🔨 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 filter box near the front of the engine bay, connected to the intake tube.

Step 2: Release the airbox cover

• Release the metal clips around the airbox cover by hand.
• If your airbox uses screws instead of clips, loosen them with an 8mm socket and 1/4" drive ratchet.
• If an intake hose clamp blocks the cover, loosen it with a flat-blade screwdriver (a clamp is the band that tightens around the rubber tube).

Step 3: Open the airbox and remove the old filter

• Lift the airbox cover just enough to slide the filter out.
• Pull the old filter straight out by hand and keep it angled so debris doesn’t fall into the lower box.
• Tip: Note which side faces up.

Step 4: Clean the airbox sealing surfaces

• Wipe the lower airbox and the sealing edge with a clean rag (no wet cleaners needed).
• Do not let dirt drop into the intake opening.

Step 5: Install the new air filter

• Place the new filter into the lower airbox, making sure it sits flat and fully in the groove.
• Confirm the rubber edge (gasket) is evenly seated all the way around.

Step 6: Re-close and secure the airbox

• Lower the airbox cover and make sure it lines up without pinching the filter.
• Snap the clips back into place by hand.
• If you loosened any screws or clamps, snug them using an 8mm socket or flat-blade screwdriver.
• Tip: A crooked cover can trigger a check engine light.

✅ After Repair

• Start the engine and let it idle for 20–30 seconds.
• Listen for whistling or hissing near the airbox (that can mean an air leak).
• If a check engine light appears, re-check that the airbox cover is fully seated and all clamps are snug.
