As simple as an Isuzu air deflector appears to be, there is actually a significant amount of engineering involved in its design. The primary purpose of an Isuzu air deflector is to redirect air, and it is shaped very precisely to achieve this goal. When you use an Isuzu air deflector on the hood, you redirect the air that would normally flow directly into the windshield, shifting it up and over the vehicle. Thus, you also deflect what would normally be carried in the airflow, such as insects, which cause a smeary, difficult to clean mess, road debris, like gravel and small stones that can ding and scratch, dulling the surface of the hood and damaging the windshield, and even snow and rain, helping to make driving during bad weather that much safer. Installing an Isuzu air deflector above the rear window help to keep the rear window cleaner as well, helping to keep visibility at its best. Using the type of Isuzu air deflector that is made for the side windows can serve to prevent rain and wind from coming in when the window is open, and also reduces the noise. When all of these types of Isuzu air deflector are used together, there is an added benefit, which is to make the vehicle more aerodynamic. This is an important factor, as it influences both handling and fuel consumption. When the vehicle is more aerodynamic, due to the use of an Isuzu air deflector set, it travels more smoothly through the oncoming air, and is less subject to being pushed in one direction or the other by the wind, making steering much easier, especially when being passed by those big 18-wheelers on the highway. Less wind resistance means that the engine doesn't have to work so hard to propel the vehicle forward, which decreases its fuel demand.
