🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Locate the air filter housing

• Use a flashlight to find the black plastic air box in the engine bay (it connects to a large air intake tube).

Step 2: Unclip the air box lid

• Use a flathead screwdriver (medium) to help lift the metal retaining clips (if they’re tight), then unclip them by hand.
• Don’t pry hard—clips can bend.

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

• Lift the lid enough to access the filter (you usually don’t need to fully remove the lid).
• Pull the old filter straight out by hand and keep it upright so debris doesn’t fall.
• Use a shop towel to wipe out loose dirt in the lower air box.

Step 4: Install the new filter

• Place the new filter into the air box by hand, making sure it sits flat in the tray.
• Confirm the rubber edge (gasket) is fully seated all the way around.

Step 5: Close the air box and re-secure the clips

• Lower the air box lid into position by hand.
• Snap each clip closed by hand; use the flathead screwdriver (medium) only if you need gentle help pushing a clip over.
• Do a quick tug test on the lid—there should be no gap.

✅ After Repair

• 👂 Start the engine and listen for any loud hissing/whistling that could indicate the air box lid isn’t sealed.
• Visually re-check that all clips are fully latched and the intake tube wasn’t knocked loose.
• If a check engine light appears afterward, re-check that everything is sealed and no sensor connector was disturbed.
