🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Open the air filter housing

• Use your hands and a flat trim tool if needed to release the airbox clips.
• Lift the cover slowly so you do not knock dirt into the intake.
• Keep the opening clean.

Step 2: Remove the old filter

• Pull the old engine air filter straight out of the airbox.
• Check the filter frame and the inside of the housing for leaves, dust, or debris.

Step 3: Clean the airbox

• Wipe out any loose dirt from the airbox using a clean cloth or your hand.
• Do not let debris fall into the intake tube.

Step 4: Install the new filter

• Place the new engine air filter into the housing in the same direction as the old one.
• Make sure it sits flat all the way around the edges.
• Seating it crooked can let dirty air bypass the filter.

Step 5: Close and secure the airbox

• Reinstall the airbox cover.
• Use your hands to snap the retaining clips back into place.
• Confirm the lid is fully seated and latched on all sides.
