What is the best angle for a wind deflector?

Whether you’re a seasoned motorist or a newbie behind the wheel, you’ve probably noticed those sleek, aerodynamic devices attached to the windows of some cars, known as wind deflectors. But do these wind deflectors serve any purpose beyond aesthetics? Are they worth the investment, especially in a place like the UK, where the weather can be quite unpredictable? In this blog, we will delve into the world of wind deflectors and explore their benefits, installation process, and the best angle to maximize their effectiveness in the UK.

Do Wind Deflectors Save Fuel?

One of the most common claims associated with wind deflectors is that they can improve fuel efficiency. In theory, wind deflectors are designed to reduce wind resistance, making your car more aerodynamic. When your vehicle encounters less resistance as it moves through the air, it requires less energy (fuel) to maintain a steady speed.

However, the impact of wind deflectors on fuel efficiency is relatively modest. The savings you can expect are typically around 1-2%, which, while not insignificant, may not justify the cost of the deflectors for some drivers. The actual fuel savings can vary depending on factors like your driving habits, the type of vehicle you own, and the specific design of the wind deflectors.

Do Wind Deflectors Really Work?

Wind deflectors are more than just a fancy accessory; they do serve a practical purpose. Here’s how they work:

Reducing Wind Noise 

Wind deflectors help redirect the airflow around your car’s windows, which can significantly reduce the noise caused by wind turbulence when driving at higher speeds. This can lead to a quieter and more comfortable driving experience, especially on motorways.

Ventilation and Fresh Air 

Wind deflectors allow you to crack your windows slightly even during rainy weather. This helps in ventilating your car, preventing the buildup of condensation, and allowing fresh air to circulate without letting rainwater in.

Reducing Sun Glare 

When driving in sunny conditions, wind deflectors can reduce sun glare, making it easier to see the road and reducing eye strain.

In summary, wind deflectors do indeed work, offering benefits that extend beyond fuel savings.

Where Do You Put Wind Deflector Clips?

Installing wind deflectors requires careful placement of clips or adhesive strips to secure them to your vehicle. The exact location can vary depending on your car’s make and model, as well as the design of the wind deflectors themselves. However, some general guidelines apply:

Front Wind Deflectors 

These are typically attached near the top of the front windows, just above the side mirrors. Clips or adhesive strips secure them in place.

Rear Wind Deflectors 

The placement of rear wind deflectors can vary, but they are usually installed near the top of the rear windows. Again, clips or adhesive strips are used for attachment.

Side Window Wind Deflectors 

These deflectors are designed for the side windows and are placed at the front edge of the window frame. Clips or adhesive strips secure them.

It’s crucial to follow the manufacturer’s instructions carefully to ensure the proper installation of wind deflectors. Incorrect placement can lead to poor performance and potential damage to your car’s windows.

How Do You Fit Wind Deflectors on a Car?

Fitting wind deflectors onto your car is a relatively straightforward process. Here’s a step-by-step guide:

Gather Your Tools 

You’ll need the wind deflectors, clips or adhesive strips (provided with the deflectors), a cleaning solution, and a microfiber cloth.

Clean the Window Frame 

Use the cleaning solution and microfiber cloth to thoroughly clean the window frame where you plan to attach the deflectors. Make sure the surface is dry and free from dirt or grease.

Position the Clips or Adhesive Strips 

Follow the manufacturer’s instructions to place the clips or adhesive strips onto the window frame. Be precise in their placement to ensure a secure fit.

Attach the Wind Deflectors 

Carefully align the wind deflectors with the clips or adhesive strips. Apply gentle pressure to secure them in place. Double-check their alignment to ensure they are level and symmetrical on both sides of the car.

Allow for Proper Bonding 

If you’ve used adhesive strips, it’s important to give them time to bond properly. Follow the manufacturer’s recommendations for drying or curing times.

Test and Adjust 

After installation, roll up and down the windows to ensure they move smoothly without any interference from the wind deflectors. Make any necessary adjustments if the deflectors are obstructing window movement.

Wind deflectors can be a valuable addition to your car, especially if you’re looking to reduce wind noise, improve ventilation, or enhance your driving comfort. While the fuel savings they offer may not be substantial, their overall benefits make them a worthwhile investment for many UK drivers. When installing wind deflectors, precision and attention to detail are key to ensuring they function correctly and complement your vehicle’s aesthetics. So, whether you’re braving the M25 or navigating the scenic routes of the Lake District, wind deflectors can be your trusted companion on the UK roads, enhancing your driving experience.
