🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Locate the air box

• Use a flashlight to find the large black plastic air box connected to the intake tube.
• Wipe loose dirt off the outside with a clean rag so it won’t drop inside when opened.

Step 2: Release the air box cover

• If your air box uses metal clips, unhook them by hand or with a flathead screwdriver.
• If your air box uses screws, loosen them with an 8mm nut driver (do not remove more than needed).
• Don’t pry hard; plastic tabs can snap.

Step 3: Open the air box

• Lift the air box lid straight up enough to access the filter.
• Do not pull hard on the intake tube; just open the lid as far as it comfortably goes.

Step 4: Remove the old air filter

• Lift the filter out and note how it sits in the box (which side faces up).
• Use a flashlight to check for leaves or dirt in the bottom of the air box.

Step 5: Clean the air box sealing surface

• Use a clean rag (no soaking chemicals) to wipe the sealing edge where the filter sits.
• Do not let debris fall into the intake opening.

Step 6: Install the new air filter

• Set the new filter into the air box the same way the old one came out.
• Make sure it sits flat all the way around (no corners folded).

Step 7: Close and secure the air box

• Lower the lid and confirm it seats evenly on the air box.
• Re-latch the metal clips by hand, or snug the screws with an 8mm nut driver (do not overtighten).

✅ After Repair

• Do a quick visual check that all clips/screws are secured and the intake tube isn’t loose.
• If you have a check engine light afterward, re-check that the air box lid is fully seated.
