🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Open the air filter housing

• Pop the hood and locate the black plastic air box on top of the engine bay.
• Use your hands to release the metal clips or use a flathead screwdriver if a clip is tight.
• If your housing has screws, remove them with a flathead screwdriver.

Step 2: Lift the air box cover

• Carefully lift the top cover straight up with both hands.
• Do not yank it up fast, because the intake tube may still be seated tightly.
• Lift slowly to avoid breaking clips.

Step 3: Remove the old air filter

• Pull the old filter out of the air box by hand.
• Check the air box for leaves, dirt, or debris.
• Use a shop towel to wipe out any loose dirt.

Step 4: Install the new air filter

• Place the new engine air filter into the housing in the same direction as the old one.
• Make sure the filter sits flat all the way around.
• Do not force it; it should seat naturally.

Step 5: Reinstall the air box cover

• Lower the cover back into position.
• Make sure the intake tube is aligned properly and the cover edge is fully seated.
• Reinstall the clips or screws using your flathead screwdriver.
• Torque to snug only if screws are present; do not overtighten plastic fasteners.

Step 6: Final check

• Confirm the housing is fully closed and latched on all sides.
• Start the engine and listen for any unusual air leaks or whistling.
• If everything sounds normal, the job is done.
