COMPONENT LOCATION

Intake Air Distribution And Filtering:

INTRODUCTION
The 4.2 Liter V8 engine air intake and distribution system comprises:
- Air filter box
- Air intake
- Intake manifold
- Electronic throttle

The air filter box is located in front of the LH (left-hand) front wheel, behind the wheel arch liner and contains a replaceable paper filter element.

Dirty air is drawn through the air intake which is located behind the radiator grill on the LH (left-hand) side and into the air filter box past the paper filter element. Clean air is then passed over the MAF (mass air flow) sensor located in the ducting directly behind the air filter box, through the electric throttle and up to the air intake manifold where it is distributed to the individual cylinders.

The intake manifold is located on top of the engine between the two engine banks. The manifold is manufactured from a composite material with metal insert fixings. The intake manifold comprises a central chamber with eight tracts leading to the inlet ports on the engine.
