I've been running a larger than OEM filter on my 3.0 in the factory location. PL20195 from Advance. It's supposed to be a Ford SHO filter (PH3614) #. I went back to using stock size filters just to make life easier b/c I have 3 toyotas to buy filters for. easier to have a bunch on hand.
FYI: don't ever use Fram; junk. Pure One, Mobil 1, Baldwin, Napa premium (wix) are good choices.
