This air hose routes pressurized intake air from the turbocharger outlet to the engine’s charge-air cooler. It sits in the induction system between the compressor discharge and the cooler inlet, maintaining a sealed path for the boosted air charge. A cracked or collapsed hose causes boost-pressure loss, which reduces engine power and increases exhaust temperature. This original AGCO component is molded to the same internal diameter and bend radius as the factory hose, so it aligns with the clamp positions on the cooler and turbo without requiring adapter sleeves. When replacing, inspect the O-ring seals on both connection ends and replace them if hardened or cracked.
