1. An engine air intake apparatus for use with a truck having a hood incorporating an engine air hood duct for providing an air flow stream to an engine of the truck comprising:

  • a planar base member having an outer surface;

    a curved duct partially defined by an inner longitudinally extending wall which lies in the plane of the base member outer surface initially at an entrance adjacent a leading end thereof and then curves inwardly into said intake apparatus to an opening, said curved duct further being defined by side and rear walls depending inwardly from said base member;

    mounting wall means formed with said base member for mounting said planar base member to said hood in a manner assuring fluid communication between the curved duct opening and said hood duct and with said planar base member being spaced adjacently above said hood surface;

    a cover plate attached to said planar base member which seats onto and over a trailing end portion of the base plate member over the inwardly curved portion of the duct, said cover plate having a leading lip disposed adjacently above the plane of the base plate member;

    said planar base member having a flange overhanging said mounting wall means and further incorporating a splitter plow arrangement at said leading end thereof between said base member flange and said hood surface to prevent hood surface water from entering said air flow stream; and

    a water particle separator wall disposed transversely to said air stream on said rear wall adjacent said opening for capturing water particles thrown off by the air flow stream as it negotiates said curved duct and eliminating said water particles from said apparatus.
