AIR INTAKE SYSTEM

The 4.2 Liter V8 supercharger (SC) engine air intake and distribution system comprises

1. Air filter box
2. Air intake
3. Porus duct
4. Air filter and filter box
5. Intake duct
6. Electronic throttle.

AIR FILTER BOX

The air filter box is located in the front of the engine bay on the inside of the right-hand (RH) front wing. Air is drawn from the air intake in the wing through a porous duct and into the air filter box. The filter box contains a paper air filter element.

AIR INTAKE DUCT

The air intake duct runs from the throttle body to the air filter box. The duct comprises 2 separate pieces. One piece runs from the air filter box to the front of the engine and the other from the front of the engine to the rear of the engine locating on the throttle body. The front half is manufactured from plastic and incorporates a number of resonator chambers. The rear part of the duct is manufactured from cast aluminum.
