Vespa GT/GTS OEM Oil Breather Hose

Maintain your engine's internal pressure balance and prevent messy oil leaks with this Genuine Piaggio OEM Oil Breather Hose (MPN: 844094). This factory-original molded rubber crankcase ventilation hose channels oil vapors and crankcase gases safely out of the engine block and back into the airbox system.

Positioned near the hottest areas of the motor, rubber breather hoses are highly susceptible to drying out, cracking, and hardening over time due to constant exposure to extreme heat and oil mist. A cracked breather hose leads to unmetered vacuum leaks, rough idling, and an unsightly film of oil blowing across your rear suspension and transmission casing. To keep your engine bay clean and running smoothly, it is highly recommended to inspect this hose during routine service intervals and replace it immediately at the first sign of dry-rot or softening.
