How to Upgrade Air Filters for Enhanced Engine Sound

Upgrading your car’s air filter can enhance engine sound, giving your vehicle a more aggressive and sporty exhaust note. This is often achieved by increasing the airflow to the engine, which can also improve performance. Here’s a step-by-step guide to upgrading air filters for enhanced engine sound:

1. Understand the Basics

How Air Filters Affect Sound:

  • Airflow: Increased airflow can enhance the induction sound of the engine, making it louder and more aggressive.
  • Material and Design: Performance air filters are often made from materials like cotton gauze or foam, which allow more air to flow through compared to traditional paper filters.

2. Choose the Right Air Filter

Performance Air Filters:

  • K&N High-Flow Air Filters: Known for their high airflow and reusable design.
  • aFe Power Magnum FORCE Air Filters: Designed for maximum airflow and improved engine sound.
  • Spectre Performance Air Filters: Offer a balance between performance and cost.

Cold Air Intake Systems:

  • Benefits: A cold air intake system replaces the stock air intake with a system that draws cooler air from outside the engine bay. This not only enhances engine performance but also often results in a louder and deeper engine sound.
  • Popular Brands: K&N, aFe Power, Injen, and AEM.

3. Check Compatibility

Vehicle Specifications:

  • Consult the Manual: Refer to your vehicle’s owner’s manual to ensure compatibility with aftermarket euro filter or intake systems.
  • Check Fitment: Ensure the chosen air filter or intake system is designed for your specific make and model.

4. Gather Tools and Materials

Tools Needed:

  • Screwdrivers: Phillips and flathead screwdrivers for removing clamps and screws.
  • Wrenches: Socket set or adjustable wrenches for loosening bolts.
  • New Air Filter or Intake System: Ensure all components are included.

5. Remove the Old Air Filter

Step-by-Step Removal:

  1. Locate the Air Filter Housing: Typically found near the front or side of the engine bay.
  2. Open the Housing: Release the clips or screws holding the air filter housing in place.
  3. Remove the Old Air Filter: Take out the old filter and inspect the housing for dirt or debris. Clean if necessary.

6. Install the New Air Filter or Intake System

Installing a Performance Air Filter:

  1. Place the New Filter: Insert the new performance air filter into the housing, ensuring it fits snugly.
  2. Secure the Housing: Reattach the clips or screws to secure the air filter housing.

Installing a Cold Air Intake System:

  1. Follow Instructions: Refer to the manufacturer’s instructions for specific steps.
  2. Remove Stock Components: Remove the stock air intake components as per the instructions.
  3. Install the New Intake System: Fit the new intake system, ensuring all components are securely fastened and connected.
  4. Check Connections: Ensure all hose clamps and bolts are tightened properly.

7. Test the New Setup

Initial Start-Up:

  • Listen for Changes: Start the engine and listen for changes in the engine sound. You should hear a more pronounced and aggressive intake noise.
  • Check for Leaks: Ensure there are no air leaks around the filter or intake system.

Test Drive:

  • Performance Check: Take the car for a test drive to experience the enhanced engine sound and check for any performance improvements.
  • Monitor Engine Behavior: Ensure there are no unusual sounds or performance issues.

8. Maintenance and Care

Regular Cleaning:

  • Reusable Filters: Clean reusable air filters (like K&N) regularly according to the manufacturer’s instructions.
  • Inspect for Damage: Periodically check the filter and intake system for any signs of wear or damage.

Periodic Replacement:

  • Follow Guidelines: Replace disposable performance air filters according to the recommended intervals to maintain optimal performance and sound.


Upgrading your air filter or installing a cold air intake system can significantly enhance your engine’s sound, giving your car a more aggressive and sporty note. By following the steps outlined above, you can achieve this enhancement while also potentially improving engine performance. Regular maintenance and proper installation are key to ensuring lasting benefits and optimal engine health.
