I just installed the WeatherTech Side Window Deflectors. They were a snap to install, and look great. The shipping was also fantastic. Ordered and 3 days later they were here.

There is more road noise if the window is only cracked.

closed all the way, or open all the way...same same on noise. However, if it is cracked just a little bit the sound comes straight up from the road and into the cabin. (doesnt bother me though)
