twister

I had those on my previous car, not a cheap stick-on but one of those from weathertech that goes inside of your window. Those have a very thin precision cut, so usually it never affected wind noise, no more than it was without it. I just checked in there, and ES350 deflectors are not available yet, but curious to find out if anybody else think their installation will disrupt the quiet design of ES350? I don't have any problems with my windows, just like it was pointed out by some other ES350 owners with a wind noise. Still not even sure if it will look good with deflectors, but curious if anybody has an opinion about it?

Usually these deflectors insert behind the rubbers around the top part of the window. In our case, it will probably force the window to seal really well, and will probably quieten the car further!
