ABSTRACT:
An internal combustion engine includes engine cylinders in an engine block with intake ports to deliver charged air to the cylinders. An intake manifold conducts intake charge to the intake ports. A noise cover encapsulates the intake manifold. The noise cover comprises a noise abatement element substantially covering the intake manifold to abate noise transmitted by the intake manifold and a shell to encapsulate the noise abatement element. The shell is comprised of first and second portions, fastened to each other by integral-to-the-shell fasteners, to secure the noise cover about the intake manifold without mounting the noise cover to a potential noise source.
