A contaminant separation device 20 for reducing flow of contaminants to the air duct 22 of a vehicle engine air induction system 12. The planar lower surface 40, 42 induce a laminar flow 60 beneath the device of contaminated air and an opening 44 permits a clean air flow 62 to separate from the laminar flow and reach the air duct. A flow guidance plate 52 may be included towards the back of the device, extending diagonally upwards and forwards. The device prevents dust, ice, water and other contaminants from entering the air duct. Low pressure above the surface and high pressure below cause the induction of low inertia air through the inlet. With the device positioned above the flow heavier contaminant particles are restricted from entering the inlet due to gravity. A method extracting clean air from contaminated air, an air induction system for a vehicle and a vehicle using such a device are also disclosed.
