Abstract

An apparatus and a method are provided for a multiple inlet air box to communicate an airstream through an air filter to an air intake duct of an internal combustion engine of a vehicle. The multiple inlet air box is comprised of a housing that supports the air filter within an interior of the housing. A mount portion within the housing fixedly receives a base of the air filter. Multiple air inlets couple with corresponding air inlet ports of the vehicle to direct the airstream into the multiple inlet air box. A duct directs the airstream from the multiple air inlets to the interior of the housing. A conduit communicates the airstream from an interior of the air filter to the air intake duct of the internal combustion engine.

Claims (19)

1. An air box for an internal combustion engine of a vehicle, comprising:

a housing for supporting an air filter within an interior of the housing;

a duct for communicating an airstream to the air filter;

one or more air inlets to the duct for coupling with air inlet ports of the vehicle; and

a conduit for directing the airstream from the air filter to an air intake duct of the engine; and

surface features disposed on one or more of the housing and the duct configured to provide clearance with nearby components disposed on the engine.

2. The air box of claim 1 , wherein the duct includes a longitudinal groove configured to provide clearance for a hood prop when the hood of the vehicle is closed.

3. The air box of claim 2 , wherein the longitudinal groove includes a latch mechanism configured to retain the hood prop when the hood of the vehicle is closed.

4. The air box of claim 1 , wherein the edge portion is configured to be coupled with a flat surface of an engine control unit, such that the flat surface of the engine control unit encloses the interior.

5. The air box of claim 4 , wherein the flat surface is configured to be placed into direct contact with the airstream, such that the airstream transfers heat away from the engine control unit.

6. The air box of claim 4 , wherein the edge portion is configured to receive a multiplicity of fasteners to attach the engine control unit or the flat panel to the housing.

7. A method for an air box for an internal combustion engine of a vehicle, comprising:

applying a filter oil composition to an air filter;

installing the air filter within an interior of a housing of the air box;

installing the air box within an engine bay of the vehicle;

coupling one or more air inlets of the air box with air inlet ports of the vehicle;

routing a conduit from the air box to an air intake duct of the engine; and

fastening a flat surface of an engine control unit to an edge portion surrounding an opening to the interior of the housing.

8. The method of claim 7 , wherein fastening includes disposing a gasket or a seal on the edge portion.
