AutoTecknic Dry Carbon Intake Air Ducts are designed to mount behind the front grills of your F90 M5 to provide a "ram-air" effect by utilizing the air intake motion to increase the static air pressure entering the intake manifold under the bonnet. This creates greater airflow throughout the engine by forcing in increased cooler air, resulting in lower engine temperature and cooler air going into the intake.
The AutoTecknic dry carbon intake air ducts will improve the overall performance of any intake system. The characteristics of carbon fiber also provide a lightweight and aesthetically appearance to the car's front end.
