Tools and Materials Needed

  • K&N cold air intake kit
  • Socket wrench set
  • Phillips and flathead screwdrivers

Preparation

Before starting the installation, ensure your vehicle is parked on a flat surface and the engine is cool. Gather all tools and materials needed for the installation process.

Step-by-Step Installation Process

Step 1: Remove the Engine Cover

Using a socket wrench, remove the bolts securing the engine cover. Carefully lift the cover off and set it aside.

Step 2: Disconnect the Mass Airflow Sensor

Locate the mass airflow sensor (MAF) connected to the factory intake. Gently disconnect the electrical connector by pressing the tab and pulling it off.

Step 3: Remove the Factory Intake System

Loosen the hose clamps securing the factory intake tubing using a screwdriver. Remove the tubing and the airbox by unscrewing any additional bolts. Set these components aside.

Step 4: Install the K&N Air Filter

Take the K&N air filter from the kit and install it into the new intake system. Ensure it fits snugly and is secured properly.

Step 5: Connect the New Intake Tubing

Attach the new intake tubing to the throttle body. Make sure the hose clamps are tightened to avoid any air leaks.

Step 6: Reconnect the Mass Airflow Sensor

Reconnect the mass airflow sensor by sliding the connector back into place until it clicks. This ensures a secure connection.

Step 7: Secure the Intake System

Once everything is connected, secure the intake system in place using any provided brackets and screws. Double-check all connections and ensure everything is tight.

Step 8: Replace the Engine Cover

Finally, place the engine cover back onto the engine bay and secure it with the bolts you removed earlier.

Testing Your Installation

After completing the installation, start your engine and let it idle for a few minutes. Check for any unusual sounds or leaks. Take your Audi S3 for a test drive to experience the immediate power gains!

Maintenance Tips

  • Regularly check the air filter and clean it as needed.
  • Inspect connections and clamps for tightness periodically.
  • Monitor engine performance and responsiveness.
