Enbloc device for filtering the intake air of combustion engines

An enbloc device for filtering the intake air of internal combustion engines includes a filtering element (2) corrugated and peripherally fixed to a support mean (9). This latter includes at least a first element (3) and a second element (4) respectively having shaped edges, first (21) and second (22), for reproducing the peripheral profile of the filtering element (2) and fixed to this latter in a single block.
