Element
Gauze air filter element for the air cleaner box on OIF-era Triumph twins, round-hole type.
This is the air filter element that sits inside the air cleaner box on the OIF-era Triumph twins, catalog PN 60-3618 (also shown as 60-3618* and D3618 in older listings). The figure titles place it under the air cleaner and side panel/sidecover assembly, so it's the gauze element that lives behind the side panel, filtering intake air before it reaches the carburetors.

The catalog record for this element runs from 1971 into the mid-70s, consistent with the oil-in-frame chassis update. It's a wear item — dirt and oil vapor load it up over time, and a clogged element chokes off airflow and can affect running, so it's worth pulling the side panel now and then to have a look at it.
If your parts book lists this under the D3618 or 60-3618* form, it's the same element — just an older or alternate catalog number for the identical part.
