Wind Deflectors reduces Wind Noise ?

Hi,

Do wind deflectors reduces wind noise from the windows ?

I'm looking not only from the cosmetics point of these deflectors but is there any practical use ?

It seems to make car washing more difficult. :)

I guess your talkin' about the window ones not the sunroof one. I have one on my sunroof and it helps w/ the noise as do the window ones. I don't have 'em on my G but had them before. They work great, especially if you smoke (that shit-LOL) and are perfect for rainy days (all U-WA peeps)!!

I'm not sure I want them on my G, but some days I wish I had 'em!
