Integrated air induction system

This invention relates to an automotive air filter assembly (10), in particular, an assembly which includes an air flow chamber portion (12) and a liquid reservoir portion (14). The air flow portion includes a panel filter (32) for filtering air flowing to an engine. The panel filter (32) includes air filtration media and hydrocarbon absorption media to inhibit release of hydrocarbon vapours to the air on engine shut down. The air flow portion also may include resonance chambers for acoustic silencing purposes. The liquid reservoir portion (14) can include a pump (92) for delivery of fluid such as windshield washer fluid.
