AIR FILTER
Air filter from the battery carrier and air filter assembly, later superseded by AC-900.
This is the air filter listed under Triumph part number 82-6431, shown in the catalog under the battery carrier and air filter figures. It sits alongside the battery in that corner of the frame where the intake side of the carburetor draws its air, and its job is to keep grit and road dust out of the carb before it gets pulled into the engine.

The catalog shows this number appearing across entries from 1965 to 1967, and it was later superseded by factory number AC-900 — if your parts book or an older bike shows 82-6431, that's the same part under its earlier designation before the change. The legacy alias F6431 turns up in some records too, referring to this same physical piece.
