Air Filter Element: Description and Operation
Intake Air System
Dirt and dust particles in the air are abrasive and, if allowed to enter the engine with the intake air, can cause significant damage in a relatively short
period of time. The air cleaner assembly contains a paper filter element that removes these particles from the intake air.
Other intake system components include the throttle body, bypass air control valve, dynamic chamber w/shutter valve (VRIS - variable resonance
induction system), extension manifolds, and intake manifold w/swirl control valve (TICS - triple induction control system). These components are listed
separately in this section.
