🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Open the air filter housing

• Locate the air cleaner box on top of the engine bay.
• Use a Phillips screwdriver to loosen any housing screws if equipped.
• Release the retaining clips by hand or use a trim clip tool if they are tight.
• Lift the lid gently.

Step 2: Remove the old air filter

• Lift the old filter straight out of the air box.
• Note how the filter sits in the housing so the new one goes in the same way.
• Check the air box for leaves, dust, or debris.

Step 3: Clean the housing

• Wipe out loose dirt inside the air box with a clean cloth.
• Do not let dirt fall into the intake tube.
• A clean seal helps prevent dust leaks.

Step 4: Install the new air filter

• Place the new engine air filter into the housing the same way the old one was seated.
• Make sure the filter edge sits flat all the way around.

Step 5: Reinstall the air box lid

• Lower the lid straight down without pinching the filter.
• Reinstall and tighten any screws with a Phillips screwdriver.
• Snap the retaining clips closed by hand.
• Listen for each clip to click.

Step 6: Final check

• Make sure the air box is fully closed and the intake tube is connected.
• Close the hood.
