CTS Turbo Cold Air Intake Audi A4, A5, S4, S5, RS4, RS5 2017-2021

This CTS Turbo Air Intake is an open intake system for the Audi A4, A5 (2.0 TFSI), S4, S5, RS4, and RS5 B9.

This intake from CTS Turbo provides a power increase of 8 to 11 hp. Not only does this intake deliver more power, but you will also experience a sportier (louder) intake sound compared to the original.

This intake is developed with a 3.5-inch velocity stack in the air filter. This means that the airflow is optimized towards the intake tube. The intake kit includes an aluminum CNC-bent intake tube. This intake tube ensures optimal airflow of intake air towards the supercharger.

The included heat shield prevents engine heat from reaching the air filter. It also works together with the original air supply, ensuring a good flow of cool intake air.

The intake is designed to provide a power and torque increase across the entire rev range. Due to the size of the intake and the aluminum tubes, a stronger and sportier intake sound from the engine can also be heard.

The intake is delivered complete with all necessary mounting hardware.

• 6-inch air filter with 3.5-inch velocity stack
• Silicone connecting hose (the correct hose is supplied for all engines)
• Aluminum heat shield with rubber edging around the borders
• Enhanced intake sound of the supercharger
