Purpose and Function in the BMW i3 REx Intake System

The air intake hose, integrated with a noise silencer, is responsible for directing air to the combustion engine's supply system in the hybrid BMW i3 REx. The component's design was developed by BMW with the aim of reducing vibrations and flow noise, which is particularly important in an electric-combustion vehicle where acoustic comfort is a significant factor.

The appropriately selected shape and cross-section of the hose support:

• stable airflow to the REx combustion unit,
• reduction of unwanted turbulence in the intake duct,
• minimization of intake air noise thanks to the built-in silencer.

Construction and Advantages of the Original Intake Hose

The original air intake hose with silencer is made from a material selected for its resistance to temperature and operating conditions within the engine bay. The factory geometry of the connections facilitates installation at the original mounting points, without the need for modifications or adjustments.

Key benefits of using this component include:

• Full compatibility with the BMW i3 I01 REx intake system – maintaining factory airflow parameters.
• Consistency with other system components, such as the air filter housing or subsequent hose sections.
• Reduced risk of leaks compared to aftermarket alternatives with imprecise fitment.

Used Condition and Installation Aspects

The item is offered in a used condition, allowing for economical repair of the intake system while maintaining original manufacturing quality. The hose is designed for direct installation in place of the factory component, using standard mountings and clamps, which reduces service time and simplifies the mechanic's work.

Before installation, a standard check of the intake system for leaks and proper hose routing is recommended to fully utilize the factory noise damping properties and stable airflow.

Part Selection by Numbers and Integration with Other Components

As an original component from the Hoses, Tubes, and Pipes group, the air intake hose with silencer is linked to dedicated part numbers and interchangeable numbers, facilitating precise identification in BMW catalogs and service systems. This allows for safe selection of the part for a specific BMW i3 I01 REx configuration, minimizing the risk of ordering errors.

Replacement of the intake hose is particularly recommended in cases of:

• mechanical damage (cracks, abrasions, deformations),
• detected leaks in the intake system,
• problems with intake air noise originating from the REx unit area.
