Abstract: An assembly of components for coupling an air filtration device to an engine is disclosed. The assembly includes an adapter component having first and second adapter ends, and a hose having first and second bends and first and second hose ends, where the first hose end is configured for being coupled to an output terminal of the air filtration device and the second hose end is capable of being coupled to the first adapter end of the adapter component. The adapter component further includes a straight tubular section leading up to the second adapter end so that, when the adapter component is assembled with respect to the engine, air is directed from the straight tubular section into the engine.

Abstract: A filtering apparatus and method of operating a filtering device are disclosed. The apparatus includes a housing having an inlet and an outlet and at least first and second cavities that are coupled to the inlet and outlet, respectively, where an input fluid within the first cavity has an input pressure and an output fluid within the second cavity has an output pressure. The apparatus additionally includes a filter supported within the housing, where at least a portion of the filter extends along an axis within the housing, and the filter at least partly separates the cavities from one another. The apparatus further includes a device capable of determining whether the input pressure exceeds the output pressure by an amount and providing an indication thereof, the device being supported by the housing and extending into the housing along the axis and at least partly into a void within the filter.
