PURPOSE: A moisture infiltration arrester for an air cleaner is provided to prevent the air cleaner from deteriorating and reducing a life time and to keep engine power without severe exhaust gas by discharging moisture before the moisture passes through the element of the air cleaner. CONSTITUTION: An intake system includes an air cleaner(1), an intake pipe(5) and evacuator valves(14,15). The air cleaner embeds an element(3) for filtering impurities in a housing(2). The evacuator valves discharge moisture outside. The intake pipe includes an air diffuser(8) installing plural blades(10). Plural blades guide air to diffuse on the inner wall of the intake pipe. On driving an engine, air flows to the housing of the air cleaner through the intake pipe and a boot(4) and passes through the element to remove impurities. Before passing through the intake pipe, air passes through a section enlargement pipe(6) and diffuses on the inner wall of the section enlargement pipe along the blades. Thus, moisture included in the air is condensed on the inner wall of the section enlargement pipe and discharged outside through evacuator valves.
