Abstract: Some embodiments are directed to a deflector for use with a vehicle air intake system that directs air from a vehicle exterior to a vehicle interior. The deflector can include a base configured for attachment to a region of an interior wall of an air compartment adjacent a perimeter of a drain. The deflector can also include a barrier wall connected to the base and including an inner surface that is disposed over the drain when the base is attached to the interior wall of the air compartment. The barrier wall can be shaped to define a concavity between the drain and the inner surface. The barrier wall can define an air stream opening that is disposed to direct air traveling from the drain and through the concavity toward a section of the interior wall of the air compartment that opposes a shield.
