Genuine Royal Enfield Meteor 350, Classic 350 Reborn, Bullet 350 & Goan Classic 350 Air Filter Box Assembly – RLY00268

Exact Royal Enfield air-intake replacement identified by part number RLY00268. This air filter box assembly is catalogued for the Royal Enfield Meteor 350, Classic 350 Reborn, new Bullet 350 and Goan Classic 350. It houses the air filter element and forms the controlled intake enclosure between the fresh-air inlet and the engine intake system.

Use the part number—not appearance alone—to order. Current catalogues may show the later marking RLY00268/B (also cross-referenced as 309135). Because suffixes can identify a revision, production update or market-specific supply, match the label on the old component or obtain VIN-based confirmation before substituting RLY00268 and RLY00268/B.

• Engine air-induction housing for compatible 350 cc J-series motorcycles
• One replacement air filter box assembly as supplied
• Model-specific component—not a universal air filter enclosure

What This Product Is Not

• Not a performance air filter, Stage 2 cover or tuning kit
• Not a complete induction system with every hose, clip, gasket and fastener

Product Highlights

• Exact-MPN identification: created around Royal Enfield part number RLY00268 to reduce visual-match errors.
• Four confirmed motorcycle families: Meteor 350, Classic 350 Reborn, new Bullet 350 and Goan Classic 350.
• Intake-system function: encloses the filter element and supports a sealed, controlled route for intake air.
• Factory-layout replacement: intended for the original mounting arrangement, hoses, cover and filter used by the compatible motorcycle.
• Revision awareness: RLY00268/B is shown in later/current catalogues, helping buyers recognise a possible updated label without assuming interchangeability.
• Wrong-model protection: Hunter 350 is specifically excluded because it uses a different airbox assembly number.

Check Before Ordering

Not Confirmed / Not Compatible

Sharing a 350 cc engine family or the same air filter element does not prove that the complete airbox housing is interchangeable. Mountings, covers, hoses and emissions plumbing can differ.

Part-Number and Similar-Part Comparison

Function and Use

The air filter box supports the motorcycle’s intake-filtration system by holding the filter element in a defined enclosure and directing filtered air toward the engine. Correct sealing is important: an improperly fitted cover, damaged gasket, loose hose or cracked housing can allow unfiltered air or unwanted air leakage. This component restores the original-style airbox arrangement; it is not advertised as a power-increasing modification.

Box Contents

• 1 × Royal Enfield RLY00268 Air Filter Box Assembly

Important: the filter element, inlet cover, rubber gasket, breather hose, drain pipe, clips, screws, bolts and other induction parts are shown as separate catalogue positions. They are not guaranteed to be included unless they are physically present in the sealed package or specifically stated on the invoice. Reuse existing serviceable hardware only where permitted by the workshop procedure.

Installation Guidance

1. Switch off the motorcycle, allow the engine to cool and support the bike securely.
2. Confirm RLY00268 on the ordered part and compare the complete housing with the removed airbox.
3. Inspect the air filter element, inlet cover, gasket, intake connection, breather hose, drain pipe, clips and fasteners; renew damaged or hardened parts.
4. Keep dirt, loose hardware and cleaning debris away from the open intake tract.
5. Transfer only the components specified by the correct Royal Enfield workshop procedure.
6. Seat every gasket, cover, hose and clamp correctly so the intake system is sealed and strain-free.
7. Tighten fasteners to the current model-specific torque specification and verify clearance from wiring, bodywork and moving parts.
8. Before starting the engine, confirm that a serviceable filter element is installed and the airbox is fully closed.
9. After installation, check for abnormal intake noise, warning lamps, loose connections or air leaks.

Professional installation is recommended. Never operate the engine with an open intake or without the correct filter element.

Do not assume it is included. The related inlet cover is separately catalogued as RLY00008.

12. Are the gasket, hoses, clips and bolts included?

20. How do I avoid ordering the wrong part?

Match the exact bike generation, VIN, old-part MPN and suffix; confirm that you require the complete airbox rather than the filter, cover or Hunter 350 assembly.
