ABSTRACT:
The engine air intake apparatus comprises a planar base plate incorporating a curved duct which lies in the plane of the base member initially and then curves inwardly therethrough. The inwardly curved portion of the duct lies toward a trailing edge of the base plate member and is covered by a cover plate member which seats onto and over the trailing end portion of the base plate member in a parallel plane slightly above the plane of the base plate member. When mounted onto the hood of a vehicle, the leading edge of the base plate member, which is slightly elevated above the level of the hood, provides a leading end splitter plow arrangement to the apparatus for removing hood surface water from the air stream flowing along the hood. The duct incorporates a further water removal apparatus comprising an interior separator plate and drain at the trailing end of the curve within the duct for collecting airborne water particles thereon which are thrown off the air stream by centrifugal force as the air stream negotiates the curve and for eliminating the water particles from within the apparatus.
