Air filter with filtered cap

Abstract

An apparatus and methods are provided for a filtered cap air filter configured to be coupled with an air intake system of an internal combustion engine. The filtered cap air filter comprises a filter medium that is retained between a base and a filtered cap. The filter medium and the filtered cap are fabricated to remove contaminants and particulate matter from an intake airstream. In some embodiments, the filter medium and filtered cap may be configured to be treated with a filter oil composition to enhance air cleaning properties of the filter media. Wire supports may be incorporated into the filter medium and filtered cap to provide additional strength and durability to the filtered cap air filter. The base includes a flange and an opening that form an airtight connection between the filtered cap air filter and an air intake duct of the air intake system.
