[ What is claimed is:] [1.] An air intake system for a vehicle engine, comprising:an air cleaner apparatus and a cylindrically-shaped, open, air intake funnel having a periphery, a duct part defining one end of said funnel and a flared opening defining another end thereof, said air intake funnel communicating a stream of air therethrough and into said engine, said air stream flowing in a direction from said flared opening to said duct part, said air cleaner apparatus comprising an inner frame having a flat part, an outer frame engaging said flat part and a filter therebetween, both said frames concentrically disposed to cover said flared opening of said funnel,said flared opening of said funnel formed by a lip part flaring away from a center of said funnel,said funnel including an annular flat part disposed below said flared opening and radially extending about said periphery beyond said lip part,wherein said inner frame flat part engages said flat part of said funnel so as to be coextensive therewith and to position said inner frame in a face-to-face relationship with said lip part, thereby forming a space between said lip part, said inner frame, and said flat part, wherein said air intake system is adapted to force said air stream across said flat part of said inner frame and said funnel before flowing to said flared opening, thereby causing an eddy current to be generated in said space, thereby generating a negative pressure area within said space, said negative pressure area creating a suction that improves a rate of air flow introduced into said engine.
