Step-by-Step Instructions

Follow these steps carefully

1

Locate the Air Filter Box

Open the hood and locate the rectangular air filter housing box, usually near the front of the engine bay on the driver's side. Informational DIY. EZ Car Fix is not a shop.

2

Open the Air Filter Housing

Release the metal clips or unfasten the latches securing the air filter box lid. Some models use screws — use the appropriate screwdriver or socket.

3

Remove the Old Filter

Lift the lid and carefully remove the old air filter. Note the orientation so the new filter goes in the same direction (filter pleats typically face the engine).

4

Clean the Housing

Wipe out any leaves, dirt, or debris from inside the air filter box with a clean rag or vacuum. A dirty housing will immediately contaminate the new filter.

5

Install the New Filter

Place the new air filter into the housing, matching the orientation of the old one. Ensure it seats flat with no gaps around the edges.

6

Close and Secure

Reinstall the lid, ensuring the tabs align properly. Reconnect the clips, latches, or screws. Start the engine and verify there are no unusual sounds or air leaks.

All Done!

Test your repair before closing everything up. If something doesn't work right, double-check your steps.

⚠️ Common Mistakes to Avoid

  • • Forgetting to disconnect the battery before starting the repair
  • • Using incorrect tools, leading to damaged components
  • • Not properly sealing the air filter housing, causing air leaks
