Consider the following:

I'm sure that at some point this link has been posted, but in light of
the recent discussion, I believe that it may deserve a repeat. This guy
dissected quite a few filters for this study. The results are
enlightening. There is significant variance with regard to internal
design and manufacture.

#FWIW, mopar filters are quite often the same FRAM filter that are also
#branded
#as Penzoil or Quaker State. When my son worked for the local Dodge
dealer
#he
#used to bring home filters for me. Many were obviously FRAM's others
had an
#oblong hole that I could not ID the manufacturer of. If you are looking
for
#a
#consistently manufacturered filter I would stay away from the mopar
brand.
#
#Currently I am using Motorcraft filters (they have been rebranded
Purolator
#for
#the last couple of years). FL300 on the Dakota (no room for the FL1A),
FL1A
#on
#the Barracuda and FL400 on the PT. Less than $3 at Wal-Mart.
