🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Open the hood and locate the air filter housing

• Open the hood and support it securely.
• Use a flashlight to find the black plastic air filter box (air cleaner housing) connected to the intake tube.

Step 2: Release the airbox cover (clips or screws)

• If your airbox uses metal latches, flip them open by hand or with a flat trim tool (a non-scratch prying tool).
• If your airbox uses screws, remove them using a Torx T25 screwdriver or Phillips #2 screwdriver (varies by housing style).
• If an intake snorkel or small bracket blocks access, loosen the fastener using a 10mm socket, 1/4" ratchet, and 6" extension.

Step 3: Lift the airbox cover and remove the old filter

• Lift the airbox lid straight up just enough to access the filter (you usually don’t need to fully remove the lid).
• Pull the old air filter out.
• Use the flashlight to check the bottom of the airbox for leaves/sand and wipe it clean with a dry rag (do not let debris fall into the intake).

Step 4: Install the new air filter (correct orientation)

• Insert the new filter into the airbox the same way the old one came out.
• Make sure the filter’s rubber edge sits flat all the way around (no waves or corners folded).
• A pinched seal can trigger a rough idle.

Step 5: Reinstall and secure the airbox cover

• Lower the airbox lid carefully, making sure it seats evenly.
• Re-close the metal clips, or reinstall the screws using a Torx T25 screwdriver / Phillips #2 screwdriver.
• If screws are used: Torque to 5 Nm (44 in-lbs).
• Re-tighten any loosened bracket/snorkel fasteners using a 10mm socket and 1/4" ratchet (snug, do not over-tighten plastic).

Step 6: Final under-hood check

• Confirm no tools are left in the engine bay.
• Visually confirm the intake tube is fully seated and nothing is cracked or disconnected.

✅ After Repair

• Start the engine and let it idle for 30–60 seconds.
• Listen for a whistling/hissing sound (can indicate the airbox isn’t sealed).
• Take a short test drive and confirm normal throttle response and no warning lights.
