🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Locate and open the air box

• Use a flashlight to find the air box lid seam and the retaining fasteners.
• If your air box uses metal latches, pop them open using a flathead screwdriver if needed.
• If your air box uses small bolts/screws instead, loosen them using an 8mm socket and 1/4" drive ratchet.
• Don’t remove more parts than necessary.

Step 2: Lift the air box lid

• Lift the lid straight up by hand; you usually only need to open it enough to slide the filter out.
• If the lid feels stuck, re-check for a missed latch/8mm fastener using the flashlight.
• Avoid pulling hard on the intake tube. (The intake tube is the large plastic/rubber tube feeding the engine.)

Step 3: Remove the old air filter

• Slide the filter out by hand.
• Use the flashlight to look into the lower air box for leaves/sand.

Step 4: Clean the air box sealing surface

• Use a clean microfiber towel to wipe the inside edge where the filter seals.
• Do not let debris fall down the intake opening.

Step 5: Install the new air filter

• Place the new filter into the lower air box by hand.
• Make sure it sits flat and fully seated all the way around.
• Use the flashlight to confirm the filter gasket edge isn’t folded over.

Step 6: Close and secure the air box

• Close the air box lid and align it evenly with the lower half.
• Re-latch the clips by hand (use a flathead screwdriver only if necessary).
• If equipped with fasteners, snug them using an 8mm socket and 1/4" drive ratchet.

✅ After Repair

• Start the engine and let it idle for 10–20 seconds.
• Listen for any whistling/hissing (can mean the air box lid isn’t fully sealed).
• Re-check the latches/8mm fasteners if you hear an air leak sound.
