Very, Very few.
How many companies utilize metal endcaps?
EVERYONE else (Even the Fram Ultra so it must be better right)
I wonder why that is? It isn't to cut cost. It doesn't reduce labor, it's just because it works. End of story. Checkmate. King me. If a filter is designed with endcaps, the entire world (minus Fram) has unanimously agreed that they should be metal.
How about all the filters that have no endcaps at all? There is no engineering reason for metal endocaps.
"Checkmate...king me...end of story..." You are like a little kid. How old are you again?
You should re-read what I wrote more carefully. Filters with no endcaps are obviously a different design that do not rely on them as a vital component to the filter as a whole.

Sure lets do a quick class:
Which is stronger, cardboard or metal?
Which material retains its shape and strength better when wet?
Which will continually perform better when it spends its life submerged in oil?
Class dismissed, the answers are clear! Your welcome zee, free education for you.
What material do you reckon a paper cellulose filter is made of?
No one has ever said it wasn't a good medium for filtration. It just sucks as end cap material. Feel free to google Fram failure and look at all the deformed and darn near disintegrated OCODs out there.
