Purpose and Compatibility

The offered air duct has been specifically designed for BMW 3 Series models of the E90, E91, E92, and E93 generation in the LCI version, intended for the rear right side of the vehicle. The component's design is adapted to the interior geometry of these body styles, allowing for correct routing of airflow from the central heating system to the vents in the rear passenger area.

The placement designated as rear right means the part works with the right side of the center console and the rear air vents, ensuring a stable fit without the need for modifications to factory mounting points.

Function in the Heating and Ventilation System

The air duct plays a crucial role in distributing air from the heating and air conditioning unit to the rear of the cabin. A correctly selected component:

• directs air from the central duct to the vents near the rear seat on the right side,
• minimizes flow losses due to its matched cross-section and shape,
• supports even heating and cooling of the rear passenger space,
• minimizes the risk of airflow noise resulting from leaks or improper installation.

By using an original component in the BMW 3 Series LCI HVAC system, the designed airflow parameters are maintained, contributing to the comfort of rear passengers.

Characteristics of an Original BMW Part

As an original BMW component, the air duct is made from a material selected for its resistance to temperature changes and typical operational loads within the cabin. Its shape and mounting points comply with factory documentation, facilitating installation in place of a damaged or missing part without requiring modifications.

The manufacturer's system designation and assigned replacement numbers allow for unambiguous identification of the part in BMW catalogs and service systems, which is important when selecting the correct part for a specific vehicle configuration.

Application of Used Parts in BMW Service

Choosing a used air duct for the BMW 3 Series LCI is a solution that maintains consistency with the original heating system while optimizing repair costs. This type of component is particularly useful in situations where:

• the duct has been mechanically damaged during center console removal,
• cracks have occurred due to wear and tear or previous interior repairs,
• parts are missing after incomplete installation of additional equipment.

By retaining the original geometry and mounting points, installation proceeds predictably for an experienced mechanic or a service center specializing in the BMW brand.
