  Engine Air Intake Hose, Hose Air

• Description:

  This genuine Ford engine air intake hose is the molded air inlet duct that channels filtered air from the air cleaner housing to the throttle body on the 2019-2023 Ford Transit Connect equipped with the 2.0L gasoline four-cylinder engine. Cataloged by Ford as the Intake Hose under part number KV6Z-9B659-B, it is a pre-formed, application-specific component with integrated connection points and any factory ports for crankcase ventilation or resonance control. Because it carries the full metered airflow to the engine, a sound intake hose is essential for a correct air-fuel mixture, smooth idle, and proper throttle response. The rubber and composite material hardens, cracks, tears, or splits at the bends and clamp areas with age, heat cycling, and engine movement, creating unmetered air leaks downstream of the mass air flow sensor. Symptoms a buyer is usually chasing include a rough or unstable idle, hesitation or stumble under acceleration, a hissing or sucking noise from the engine bay, reduced fuel economy, an illuminated check-engine light with lean or airflow-related fault codes, and in severe cases stalling. Replacing a split or collapsed intake hose with the correct molded Ford part restores a sealed, unrestricted air path and factory driveability. Installation is straightforward: loosen the retaining clamps at the air box and throttle body, disconnect any breather fittings, remove the old hose, and fit the new one, ensuring the clamps are seated and tightened so no air can bypass the sensor. Supplied as a genuine Ford OEM component for exact fit and reliable sealing.
