The main components of the intake and air distribution system of the V6 engine with a displacement of 4.0 liters:
- air filter housing
- air intake
- Intake manifold
- Electronic throttle
Air filter housing
The air filter housing is located in the front of the engine compartment on the inside of the right front fender. Air enters the air filter housing from the air intake in the wing through a channel in the wing.
After air filter housing and mass air flow/intake air temperature sensor (MAF/IAT) the resonator is located.
Intake manifold
Air intake manifold
| Item name | Spare part number | Description |
| 1 | - | Intake manifold |
| 2 | - | Electronic throttle |
| 3 | - | Intake manifold control valve (IMTV) |
The intake manifold is located at the top of the engine between the two cylinder banks. The manifold is made of aluminum alloy. The intake manifold includes a central reservoir with 6 channels leading to the intake ports of the cylinder heads.
Intake manifold control valve (IMTV)

Intake manifold control valve
intake manifold control valve (IMTV) located on the right front side of the air intake manifold. The IMTV valve is controlled by PWM signals sent by the ECM For more information, refer to Electronic Engine Controls (303-14A Electronic Engine Controls - 4.0L). IMTV moves the plate inside the intake manifold, allowing or blocking the sound pulses that are transmitted between the individual halves of the manifold. In fact, this leads to the expansion of the intake ducts and the optimization of torque at low revs.
