4 important things to know about deflectors (sun, vent and window)

Installing wind deflectors on cars is a great way to keep rain, sleet and snow out of your open windows and the sunroof is a great option when you need fresh air even in bad weather. They can also help you get out into fresh air without distractions. Deflectors are also great for minimizing wind noise and creating a more comfortable environment when your windows are down.

Types of deflectors

While there are technically four types of deflectors—sun, vent, window, and bug deflectors—we'll only look specifically at the first three, leaving the bugs for another time. Sun, vent and window deflectors are used for the same basic functions - to protect the vehicle interior from the sun, air and liquids such as rain or snow.

How do deflectors work?

Deflectors work on a very simple principle of aerodynamics, changing the flow of air and water around your vehicle. They are precisely engineered to reshape your car's aerodynamic contour by redirecting air and fluids to the sides of the car while maintaining the ventilation provided by open windows and vents.

What are deflectors made of?

The highest quality windscreens are made from acrylic glass and usually contain a tint to help reduce glare. Designed specifically for your vehicle make and model, they fit precisely to window ducts and air vents for a seamless installation. Some side window deflectors are made of high quality 3 mm thick acrylic plastic.

Installation tips

Luckily, deflectors are very easy to install and require no mechanical knowledge or tools other than a flathead screwdriver. Most deflectors are simply inserted into a channel in a door or vent, while some are designed to be installed with special adhesive to hold them in place. Even if you use the paste type, they are still very easy to set up and will only work in one particular way.

Benefits of side window deflectors

• Elegant aerodynamic style
• Usually installed in the window channel
• Keeps side windows dry in the rain
• Offers the ultimate in fresh air enjoyment
• Keeps the car interior cool when parked

The deflectors that fit into the window channel are so individual that it's rare to say they weren't factory installed. This relatively inexpensive upgrade can greatly increase the enjoyment of your car.
