The Royal Enfield 143497/B Pipe – Suction is a replacement rubber hose designed for the air-intake system of compatible Royal Enfield UCE 350 motorcycles.
This suction pipe connects the air filter box to the resonator, helping maintain a properly connected air-intake passage. Replacing a cracked, hardened or damaged hose can help restore correct sealing and prevent unfiltered air from entering through gaps in the intake connection.
