The Multiple Intake Air Filtration Device of this invention is a superior, highly efficient air cleaner that utilizes an array of multiple-intake cyclonic tubes spinning air at high speed to efficiently remove the specific sizes of dirt and other particulates that can be ingested in off-road and highway vehicle operations. This Multiple Intake Air Filtration Device is well-suited for use with both normally-aspirated engines and turbocharged engines. It is superior to automotive air cleaners that filter out dirt by use of a screen or porous media because it never becomes clogged as dirt and particulates are filtered out, and it is superior to devices that utilize only a single air flow through cyclonic tubes, because the device of this invention cleans intake air more efficiently while providing a strong flow of clean air to the engine or other component.
