Changed oil in the 2000 Miata after 5000 miles of use. Old oil was MS5K with Bosch filter. Didn't see any problems with the filter. Anti drain valve was very pliable. Overall a well built filter.
Pleats were straight. No tears. There was a gap on each side of the end crimp.
Dome end bypass
Removed pleats for closer inspection. No tears. Did see some small pieces of metal. The pieces were moved by a magnet.
No trash in the dome end.
