Claim:
An air box assembly comprising: an air box having an inlet opening and an outlet opening, the inlet opening formed on a top side of the air box and having a predetermined configuration adapted to receive air into the air box; a lid having a first filter surrounded by an outer frame, the outer frame adapted to substantially seal around the predetermined configuration of the inlet opening of the air box, the first filter adapted to substantially enclose the inlet opening of the air box so that air passing through the inlet opening is substantially filtered by the first filter before entering into the air box, where the lid has an inner frame between the first filter and the outer frame, the inner frame steps up to the outer frame so that the inner frame has a different waterline than the outer frame to substantially prevent water from penetrating the first filter; and a second filter adapted to seal around the outlet opening of the air box, the second filter adapted to substantially filter the air inside the air box before the air exit through the outlet opening of the air box.
