Thule Wingbar Whistle Eliminators are designed to eliminate the high-pitched whistling that develops on Wingbar Evo 118 (47") crossmembers. They are a better alternative to wrapping with elastic as they look better and can be pushed out of the way of any other mounts such as bicycle, luggage, and more.
The end caps are designed to fit a 2018 Subaru WRX, but with a minor adjustment they can be added or removed based on your car's setup. Also, just mirror the current end piece in your slicer to make it fit the passenger side.
The center piece fits almost anywhere on the bar. However, it does not slide as easily against the end mounts as the end piece is designed to do.
The unit clips onto the groove under the bar and fits snugly against the rubber piece on top.
