I finally got a few filters cut and photographed, first a FL-400S that was run for 3,300 miles on my Jeep. This is the filter that solved my start up rattle and got me started on my current tour experiment of Jeep Liberty filters for my Grand Cherokee. The oil was Castrol HM with MoS2.
The other filter is an FL-910S off of my son's Chrysler Sebring. It was run for 5k with Maxlife 5w30. I figured it was easier to do both these at once, and I don't think we had an FL-910S in our data base here anyway.
The FL-400S and FL-910S share virtually identical specs, the difference being the FL-910S is significantly shorter. If you have room either filter would fit on the same vehicle.
I do not have a filter cutter so you'll just have to deal with the carnage. On to the guts!
Side by side:
Base plates appear identical and are typical Purolator.
Both these filters feature silicone ADBV's, thus the "S" designation. Both were very soft, pliable and intact.
Elements out and side by side:
FL-910S media up close. The 910s had 59 pleats.
The FL-400S media up close, the 400s had 58 pleats.
FL-910S seam side of media, the seam on the 910S was a metal crimp job.
Seam side of the FL-400S, it was simply a glued seam.
Measurement on the length of the media on the FL-910S. The media was notably "wavier" than the media on the FL-400S. The 910S is a small filter, I can't help but wonder if the wavy pleats were due to higher oil pressure flow against the media due to it's small size.
Measurement on the 400s:
Leaf springs were identical as you'd expect.
I gave the metal endcaps on these some good tugging on and they were rock solid and not going to come off without tools and determination. All in all these are typical Motorcrafts quality of construction was very good IMO. Motorcrafts remain some of my favorite filters and they are just about impossible to beat for the buck if an S series fits your vehicle.
