Air Intake System Description

2006 Isuzu Ascender S, 5.3 M, 4WDSECTION Air Intake System Description
WARNING: This page is about a different car, the 2007 Isuzu Ascender, 2007 GMC Envoy, 2007 Chevrolet TrailBlazer, and 2007 Buick Rainier. However, it is still accessible from the selected car via links, so may be relevant.

The air induction system provides contaminant filtration and is equipped with 2 resonators to filter unwanted induction noise. As the throttle plate is opened, air is drawn into the air filter housing. The air is pulled through the air filter element which provides maximum air filtration without restricting air flow. From the filter element, the air is drawn into the air cleaner outlet duct and past the first air resonator. This resonator is actually the upper half of the air filter housing. Air flows through the duct, past the mass air flow (MAF) intake air temperature (IAT) sensor and into the second air resonator that is mounted directly on top of the engine. Air exiting the second resonator flows directly to the throttle body and into the engine.
