Wind deflectors are accessories designed to redirect airflow around a vehicle, typically installed on windows or sunroofs. They help reduce wind noise and turbulence inside the cabin, making for a more comfortable driving experience. By allowing fresh air to enter while keeping rain and debris out, wind deflectors enhance ventilation without compromising protection. These devices are commonly made from durable materials like acrylic or polycarbonate and come in various styles to fit different vehicle models. Wind deflectors are popular among car enthusiasts and are often used in conjunction with other accessories to improve overall vehicle performance and comfort.
