I was asked to do an update...maybe a seperate thread will do it more justice.
Pictures are worth a thousand words.
The NAPA's are NAPA/WIX.
Looks like M-1 EP...Amsoil and Baldwin's have the most number of pleats. More pleats equals better filtration and flow usually. Wix/NAPA and K&N are not quite up there.
Amsoil has the best media along with the M-1 EP. Look at the Beefy relief valve on the Amsoil.
I think Amsoil EAO is the overall winner followed by M-1 EP and then Baldwin....K&N and Wix. All are of course good!
Baldwin has a black anti-drain valve that seems to be less reinforced. (make that cheap).
As always just my usual .02.
Compare these pictured to next page.

Hope these are helpful. Lots of great choices. An oil filter is as important as the oil you choose. So choose wisely!!
Notice the paper ends on these filters...The HP-1 Racing has crushed media...the other filter has a plastic tube in it and very few pleats...look at the quality of the black rubber anti-drain valves....compare to the previous pictures...which do you like better?
What's up with the strainer on the racing filter?
Check out the rubber anti-drain valves...vs. the Amsoil...

hydro,
A physical inspection is one method of comparison, but is any info available about the actual ability of each filter to remove engine wear particles and other contaminants from the oil?

Not really an apples to apples comparison. The 1714 NAPA (51714 Wix) application is for Fiat-Allis and Kobota and the Fram PH977A is for the older Ford truck engines. Not exactly a high performance, short oil change interval application. I have no complaints running Wix 51060R's.

A filter is considered nominally efficient at a certain micron level if it can remove 50 percent of particles that size. In other words, a filter that will consistently remove 50% of particles 20 microns or larger is nominally efficient at 20 microns. Engine wear begins with 10+ micron particles.
A filter is considered to achieve absolute filtration efficiency at a certain micron level if it can remove 98.7% of particles that size. So, if a filter can remove 98.7% of particles 20 microns or larger, it achieves absolute efficiency at that micron level.
Most off-the-shelf filters are based upon a cellulose fiber filtration media. Most of these filters are, at best, nominally efficient at 15 to 20 microns. They won't generally achieve absolute efficiency until particle sizes reach 30 microns or higher.
High efficiency oil filters have filtration media made of a combination of at least two of the following: glass, synthetic fibers and cellulose fibers. Those that use all three are generally the best in terms of filtration. Those that use only two will fall somewhere in between. The best of these high efficiency filters will achieve absolute efficiency down to about 10 microns and will be nominally efficient down to 5 microns or so.
This Wix Racing Filter is nomimally efficient at 61 microns...only for RACING where max flow (and comprimised filtration) is needed. It's a good racing filter...not for everyday use per the manufacturer...

Amsoil EaO:
50.0% @ 7 micron (nominal)
98.7% @ 15 microns
99.8% @ 20 microns
Instead of trapping all of the oil contaminants on the surface of a paper (cellulose) type filtration media, high efficiency oil filters have a depth type media which will trap contaminants throughout the entire filtration media. This, combined with the different type of materials used for the filtration media allows high efficiency oil filters to remove more and smaller particles without restricting oil flow - just as high efficiency foam air filters remove more and smaller particles without restricting air flow.

...hope the last couple posts helped you...need info on a specific filter besides the Amsoil/Wix Racing/M-1 ?
