Step-by-Step Instructions

Step 1: Locate the Air Filter Housing

Open your hood and locate the air filter housing. It's typically a large, black plastic box on top of or to the side of the engine. Consult your owner's manual if you're unsure of its location.

Step 2: Remove the Housing Cover

The housing cover is usually held on with 2-4 clips or bolts. Use your screwdriver to remove these fasteners and set them aside in a safe place.

Step 3: Remove the Old Air Filter

Carefully lift the housing cover and remove the old air filter. Note its orientation so you can install the new one correctly.

Step 4: Inspect the Housing

While the housing is open, use your flashlight to look inside. If there's excessive dust or debris, gently wipe it out with a clean rag.

Step 5: Install the New Air Filter

Insert the new air filter into the housing, ensuring it's oriented correctly (the airflow direction is usually marked on the filter frame). The filter should fit snugly without forcing.

Step 6: Reinstall the Housing Cover

Replace the housing cover and reinstall the clips or bolts. Tighten them firmly but do not over-tighten, as this can crack the plastic housing.

Step 7: Close the Hood

Close your hood and you're done. Your engine now has improved airflow and will run more efficiently.
