Air travels from the turbocharger compressor housing to the engine intake manifold through the air inlet duct. A hose with two screw-type clamps forms the joint between the compressor housing and the air inlet duct.
The air inlet duct mounts on the intake manifold, using six bolts and a gasket (see Figure 6-18). A sound insulator covers the air inlet duct and mounts to the intake manifold with four bolts using grommets.
