What Are Car Wind Deflectors And Why Do I Need Them?


What are wind deflectors?

Driving with your window down in rain or at higher speeds can cause discomfort inside a car with both wind noise and spray affecting you and your passengers. Wind Deflectors work by simply deflecting rain and wind away from your car windows making the interior a much more comfortable environment.

How do they work?

They work on the principle that an open window alters a vehicle’s aerodynamics in a way that draws fast-moving air into the car. The result is amplified streaming winds persistently buffeting both driver and passengers and vastly increased road noise.

Window Deflectors help lessen these problems by slightly changing a vehicle’s aerodynamic contour. When wind hits the deflectors it is redirected over the open windows and around the sides of the vehicle, preventing it from streaming in through the window. Being able to keep your car well ventilated reduces the need for the use of air conditioning, which in turn can reduce fuel consumption.

What are they made from?

Wind Deflectors are precision made to the highest standards using acrylic glass. They are usually slightly tinted to help reduce glare. They are car make and model specific and are designed to fit into the window channels of a car door frame for a seamless installation. Each model is designed to suit the contours of the vehicle.

How are they fitted?

They are straightforward to fit without any mechanical knowledge or particular tools and simply clip into the seal at the top of the car door with the aid of a flat head screwdriver.

Wind Deflectors are ideal if you have pets as they help to get rid of stale air by improving ventilation. If you leave your pet in the car and need to leave the windows open the deflectors ensure that rain and damp cannot enter through the open windows. Deflectors also help to prevent misting of car windows when it rains; they help reduce winter condensation and they also reduce sun glare through side windows.

How much do they cost?

The deflectors are usually sold in pairs and cost between £30-£50 depending on the make and model.

The main benefits of fitting Wind Deflectors are:

  • Reducing wind and noise
  • Tinted to reduce glare

  1. Wind deflectors are really just cosmetic. How often do you need to open your window just a little in the rain? Only if you’re a smoker.

    Reducing wind noise is a claim to sell more junk.
    These are one of the most useless accessory since those “deer sirens”.
