Abstract
An intake system () for a vehicle internal combustion engine is provided in which a first air intake duct (), having an air intake inlet () to inhale external air, is connected to an air cleaner box (). A second air intake duct () is also connected to the air cleaner box. The air intake inlet is closer to the air cleaner box than the second air intake duct is. The cross section area of a second air intake duct is greater than the cross section area of the first air intake duct. The center axis of the second air intake duct at an end on the side of a second air intake opening () intersects with the center axis of the first air intake duct at an end on the side of a first air intake opening ().
