all make compromises, want super filtration? Fine but do not expect a super flow rate of that filter and vice-versa. I believe that for non SVT Duratec' the Motorcraft offers best realtion between advantages and disadvantages (per Oli study mentioned here)in the oili filter construction. And combined with good oil and timely changes it should do fine. Other than that it's every man's game I guess.
