🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Locate the air filter housing

• Use a flashlight to find the black plastic airbox connected to the large intake tube.
• Wipe off loose dust around the airbox seam using a shop towel so dirt doesn’t fall inside.

Step 2: Open the airbox

• Release the metal clips around the airbox by hand. If one is stubborn, gently help it with a flathead screwdriver.
• Lift the airbox lid upward. Don’t yank the intake tube.

Step 3: Remove the old air filter

• Pull the filter straight up and out by hand.
• Use the flashlight to check the bottom of the airbox for leaves/sand.

Step 4: Clean the airbox sealing surface

• Wipe the inside edges (where the filter seals) using a shop towel.
• If debris is sitting in the bottom, carefully lift it out with the shop towel (avoid pushing dirt 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 down in its pocket.
• Make sure the rubber seal is evenly seated all the way around. A crooked seal lets dirt in.

Step 6: Close and secure the airbox

• Lower the lid straight down so it matches the bottom half evenly.
• Snap all airbox clips back into place by hand.
• Do a quick visual check around the seam: it should look even with no gaps.

✅ After Repair

• Start the engine and let it idle for 20–30 seconds.
• Listen for a hissing/whistling sound near the airbox (can indicate the lid isn’t sealed).
• If you hear a leak, shut it off and re-check that the filter is seated and the clips are fully latched.
