US Patent 7114475 Air cleaner, valve cover and intake manifold assembly

An air cleaner, intake manifold, and valve cover are integrated together for attachment to a vehicle engine. The air cleaner is positioned directly between the intake manifold and valve cover to provide a compact induction module. The induction module is mounted to the engine as a single unit. A throttle body is also incorporated into the intake manifold. A tube interconnects the air cleaner and the throttle body. An air filter is installed within the air cleaner to remove contaminants from air prior to entry into the tube.
