🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Open the hood and locate the air box

• Release the hood latch, then secure the hood.
• Find the black plastic air box near the front of the engine bay on the passenger side.
• Tip: The air box usually has clips or screws on the lid.

Step 2: Release the air box cover

• Use a flat trim tool or by hand to release the retaining clips on the air box lid.
• If your air box uses screws, remove them with the correct screwdriver or socket.
• Lift the lid carefully so nothing falls into the intake tube.

Step 3: Remove the old air filter

• Lift the old filter straight out of the air box.
• Check the air box for leaves, dust, or debris and wipe it clean with a dry cloth if needed.
• Tip: Do not use compressed air inside the engine intake.

Step 4: Install the new air filter

• Place the new engine air filter into the air box in the same orientation as the old one.
• Make sure the filter sits flat all the way around the sealing edge.

Step 5: Reinstall the air box cover

• Set the lid back on the air box and align it correctly.
• Use your hands to snap the clips back into place or reinstall any screws you removed.
• Make sure the lid is fully sealed so unfiltered air cannot enter the engine.

Step 6: Final check

• Close the hood.
• Start the engine and listen for any unusual air leaks or whistling sounds.
• If the engine runs normally, the job is complete.
