🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Locate the air filter housing (airbox)

• Open the hood and look for a black plastic box on the driver-side area of the engine bay, connected to the intake tube.
• Use a flashlight to spot the metal retaining clips around the airbox lid.

Step 2: Unclip the airbox lid

• Use nitrile gloves and release the metal clips by pulling them outward and down until they pop free.
• Tip: Support the lid so it doesn’t snap back.

Step 3: Open the airbox and remove the old filter

• Lift the airbox lid up just enough to access the filter (you usually don’t need to remove the whole lid).
• Pull the old filter straight out.
• Use a flashlight to check the airbox for leaves or heavy dirt. If needed, wipe it with a clean rag (don’t let debris fall into the intake tube).

Step 4: Install the new air filter (correct orientation)

• Insert the new filter into the airbox the same way the old one came out.
• Make sure the filter sits flat in its groove all the way around so the lid seals properly.
• Tip: If the lid won’t close, the filter isn’t seated.

Step 5: Close the airbox and re-clip it

• Press the lid down evenly, keeping it aligned with the lower half of the airbox.
• Snap each clip back into place by pushing it up and inward until it locks.
• Use a flashlight to confirm the lid is fully seated on all sides.

✅ After Repair
