🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Open the airbox

• Locate the engine air filter box on the top of the engine bay.
• Use the Torx T25 screwdriver to remove any airbox cover screws if equipped.
• Release the airbox clips by hand or with the flat-blade trim tool if they are tight.
• Keep the intake opening covered.

Step 2: Lift out the old filter

• Lift the airbox lid carefully and set it aside.
• Pull the old filter straight out by hand.
• Check that no leaves, dust, or loose debris fall into the lower airbox.

Step 3: Clean the airbox

• Use your hand to wipe out loose dirt from the airbox.
• Do not let debris fall into the intake tube.
• Make sure the old filter seal did not stick to the housing.

Step 4: Install the new filter

• Place the new engine air filter into the airbox in the same direction as the old one.
• Press it down evenly so the seal sits flat all the way around.
• A crooked filter can let dirt past the seal.

Step 5: Reinstall the airbox lid

• Set the airbox lid back in place and make sure it seats correctly.
• Reinstall the clips by hand.
• If screws were removed, use the Torx T25 screwdriver to reinstall them.
• Tighten snugly only; there is no high torque spec for this cover.
