Genuine Royal Enfield 810058 – AIR FILTER ASSY W/STICK CL GM GREY. This is the genuine right-hand air filter box / air cleaner housing assembly with sticker used on the Classic 350 UCE Gun Grey / Gun Metal Grey BSIV configuration.

Royal Enfield's Gun Grey 2017 exclusive-parts document explicitly lists 810058 as “AIR FILTER BOX ASSY WITH STICKER” for model code 1800286. The document states that the Gun Grey motorcycle is based on the Classic 350 Black BSIV platform and lists 810058 alongside the matching colour-specific tank, mudguards and electrical toolbox.

Restore the factory right-side airbox on your Gun Grey Classic 350 UCE with genuine 810058 – the colour-matched RH air-filter-box assembly with sticker for the BSIV Gun Grey configuration.

Detailed Product Description

The Royal Enfield 810058 Air Filter Box Assembly is a model- and colour-specific intake-side body assembly for the Classic 350 UCE Gun Grey / Gun Metal Grey BSIV motorcycle. It forms the visible right-side air-filter housing / airbox section and carries the correct Gun Grey sticker specification.

The official Gun Grey 2017 Exclusive Parts Details, Version 2 dated 28 Nov 2017 lists 810058 directly as the Air Filter Box Assy with Sticker. The same factory document gives model code 1800286 and identifies the base motorcycle as the Classic 350 Black BSIV.

Current Royal Enfield 2026 spare-parts data still lists the same unsuffixed 810058 under the factory description AIR FILTER ASSY W/STICK CL GM GREY. That supports retaining the exact unsuffixed SKU rather than adding an invented /A or /B suffix.

The side can also be separated from the matching electrical toolbox: Royal Enfield parts references identify the toolbox sticker as LH and the air-filter-box sticker as RH. Therefore 810058 should be listed as the RH / right-side air filter box, while 810057 is the matching LH electrical toolbox for the Gun Grey body family.

Installation Notes

• Confirm part number 810058, Gun Grey finish and RH air-filter-box requirement before installation.
• Compare all mounting points and intake connections with the removed assembly.
• Inspect the filter element before refitting; replace separately if dirty or damaged.
