An intake system for removing particles from air entering an engine, in which the intake air in an intake duct is divided into a primary airstream which flows upwardly at a sharp angle from the intake stream and into the engine inlet, and a secondary airstream which flows directly rearwardly with the particles to be removed, into a plenum where the particles are collected. A third airstream is formed which flows forwardly from the plenum beneath and at the sides of the intake duct, then upwardly around the sides of the intake duct and into the engine inlet.
