The Audi S4 is known for its performance and luxury, but enthusiasts often look for ways to enhance its power and efficiency. One of the most popular modifications is installing a cold air intake system. In this article, we will compare three of the best cold air intake brands for the Audi S4: K&N, AEM, and BMC.
What is a Cold Air Intake?
A cold air intake (CAI) is an aftermarket engine component designed to improve engine performance by increasing airflow. By drawing cooler air from outside the engine bay, a CAI can help improve combustion efficiency, which can lead to increased horsepower and torque.
Benefits of Installing a Cold Air Intake
Installing a cold air intake on your Audi S4 can provide several benefits:
- Improved Performance: Increased airflow can lead to better engine performance.
- Enhanced Sound: Many cold air intakes produce a more aggressive engine sound.
