Purpose and function of the component

The presented air duct is designed specifically for Mercedes S-Class W221 and CL W216 models and operates in the rear part of the body on the right side. Its task is to guide and disperse air in a specific zone of the vehicle, using an integrated bottom deflector. This solution allows for:

• directing airflow within the rear part of the body,
• maintaining proper operating conditions for adjacent components,
• preserving the factory aerodynamics and the air circulation intended by the manufacturer.

Thanks to its dedicated placement in the vehicle, the component works with other ducts and covers to create a cohesive structural system.

Construction and fitment for Mercedes W221 / W216

The air duct with a bottom deflector has been developed as an original Mercedes part, which means that its shape, mounting points, and flow cross-sections are consistent with the factory technical documentation. In practice, this translates into:

• precise fitment with body elements and covers in the rear part of the vehicle,
• no need for modifications or adjustments of mounts during installation,
• maintaining the stiffness and stability of the system as intended by the manufacturer.

The placement on the right rear side of the vehicle allows for easy identification of the part during inspection or repair, and the duct design is adapted to the specific body geometry of the W221 and W216 models.

Characteristics of the used component

The offered air duct is a used component, sourced from dismantling, which allows for a reasonable cost while maintaining the original manufacturer quality. This type of part is particularly attractive for body repairs where compliance with the factory design and the ability to restore the original air duct routing are important. The used component is a good alternative to new parts, especially for older generations of premium vehicles.

Benefits of using an original air duct

Using an original air duct with a deflector in a Mercedes W221 / W216 brings a number of practical benefits:

• preservation of the factory design of the air routing system in the rear of the vehicle,
• certainty of fitment for the specific model and side of installation,
• reduced risk of improper airflow after repair,
• the possibility of aesthetically and technically correct restoration of the vehicle's original state.

For users who value structural consistency and driving comfort, choosing an original air duct is a safe and predictable solution in terms of operation.
