AIR INTAKE SYSTEM DESCRIPTION
The function of the Air Intake System is to provide filtered air to the engine. The system uses a cleaner element mounted in a housing. The cleaner housing is remotely mounted and uses intake ducts to route the incoming air into the throttle body. The mass air flow (MAF) sensor is used to measure the air entering the engine.
