Purpose and Function of the Insulation Insert

The presented insulation insert is dedicated to the rear right part of the door in Mercedes W163 models. Its purpose is to create an additional barrier between the outer panel and the upholstery, which translates to:

• reduction of road noise and wind noise in the cabin,
• limitation of vibration transfer from the door structure,
• stabilization of internal door components, such as upholstery or hardware mounts.

Thanks to its factory shape, the insert works with the door structure, supporting the correct positioning of the upholstery and other components installed in this area.

Construction and Fit for the Rear Right Side

The element has been developed specifically for vehicle placement: rear – right side, meaning its geometry and support points are adapted to the specific door configuration. This solution:

• facilitates installation without the need for modifications,
• ensures proper adhesion to the inner door panel,
• minimizes the risk of looseness and unwanted resonances.

As a component from the Doors and Door Panels group, the insert works with factory mounts and the door's supporting structure, contributing to the preservation of the original rigidity and operating characteristics of the entire door module.

Performance Characteristics and Installation Benefits

The application of a dedicated insulation insert in the rear right part of the body allows for the restoration or maintenance of the factory level of acoustic comfort. In practice, this means:

• more comfortable travel conditions for rear seat passengers,
• better cabin separation from noise from the wheel arch and wheel area,
• limitation of small contaminants entering the door's internal structure.

The insulation insert is particularly useful for work related to upholstery replacement, window regulator repair, or door restoration after a collision, when it is necessary to recreate the complete internal structure.

Product Condition and Service Application

The offered element is in used condition, making it a practical service solution for everyday vehicles. Choosing an original part from disassembly allows for compliance with the factory door construction while limiting repair costs compared to new components.

The product is suitable for both standard replacement of damaged insulation and for more extensive bodywork and workshop tasks where recreating the complete package of internal door elements is important.
