Genuine Royal Enfield Bullet 350 UCE (Kick Start) Air Filter Box Assembly with Sticker – Black – 801624

Royal Enfield 801624 is the Air Filter Box (Airbox) Assembly with Sticker – Black, listed as a genuine Royal Enfield spare.  It is specifically mapped by dealers to Bullet 350 UCE (Kick Start / KS), making it the correct OE-style replacement when your existing airbox is cracked, mounting tabs have broken, the lid seal is leaking, or the intake tract has been altered by local repairs/tape joints. 

A damaged or poorly sealed air filter box can cause unfiltered dust ingress, inconsistent idling, reduced pickup, and premature engine wear—especially on daily-use Bullets in Indian dust conditions. Choosing the OEM airbox helps restore correct fitment, clamp points, and factory-style sealing compared to many aftermarket “airbox shells” that often have misaligned holes, weak plastic, or inconsistent sticker/finish quality. 

This part is also shown as a replacement-linked number on microfiche-style listings (e.g., 866132 → 801624), which supports correct part identification for ordering.
