Audi RS4 B8 RS5 8T Intake Manifold Lower Section Right O/S 4.2 V8 079133109BB

Audi RS4 B8 RS5 8T Intake Manifold Lower Section Right O/S 4.2 V8 is an original intake system component designed for the right side of the V8 engine, specifically engineered for the high-performance RS4 B8 and RS5 8T models. Thanks to its factory-spec intake runner geometry, it ensures stable cylinder filling conditions, which translates into predictable engine operation and proper interaction with the engine control electronics. This is the ideal solution for users who want to maintain the structural integrity and performance characteristics of the stock 4.2 V8 engine.

Purpose and function in the 4.2 V8 engine

The presented lower right intake manifold is responsible for the even distribution of the air-fuel mixture to the corresponding cylinder bank of the V8 engine. Its design is adapted to the high RPMs and loads typical of the units installed in the RS4 B8 and RS5 8T, which helps maintain proper engine dynamics and smooth operation.

A properly selected intake manifold is crucial for:

• stable cylinder filling at various engine speeds,
• maintaining stock power and torque parameters,
• correct operation of the engine management system and sensors,
• reducing pressure drops within the intake system.

Construction and fitment for the V8 unit

The lower right intake manifold in the 4.2 V8 engine works in conjunction with other intake system components, creating a cohesive airflow path from the throttle body to the combustion chamber. The factory geometry and runner layout are optimized for the specific cylinder bank angle of the V8 configuration, which minimizes discrepancies in filling between individual cylinders.

By maintaining the original design:

• the correct positioning of ports and mounting points is preserved,
• compatibility with stock seals and accessories is ensured,
• the risk of leaks and improper installation is minimized.

Vehicle placement and installation aspects

This component is designed for installation on the right side of the engine, which is important both when selecting parts and planning service work. Correct identification of the installation side is essential for V8 engines, where the intake system is divided into two cylinder banks, and each manifold has a specific assigned position.

In practical terms, this means:

• the necessity of matching it to the correct cylinder bank,
• maintaining the factory routing of the intake runners,
• easier integration with existing engine accessories.

Characteristics of the used component

The offered intake manifold comes from the secondary market, allowing for an economical repair or restoration of the stock engine configuration. The used component retains its factory design specifications, making it suitable as a replacement for a damaged manifold in both daily-driven vehicles and cars prepared for intensive use.

Choosing an original, used intake manifold is particularly beneficial when you want to:

• maintain the stock performance parameters of the engine,
• avoid fitment issues associated with non-original solutions,
• maintain the structural consistency of the entire intake system.

Integration with other Audi intake system components

The lower right intake manifold works with the upper manifold sections, throttle body, intake hoses, and the engine management system. When replacing this component, it is worth checking the condition of the seals, vacuum lines, and other intake components to avoid leaks and disturbances in the operation of the 4.2 V8 unit.
