• ⚠️ Don’t touch the MAF sensor (mass airflow sensor). It’s a delicate airflow sensor in the intake tube.
• ⚠️ Don’t drop dirt or leaves into the air box or intake tube.

🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Locate the air filter housing

• Open the hood and look for the large black plastic air box on the passenger side of the engine bay.
• The air box connects to a large intake tube that runs toward the engine.

Step 2: Unlatch the air box cover

• Use your hands to flip open the metal retaining clips on the air box lid.
• If a clip is stubborn, use a flathead screwdriver gently to help pry the clip open. Don’t force it—clips can snap.

Step 3: Open the air box and remove the old filter

• Lift the air box lid just enough to access the filter.
• Pull the old air filter straight out with your hands.
• Use a shop towel to cover the opening if you need a moment—this helps prevent debris falling in.

Step 4: Clean out the air box (lightly)

• Use a small vacuum to remove loose leaves, sand, or dirt from the bottom of the air box.
• Wipe the sealing surfaces (where the filter’s rubber edge sits) with a shop towel.
• Do not vacuum or touch any sensor in the intake tube.

Step 5: Install the new air filter

• Place the new filter into the air box in the same direction as the old one.
• Make sure it sits flat and the rubber seal is fully seated all the way around. A crooked filter can leak unfiltered air.

Step 6: Close the air box and secure it

• Lower the air box lid back into place.
• Re-close all retaining clips by hand until they snap fully shut.
• Do a quick visual check that the lid is evenly closed on all sides.

✅ After Repair

• Start the engine and let it idle for 10–20 seconds. It should run smoothly.
• Listen for whistling or hissing near the air box—this can mean the lid isn’t sealed.
• Re-check that all clips are fully latched and nothing was left in the engine bay.
