Abstract
A pre-separator removes contaminants from dirty air and an air intake system of an automobile engine. The pre-separator includes a central body connected to a plurality of vanes, the central body including a leading nose-cone portion and a trailing nose-cone portion. An exit tube defines an outlet that is sized and positioned relative to the central body. The pre-separator is capable of easy packaging within the air intake system, while minimizing the restriction and maximizing horsepower of the engine. In one embodiment, the separation efficiency, the restriction, and acoustic tuning may be selectively controlled for the particular application.
