Purpose and function in the intake system

This intake pipe is a component of the air intake system in the sporty Audi RS4 B8 generation with the 4.2 FSI CFSA petrol engine. It is responsible for directing the correct amount of air to the intake manifold, ensuring:

• stable airflow at high RPMs,
• proper operating conditions for the petrol engine,
• consistency with the factory characteristics of the FSI engine.

By maintaining the original geometry of the pipe, the intake system retains the correct flow parameters, which is particularly important in powerful naturally aspirated engines.

Construction and fitment for Audi RS4 B8

The pipe belongs to the Lines, hoses and pipes group, meaning it has been designed as a component that works with other intake parts in the engine bay. The design of the pipe is adapted to:

• the layout of components in the Audi RS4 B8 engine bay,
• mounting at factory body and accessory points,
• operation in high-temperature conditions typical for high-power petrol engines.

Such fitment facilitates installation and allows for maintaining the factory routing of the pipe, without the need to modify other system components.

Characteristics of the used component

The offered pipe is a used original Audi component, which in practice means it retains the factory specifications and compatibility with the CFSA petrol engine. For many users, this is a sensible solution when:

• repairing the intake system after mechanical damage,
• restoring the stock configuration after modifications,
• optimizing service costs while using OEM parts.

A used intake pipe allows you to maintain the integrity of the air supply system without the need to use aftermarket replacements with uncertain parameters.

Benefits of using an original intake pipe

Using an original intake pipe in the Audi RS4 B8 4.2 FSI CFSA brings a number of practical benefits:

• Factory fitment – compatibility with the mounting system and installation routing in the engine bay.
• Stable airflow – maintaining the petrol engine's operating parameters in accordance with the manufacturer's specifications.
• Consistency with other intake components – the pipe works with stock filter housings, manifolds, and accessories.

For a sports car like the RS4 B8, the proper condition and design of the intake pipe are important for both performance and the durability of the engine.
