🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Locate the air filter box

• Use a flashlight to find the black plastic air box near the front/side of the engine bay.
• The engine air filter sits inside this box under a lid.

Step 2: Release the air box lid fasteners

• If your air box uses screws: use a Torx T25 driver to loosen/remove the lid screws.
• If your air box uses clips: use a flathead screwdriver to gently pry the clips open.
• Don’t force it—clips snap if twisted.

Step 3: Lift the lid and remove the old filter

• Lift the air box lid up just enough to access the filter (you usually don’t need to remove the whole lid).
• Pull the old filter straight out by hand.
• Use a shop towel to cover the opening if you need to pause.

Step 4: Clean the air box sealing surface

• Use a shop towel to wipe out loose dust from the lower air box.
• Do not push dirt deeper into the intake tract.

Step 5: Install the new filter (correct direction)

• Place the new filter into the lower air box by hand.
• Make sure it sits flat and fully into the corners (the rubber edge should seal all the way around).
• If it won’t sit flat, it’s not aligned yet.

Step 6: Reinstall and secure the air box lid

• Lower the lid carefully so it doesn’t pinch or fold the filter.
• If equipped with screws: use a Torx T25 driver to tighten the screws snugly (do not overtighten into plastic).
• If equipped with clips: press the clips closed by hand; use a flathead screwdriver only if needed to help seat them.

✅ After Repair

• Start the engine and let it idle for 15–30 seconds.
• Listen for whistling/hissing that could indicate the air box lid isn’t fully sealed.
• Do a quick visual check that all screws/clips are fully secured.
