  Air Duct, Hose Air

• Description:

  This genuine Ford engine air intake hose is the pre-formed molded duct that carries filtered air from the air cleaner outlet into the throttle body on 6.2L gas Super Duty trucks. Ford catalogs it as Hose - Air under base 9B659. It fits 2011 through 2013 Ford F-250 F-350 F-450 and F-550 Super Duty pickups equipped with the 8-cylinder 6.2L naturally aspirated gas engine. The molded rubber and plastic construction is shaped to route around underhood components and seal tightly at both ends so unmetered air cannot bypass the mass air sensor. Over years of heat cycling and engine vibration these ducts crack, split at the bellows, or tear loose at the clamp collars, which a buyer often notices as a rough idle, a whistling or sucking noise under the hood, a check engine light for a lean condition or MAF correlation, and hesitation under throttle. Replacing a hardened or split intake hose restores a sealed path from the filter to the throttle body and correct air metering. This is the correct 6.2L gas variant, distinct from the 6.7L Power Stroke diesel intake hose that shares the same base number, so confirm your engine before ordering. Installation involves loosening the hose clamps at each end, releasing any breather or crankcase vent connections, and seating the new duct fully before retightening. Inspect the clamps and any grommets while the hose is off and replace anything cracked to guarantee a leak-free seal.
