  • Patent number: 5472463
    Abstract: A pressure side integrated air filter assembly for a turbocharged engine includes an air filter carrier which is designed and arranged to receive an air filter element and which is adapted to mount to the intake manifold of the turbocharged engine. The air filter carrier which receives an air filtering element is disposed within the intake manifold and the intake manifold cover serves as the air filter cover. A peripheral flange on the air filter carrier is used to support the air filter assembly by being clamped between the intake manifold cover and the intake manifold. This peripheral flange substitutes for the intake manifold gasket. The air filter carrier and the air filter element each have a trapezoidal shape in cross section as a way to conserve space within the intake manifold.
