Royal Enfield Air Filter Element (Old Model, Metal Gauze Inside) | 110673 | Bullet 350 Genuine OEM

Royal Enfield 110673 is the genuine Air Filter Element (listed as “AIR FILTER (SPARES)”) used on early/legacy Bullet-style airbox setups, identifiable by the rectangular air filter box and the metal gauze on the inside of the element. 

If your bike feels slightly “choked,” mileage has dropped, throttle response is dull, or the existing filter is oily/blocked, replacing the air filter element is one of the highest ROI services you can do. On older Bullets, a fresh OEM-spec element helps the carb/air-fuel system breathe correctly and reduces dust ingestion risk—critical for engine life.

This is a Genuine Royal Enfield part, meaning the fit and sealing are made to factory spec (unlike many aftermarket “old model” filters that don’t seal cleanly and let dust bypass). Fitment safety note: 110673 is not universal across all Bullet/Standard generations. Please match by part number and confirm your airbox type (rectangular box / metal gauze inside) before ordering.

FAQs 

1) Is 110673 an air filter element or the full air filter box?
It is the air filter element (fits inside the rectangular airbox). 

2) How do I confirm this is the right filter for my bike?
Match part number 110673 in your parts manual/microfiche and visually confirm the rectangular air filter box + metal gauze inside element style.

3) Will this fit UCE Classic 350/500, J-Series (Reborn/Meteor/Hunter), 650 Twins, Himalayan?
Not confirmed. Those platforms use different intake/airbox systems—order only if your official parts lookup shows 110673.

4) How often should I replace it?
For older bikes, replace earlier if you ride in dust/traffic. If the element is dark, oily, or restricted, change it—airflow directly affects performance and engine protection.

5) Any size reference to double-check?
A dealer listing provides a helpful cross-check size: ~3 3/8" tall x ~3 1/2" OD.
