🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Open the air filter housing

• Locate the black plastic air box on the engine side of the engine bay.
• Use your hands to release the retaining clips on the air box lid.
• If a clip feels stuck, use the flat trim tool gently. A trim tool is a small plastic pry tool that helps release clips without damage.

Step 2: Remove the old filter

• Lift the air box lid carefully.
• Remove the old air filter by hand.
• Note how the filter sits in the housing so the new one goes in the same way.
• Take a quick photo first.

Step 3: Clean the housing

• Use a clean shop rag to wipe out dirt, leaves, and dust from the air box.
• Do not let debris fall into the intake tube.

Step 4: Install the new filter

• Place the new engine air filter into the housing the same way the old one came out.
• Make sure the filter sits flat all the way around.
• Check the edges twice.

Step 5: Close and secure the air box

• Lower the lid carefully.
• Use your hands to snap all retaining clips back into place.
• Make sure the lid is fully seated on all sides.
