A used BMW Hood Insulation / Sound Blanket, OEM part number 7380520, is available from a donor vehicle. This genuine part, also known as a sound blanket, helps reduce engine noise and heat transfer to the hood. It was removed from either a 540d xDrive or M550i xDrive. When the insulation degrades or sags, it can allow increased cabin noise and heat buildup under the hood.
