🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Locate the air filter housing

• Open the hood and use a flashlight to find the black plastic air box (air filter housing) connected to the large intake tube.
• It’s usually on the driver-side front area.

Step 2: Release the air box fasteners

• Release the metal clips around the air box by hand.
• If your air box uses screws instead of clips, loosen them using a Phillips screwdriver (do not remove them unless necessary).
• If a clip is stubborn, gently help it with a flat-blade screwdriver (a flat tip used to pry carefully).

Step 3: Open the air box

• Lift the air box lid just enough to remove the filter.
• Use a shop towel to wipe loose dirt from the inside of the air box.
• Do not let dirt fall down into the intake tube opening.

Step 4: Remove the old filter

• Pull the old filter straight out by hand.
• Use a flashlight to check the bottom of the air box for leaves or debris and remove it by hand or with a shop towel.

Step 5: Install the new filter

• Place the new filter into the lower half of the air box, seated evenly all the way around.
• Make sure the rubber edge (gasket) sits flat; no corners should be folded.
• If it doesn’t sit flat, it’s not sealed.

Step 6: Close and secure the air box

• Close the air box lid fully.
• Re-latch all clips by hand, or snug screws with a Phillips screwdriver (tighten until snug; do not overtighten plastic).
• Visually confirm the lid seam is even all the way around.

✅ After Repair

• Start the engine and let it idle for 10-20 seconds.
• Listen for any loud hissing/whistling, which can mean the air box isn’t fully closed.
• Do a quick re-check that all clips/screws are secured.
