Abstract: A Molded Air Intake System and Method for Internal Combustion Engines. The method of the present invention permits the single-shot molding of an air intake system, such as by roto-molding. The resultant air intake system has an internal pipe element and an external element, both of which are formed with superior molding tolerances. The internal pipe element is defined by an inner mold form that is insertable and removable from an external mold form. The final molded part defines an outer wall and an inner wall and an MAFS mounting pad having inner and outer apertures formed therethrough.

Abstract: A Twist-interlocking Engine Housing and Air Filter System and Method is disclosed. The filter assembly provides unequaled ease of installation and removal, as well as superior sealing between the housing and the filter assembly. For installation, the user needs only to insert the filter into the housing and then give the filter assembly a one-quarter turn or less to lock the filter assembly into the housing. There are features within the filter base that snap-locks the filter in place to resist inadvertent loosening. Finally, the housing and filter are designed so that the outer flange of the filter base is recessed into the side of the housing in order to prevent the intrusion of unwanted grime and/or fluids.
