Car wind deflectors are a device that is placed on the window of a car to deflect the air towards the vehicle while driving. Wind deflectors are usually made of transparent material such as plastic and are placed on the upper edge of the window.

Wind deflectors have various advantages, including the following:

1. Protection from wind: Wind deflectors help restrict the airflow towards the vehicle, which can improve driving stability and reduce noise while driving.
2. Protection from insects and debris: Wind deflectors can trap and deflect insects, dirt, snow, rain, and other impurities that can cause discomfort while driving.
3. Enhancement of appearance: Wind deflectors can add an aesthetic touch to the car, giving it a more modern and attractive exterior.
4. If you are a smoker and it's raining, you can have the window slightly open to be protected from the rain, while the smoke is directed outside by the wind deflector.
5. In the summer at the beach, when the car is exposed to high temperatures for hours, you can have the window partially open, covered by the wind deflector, to allow air circulation and prevent high temperatures inside the car.

Depending on the model of your car, search for the corresponding wind deflectors. The colors are usually transparent or dark tinted depending on your preferences. Installation is relatively easy and you can install them on both the front and rear windows.
