Abstract: An apparatus and a method are provided for an air box configured to cool an engine control unit (ECU) by way of an airstream being communicated to an air intake system of an internal combustion engine of a vehicle. The air box is comprised of a housing to support an air filter within an interior of the housing. An opening in the housing fixedly receives at least one surface of the ECU to transfer heat from the ECU to the airstream. A mount portion within the housing receives the air filter. A conduit to a clean side of the air filter is configured to be coupled with the air intake system. An inlet to the housing is configured to couple with an air inlet duct of the vehicle so as to direct the airstream into the interior of the housing.

Abstract: An air box and methods are provided for communicating an airstream through an air filter to an air intake duct of an internal combustion engine of a vehicle. The 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 air box. A duct directs the airstream from the multiple air inlets to the interior of the housing and to the air filter. An opening into the housing exposes at least one surface of an electronic control unit (ECU) to the airstream for cooling of the ECU. A conduit communicates the airstream from an interior of the air filter to the air intake duct of the internal combustion engine.

Abstract: An air filter has an inner filtering body within an outer filtering body. The air filter is configured to fit inside a scoop and adjacent to the inlet opening of the scoop. By placing the air filter adjacent to the inlet opening of the scoop, the size of the air filter may be increased as compared to a traditional air filter which fits within the neck area of the scoop. As such, the surface area of the air filter may be increased to provide more air to an air intake system such as a carburetor, fuel injectors, throttle body, or the like, as compared the traditional air filter. The inner filtering body may be recessed inside or protrude from the outer filtering body. The inner filtering body may be coupled to the outer filtering body along the base of the air filter. The inner filtering body increases the surface area of the air filter so that more air may be provided to the air intake system of a vehicle.
