description 2An emission control device for an air induction system of an internal combustion engine having high adsorption capacity, yet low flow resistance is disclosed. The AIS emission control device comprises a first case including an outlet-opening connected to an intake manifold of the engine; a second case including an inlet-opening for the intake air; and an adsorbent element positioned in a plane across the intake airflow, wherein the adsorbent element has an opening area such that the control device has a pressure drop of less than about 1 inch HO at the air flow rate of about 300 cfm and % reduction in vapor emission of at least about 75% after one day of the vapor generation rate of about 220 mg/day.
