The WeatherTech 07-13 BMW X5 Front and Rear Side Window Deflectors are designed to provide protection from the elements while allowing fresh air to circulate into the vehicle. The dark smoke finish provides a sleek, stylish look and the deflectors are easy to install with no drilling required. The deflectors also help to reduce wind noise and keep the interior of the vehicle cooler. They are constructed from a high-grade, impact-resistant acrylic material that is UV and scratch-resistant. The deflectors allow the windows to be opened for fresh air circulation while keeping the rain and wind out.
