Abstract
The present invention relates to a component for an internal combustion engine of an automobile having reduced NVH properties. The component has a shell formed with a plastic composite material. The shell defines an inlet port, an outlet port, an outer surface and an inner surface. The inner surface defines an inner cavity to allow air passage to the internal combustion engine. A damping layer is disposed on the outer surface such that damping layer substantially dampens the noise emitted from the component.
