🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Locate the airbox

• Open the hood and find the air filter box on the engine side of the intake system.
• It is the black plastic housing connected to the intake tube.

Step 2: Remove the airbox cover fasteners

• Use the T25 Torx driver to remove the airbox screws if your cover uses screws.
• If your cover uses spring clips instead, use the flat trim tool to release them carefully.
• Tip: Keep the fasteners together in a safe spot.

Step 3: Lift off the airbox lid

• Lift the top of the airbox straight up with your hands.
• Do not force it if it feels stuck. Check for any hidden clips or loose hoses.

Step 4: Remove the old air filter

• Pull the old filter straight out of the airbox.
• Use the shop vacuum to remove loose dust and debris from the airbox bottom.
• Wipe the sealing surface with a microfiber cloth.

Step 5: Install the new air filter

• Set the new filter into the airbox with the sealing edge fully seated.
• Make sure it sits flat all the way around.
• Tip: A crooked filter can let dirt in.

Step 6: Reinstall the airbox lid

• Place the airbox cover back on carefully.
• Align it so the tabs and edges fit correctly.
• Reinstall the T25 Torx screws or snap the clips back into place.
• Torque to snug only for plastic airbox screws; do not overtighten.
