I installed the Honda OEM moonroof deflector and had the same experience. It did reduce the wind noise when the moonroof was open but when closed, the wind noise was greater. Since my moonroof is closed 99% of the time, I removed it. It is now in the garage rafters. Anyone in San Diego area can have it for $50. $165 retail...$120 at College Hills before $30 shipping.FYI it was installed incorrectly so once installed right it did cut down on the wind noise. But as mentioned it does still create additional wind noise that isn't there without the visor installed. I cut my losses and had it removed. I don't like additional road noise.
