APR Carbon Fiber Intake for Audi B8 S4/S5 3.0T Back Tube
The OEM intake system includes resonators in the hose connecting the air box to the throttle body designed to reduce supercharger whine. The APR intake system in Stage 1 form replaces the factory air box and filter, and will deliver roughly 11 AWHP over stock. The Stage 2 back pipe when combined with the Stage 1 Air box will increase power further to around 15 AWHP and will slightly increase intake supercharger whine.
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 proving 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.
The APR Intake System simplifies the airflow path and routes incoming air directly to the filter.
