• Open the hood and locate the air cleaner box on the passenger-side front of the engine bay (the large black plastic box connected to the intake tube).

🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Locate the air cleaner box

• Use a small flashlight to identify the air cleaner box lid and the clips or screws that hold it closed.

Step 2: Release the air cleaner box lid

• If your lid uses metal clips, pop them open using a flathead screwdriver (a flat-tip tool that pries clips open).
• If your lid uses screws, loosen them with an 8mm socket and 1/4" ratchet.
• Lift the lid up enough to remove the filter. Don’t yank on the intake tube.

Step 3: Remove the old air filter

• Pull the filter straight up and out by hand while wearing nitrile gloves.
• Use a clean shop towel to wipe loose dirt out of the air box only (do not push dirt into the intake opening).

Step 4: Install the new air filter

• Place the new filter into the lower air box by hand, matching the shape so it sits flat all the way around.
• Check the filter’s rubber edge is fully seated with no gaps. Uneven seating can trigger a whistling noise.

Step 5: Close and secure the air cleaner box

• Lower the lid back into place by hand.
• Re-latch the clips by hand, or snug the screws with an 8mm socket and 1/4" ratchet (do not overtighten—plastic can crack).

✅ After Repair

• Start the engine and let it idle for 20-30 seconds.
• Listen for air leaks (hissing/whistling). If you hear one, shut off the engine and re-seat the filter and lid.
• Take a short drive and confirm normal throttle response.
