Abstract: An air filter retention interface for use with an internal combustion engine is disclosed. The interface is substantially secured in an opening of a wall and the interface attaches to an air filter at the front end of the interface and an air intake tube on the back end of the interface. The interface has a filter sleeve and a filter base. During operation of the engine the filter sleeve is disposed through the opening in the wall such that the wall is between beads disposed on the external surface of the filter sleeve and the filter base thereby substantially securing the interface in place and the front end of the filter base is attached to the filter and the back end of the filter base is attached to the air intake tube and air passes through the filter then through the filter base and filter sleeve and then into the air intake tube and toward the engine.

Abstract: A vent insert is disclosed for use with an automotive turbocharger system. The vent has a substantially cylindrical hollow tube with a first end for seating the vent and a second open end. The first end has a rim around an opening. The second end of the vent has an angled opening that faces away from the direction of the gas flow when the vent insert is operating within the turbocharger system. There are a plurality of protrusions extending outward from the outside surface of the vent to assist in keeping the vent insert in place in the turbocharger system.

Abstract: A sealed intake air system incorporates a positive connection seal interface between the air filter and the airbox with captive fasteners to provide a positive connection between the air filter and the one-piece airbox.

Abstract: An interface air filter and assembly for use with an internal combustion engine is disclosed. The assembly has a housing having an air intake port and an opening. There is an air filter assembly with an air filter having a closed end and an open end and a reducing coupling. The reducing coupling has a first end with a first engaging member having an external circumference and outer surface, a second end with a second engaging member having an external circumference less than the first engaging member external circumference, and the second engaging member has an inner surface. The first end of the reducing coupling is attached to the open end of the air filter. The air filter assembly is in contact with the housing such that the air filter resides within the housing and the outer surface of the first engaging member engages the housing.
