Abstract

An apparatus and a method are provided for an air box with an integrated air filter to communicate air flow from an exterior of the air filter to an air intake of an automobile engine. The air filter comprises a filter material that surrounds at least a portion of an interior cavity of the air filter. An end cap is affixed to a distal end of the filter material, and a wire support extends along at least a portion of the exterior surface of the filter material. The air box comprises a housing portion and a mount portion. The housing portion is configured to direct air drawn through the filter material into the interior cavity of the air filter and then into the air intake of the automobile engine. The mount portion is configured to support the air box and the air filter once installed within an automobile engine bay.

Claims (12)

1. A method for cleaning an air box with an integrated air filter that is installed within an engine bay of a vehicle, the method comprising:

removing an air intake conduit of an internal combustion engine from a conduit of the air box, the conduit including a flange and an opening into an interior cavity of the air filter, and the interior cavity being bounded by a circumferentially extending filter material and a distal end cap;

inserting a water hose through the opening into the interior cavity;

spraying water so as to flush contaminants from the filter material; and

allowing the water and contaminants to drain from a bottom of the air filter and exit the engine bay.

2. A method for cleaning an air box with an integrated air filter that is coupled with an internal combustion engine, the method comprising:

removing a flange comprising the air box from an air intake conduit of the internal combustion engine, the flange including an opening into an interior cavity of the integrated air filter, and the interior cavity being bounded by a circumferentially disposed filter material and a distal end cap;

inserting a water hose through the opening into the interior cavity;

spraying water onto an interior surface of the filter material; and

allowing the water and contaminants to drain from the integrated air filter and exit the air box.

3. The method of claim 2 , wherein spraying water includes flushing the contaminants from the filter material.

4. The method of claim 2 , wherein allowing further comprises allowing the water and contaminants to drain from a bottom portion of the air filter and exit an engine bay wherein the air box is installed.
