Manifold, Intake: Description
The intake manifold is an injection molded nylon composite design. The intake manifold is sealed to the cylinder head using four individual press-in-place port silicone gaskets. Replace the gaskets whenever the intake manifold is removed from the engine. If the intake manifold is damaged or cracked, it must be replaced.
The intake manifold provides ports for Positive Crankcase Ventilation (PVC) and emissions control. The following components are attached to the intake manifold:
- Electronic Throttle Control (ETC)
- Fuel rail
- Fuel injectors
- Combination Manifold Air Pressure (MAP)/ Intake Air Temperature (IAT) sensor
- Evaporative emissions solenoid
The fuel injection fuel rail is made of high impact metal. The intake manifold can be serviced without removing the fuel injector rail. Always install new O-rings on the fuel injectors.
