APR Carbon Fiber Intake for Audi B8 S4/S5
The APR Carbon Fiber Intake System is an attractive high-performance upgrade designed to increase performance by letting the engine breathe more freely.The factory intake design has the foundation for excellent performance, but much of this is sacrificed in an effort to meet other design requirements. With requirements set forth for only supporting factory power output levels, low engine sound levels and long service intervals, there is plenty of room for improvement.
The APR Carbon Fiber Intake System increases performance primarily by improving mass airflow through the system while still providing adequate filtration. Expect greater horsepower and torque through the power band with a more direct and responsive feel upon pressing the throttle. Sounds from the engine are enhanced and some may even experience better fuel economy depending on driving style.

Non Collapsible Design
During APR's S5 4.2L FSI V8 Stage III Supercharger development, APR's Engineering Teams quickly realized the factory intake system was not suitable for the significantly increased demands set by the APR Supercharger unit. The factory rubber intake plenum would collapse under boost and rob the engine of precious airflow. In some cases, the factory rubber intake plenum would completely detach and seal off the intake system! Thankfully APR's intake system does not suffer this design characteristic making this intake system suitable for even the most demanding horsepower requirements!
Smooth and Direct Air Flow
The OEM intake system vents some of the incoming air into the engine bay and takes several twists and turns before the air ever reaches the engine. The intake system simplifies the intake system by directing all incoming air directly at the filter. This allows for faster throttle response and increased torque at all RPM's.
Benefits of the intake system include
- Increased horsepower.
- Increased torque.
- Sharper throttle response.
- Improved economy.
- Enhanced engine sound.
- Lowers intake air temperature.
- Attractive carbon fiber finish.
