GM 6.5L V8 – Outside Air Intake Duct and Air Filter Assembly

Outside air enters the induction system at a duct located between the right front inner and outer fenders (refer to Figure 6-2). It flows into the air filter assembly, which contains a replaceable filter element located inside a two-piece housing made of composite material. The air filter housing mounts to the right inner fender with a bracket and bolts. It has a moisture drain positioned on its bottom side.

The outlet of the air filter connects to the turbocharger inlet with a reinforced flexible duct, using screw-type clamps (see Figure 6-3). The sealing of this duct is very important in protecting the turbocharger compressor wheel from damage by unfiltered particles.
