A device for filtering the intake air of an internal combustion engine having an expansion box ( 110 ) with an opening ( 12 ) for the intake air to pass therethrough, has a filter fixed to the opening that includes a first tubular filtering element having an upper annular element ( 1 ) having an upper end of the first tubular filtering element fixed thereto. A second filtering element is peripherally fixed to the upper annular element, over an upper end of the first tubular filtering element. A lower support ( 4 ) has an annular housing ( 9 ) for receiving the lower end of the first tubular filtering element therein, and a flat flange ( 7 ) for fixing the filter to the expansion box. |
