None at all. The first day, maybe. Installing the rainguards (OEM) requires that you pull down the weather stripping on the top of the window. Then, place the guard, which has 2 clips. After that, replace the stripping. However, this causes the windows to not close all the way. There was definitely noise then! However, you heat it a bit with a heat gun (or leave it out in the sun for a while) and it molds around those clips. Windows close perfectly now, and no noticeable road noise now.
