Found more info on this filter:

Scroll down to the bottom to view the actual comparison pics.
This is the one I have:
TOYOTA 90915-20004
Made in Japan by Denso; also marked 115010-5021
This filter is not available as a replacement item and is apparently intended only for initial filtering on a newly-manufactured engine. Supplied on new vehicles.
Depth-type filter element, 65mm O.D., 31mm I.D., with a height of 72mm. The filter element is not of uniform thickness, but is grooved to increase its outside (entry) surface area. Not similar in construction to other filters in this study.
Eight entry holes in base, thru which a red silicone rubber antidrainback (ADB) valve can be seen. Looking thru the outlet (the center hole), the center rivet and moving portion of the steel-on-steel by-pass valve can be seen at the far end.
Seating gasket is an O-ring with 70mm O.D., 64mm I.D. The O-ring is crimped in place.
The steel housing is very strong, 0.019” thick.
