These two parts both touch the oil system and they do not replace each other. One is the angled washer on the oil-filter rotor. The other is a magnetic drain plug. Match the part you removed.

Buy the 16mm angled washer when the rotor washer is worn. Buy the magnetic plug when you are replacing the drain plug that uses 90013-312-000. There is no oil filter element in this pair.
The rotor washer is a 16mm angled washer, Honda 90481-292-000, and the description names the 1975-76 CB500T. The magnetic plug replaces 90013-312-000. If you are only refreshing the rotor, the plug does not belong in that order. If you are only changing the drain plug, you do not need the washer.
There is no filter cartridge here
The category name mentions oil filters, but the two parts you can order are the rotor washer and the magnetic drain plug. Do not expect a spin-on filter element in either box.
Oil-part questions
Is the 16mm washer a drain-plug washer?
No. It is the angled washer for the oil-filter rotor, replacing 90481-292-000. The drain plug is the separate magnetic plug, 90013-312-000.
Does the rotor washer name this twin?
Yes. The fitment includes the 1975-76 CB500T, plus CB450, CL450, and several CB350 and CB360 models. The size printed is 16mm.
Should I replace both at once?
Only if both pieces on your engine are worn. They do different jobs, so a tired plug is not a reason to buy the rotor washer.
