Thinking about getting some Ventshades for my 2011.
Do these seem to have an impact on mpg?
Any impact on wind noise (with windows up)?
Thanks!

 

Had some on my Accord. no effect on noise or mileage that I could tell. They didn't do a whole lot to break up the windflow. They were, however, great for leaving the windows cracked without worrying about the interior getting wet.

They used to sell generic sized ones to put in front of your sunroof, but they seem to have disappeared in recent years.

 

No and no.

They allow you to crack your windows to let cool air in. That's pretty much it.

 

Actually, I've noticed a little more noise with the windows up.

But, less noise with the windows cracked open.

You just get used to it... and they're definitely worth a little noise for some fresh air. And oddly enough, an ever so slightly cooler car (isn't much, but blocks a little bit of heat from the sides).

 

Vent shades just add a new look to the car.It will no give more MPG for your car.Noise depends of the wind outside at highway speed.

 

Thanks all!
