Intended Use and Function of the Part

The rear right door seal strip in the BMW F20 is responsible for the airtight connection between the door edges and the body, as well as the proper guidance of the side window.

A properly selected seal limits the ingress of water, dust, and air drafts into the interior, and also reduces wind noise at higher speeds. The correct fit of this component is important for both acoustic comfort and the protection of upholstery and interior door elements.
