Purpose and Function in the Ventilation System

The presented air duct is specifically designed for installation in the rear of the vehicle, on the left side. It is responsible for directing air from the main air conditioning system to the vents intended for rear seat passengers, contributing to even temperature distribution throughout the cabin.

Thanks to its proper profile and fit to the center console, this component:

• directs air in a controlled manner, minimizing airflow losses,
• supports maintaining thermal comfort in the rear interior,
• ensures compatibility with the factory mounting system and upholstery shape.

Construction and Fit for Mercedes W205

The air duct is structurally prepared to work with the factory ventilation system in the Mercedes C-Class W205 generation. This means its geometry, mounting points, and connection diameters are adapted to the original ducts and center console elements.

This solution allows for:

• trouble-free installation in place of the factory duct without structural modifications,
• maintaining the seal of connections with other system components,
• preserving the factory routing of air ducts in the rear of the vehicle.

Vehicle Placement and Installation Aspects

The component is intended for installation in the rear interior, on the left side, in the center console area directing air to the rear passenger vents. This placement requires observing the correct order of removing covers and upholstery to avoid damaging other components.

When planning the installation, it is worth paying attention to:

• correct positioning of the duct relative to factory guides and clips,
• precise seating at the contact points with other air ducts,
• checking that the rear vents operate evenly and without additional noise after installation.

Characteristics as a Used Part

As a used part, the air duct is a sensible solution for users who want to restore full ventilation system functionality while maintaining a favorable cost-to-quality ratio. Its original origin promotes compatibility with factory interior elements and the air conditioning system.

Choosing such a component allows for:

• maintaining consistency with other HVAC system components,
• reducing the risk of fitment issues typical of universal aftermarket replacements,
• restoring proper airflow to the rear of the cabin without interfering with the vehicle's structure.
