UPDATE:  This page is the Mopar section from the original page.
 

Description

This section features a special look at other oil filter alternatives for the 2.2L and 2.5L engines, listed by Mopar part number.  Keep in mind that these filters are designed for different engines and have different dimensions.  So, it's not fair to compare them with the other filters on this page.  The fact of the matter is, these filters are made by the other manufacturers on this page.  My mission was to uncover who is who.  What I found is that Mopar uses several different manufacturers.

Conversion Table

If you cannot use the Ford 5.0L filter because of clearance problems, try using one of the alternatives listed here.  I have included the outside dimensions so you can see if it will work for you, and they are listed below in order of increasing size.  If you find a filter that will fit, you can use that type of vehicle and engine to look up that filter design for other manufacturers (or the same manufacturer, but a different brand).

The chart below shows the part numbers shown here, as well as the engine it belongs to.  You can use that information to look up these filters for other brands.  I have supplied only the number for those with multiple varieties.  Just add the prefix for the model you want.  For example, the Purolator 10241 number is the L10241 for the Premium Plus, PL10241 for the Pure One, etc.

This is the stock 2.2L and 2.5L oil filter through about 1990, from the dealership.  I have this information here so that you can see why you should not be using this stock sized filter anymore.  This one is made by Champion Industries.  With a tiny surface area of only 124 sqin it has less than 35% of the surface area of the STP S-01 version (360 sqin), which is also a Champion.  Once that small filtration area has been plugged, the oil is directed through the bypass valve and the filter is useless.

This filter is also a stock 2.2L and 2.5L, but for 1991 and later engines, though it fits them all.  It is from the dealership and is made by Purolator.  It is an upgrade from the stock filter, with about 48% more filtration area.  If you have clearance problems with the Ford 5.0L filter because of your alternator, you can try this model.  Use the Overall Filter Length and Diameter to see if it will fit.

I purchased this filter from two places, to prove a point.  The point is that Mopar filters are like a box of chocolates; you never know what you are going to get.  In fact, this seems to be true of many OEM and some clone-brand filters.  I purchased one filter from my local dealer and the other from a nearby store that stocks some Mopar parts (Murray's Auto Parts).  Though the Mopar part numbers are the same, the filters are completely different.  You can identify the manufacturer of a particular filter by looking at the backplate.  See the AC Delco, Champion, Fram, Purolator, and Wix sections for the details on what to look for.

The filter from Murray's Auto Parts has probably been sitting on the shelf for a little while, so I imagine that it is an older version, but it was not dated.  This filter is made by Champion Laboratories.  It features the one-piece filter cartridge and some rust on the back plate.

The filter from my local Dodge dealership was dated 02/98.  This filter is a Purolator.  While the surface area of the filter element is about the same as the Champion version, the Purolator element paper media seems stronger than the Champion Labs paper media.  However there is the issue with the assembly string on this version.  It's a catch 22.

This filter was interesting, but unfortunately only in bad ways.  I also found this filter at Murray's Auto Parts, but left it there when I looked at the backplate.  I decided to get one from the dealership instead, but it was exactly the same.  Cutting it open confirmed it:  this filter is a Fram Extra Guard (the radioactive orange one).  It's definitely the cheapest Fram design with the infamous anti-drainback valve sealing against the cardboard cartridge end caps, and the plastic bypass valve.  It's always easy to identify a Fram Extra Guard by the cheap looking, thin backplate with many small holes for the oil inlet.  How Chrysler can call this cheap filter a "Severe Duty" filter is beyond me, but it is stamped right on the can.  Even Fram makes better filters than this (Tough Guard), but they probably cost too close to the Mopar $6.50 oil filter price for a decent price mark-up.  Fram does not list a part number for this filter in the Tough Guard version.

If you really must have this filter, consider looking to another brand, such as Purolator or Wix.  Just look up a Dodge Viper or Ram Truck with a 8.0L V10, or use the Mopar Conversion Table above.  The problem is that the Purolator is suspiciously like the Fram, however I know it is not a Fram because of the way it was constructed (assembly string, etc).  Like the Frams, it has cardboard end caps and a few of the pleats were not glued down.  My advise is to avoid all of these filters and go with the Ford 5.0L filters.

Since this filter is popular is Mopar circles, I bought each of these and measured them as well.  I was unable to find the AC Delco version anywhere.  As you can see, this Fram does have more surface area than the PH8A version, but it is still less than an AC Delco, Purolator, or Wix Ford 5.0L filter.  So if you think you are getting a bigger filter with one of these, think again.

Conclusions

It should be clear that Mopar filters are really nothing special.  Unless you are trying to have a perfect restoration and need that Mopar logo, there is no reason why you should be buying Mopar oil filters.  Most of them seem to currently be Purolators or Champions, but that could change at any time.

See the AC Delco, Champion, Fram, Purolator, and Wix sections for information on how to identify these manufacturers by looking at the backplate.  The tell-tale signs are always there.
