Device for filtering the intake air of internal combustion engines

Device for filtering the intake air of internal combustion engines, including a tubular housing (2) for at least a filtering cartridge (3) fixed at an end by means of support means (4) provided with an inlet opening (5) and fit to support said housing (2) in correspondence of a lower opening (9) thereof, said device (1) being characterized in that said filtering cartridge (3) is fixed to said support means (4), near the edges of said opening (5) so forming therewith a single body, and it is internally provided with air deflectors (6) fixed at the free end of said filtering cartridge (3);

• said device (1) comprising duct means (8) centrally provided with an outflow opening (7) and removably fixed to an upper opening (10) of said tubular housing (2) by means of fastener (15);
• the tubular housing (2) being made of carbon fiber and being a heat insulator between the external environment and the air flow passing through;
• the air flow coming from said opening (5) is forced by said air deflectors (6) to pass through said filtering cartridge (3) and comes out from said device (1) through the outflow opening (7), passing through the space between said filtering cartridge (3) and the external housing (2).
