Genuine BMW 51-48-8-402-390 Front Right Door Panel Insulation

The Genuine BMW door panel insulation is a factory OEM sound-deadening panel designed to reduce road noise and protect the interior cabin environment. This insulation panel fits behind the door trim panel, creating an effective vapor barrier that helps keep moisture, wind noise, and unwanted sounds from entering the passenger compartment.

Key Features:

• Genuine BMW OEM part ensuring exact fit and quality
• Front right (passenger side) door location
• Functions as both sound insulation and vapor barrier
• Helps reduce road noise and wind noise intrusion
• May require replacement after window regulator service
• Direct replacement for worn or damaged original insulation

This insulation panel is commonly replaced during door panel removal for window regulator repairs or other interior door work. Installing a new insulation panel restores the factory sound-deadening properties and protects against moisture infiltration.
