🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Locate the air filter box (airbox)

• Use a flashlight to find the black plastic box connected to a large intake tube (the tube that carries air to the engine).
• The airbox is in the engine bay and will have metal clips and/or screws holding the lid on.

Step 2: Unlatch the airbox lid

• Use a flathead screwdriver 5mm to gently flip open the metal retaining clips (if equipped).
• If your airbox has screws instead of clips, use a Phillips screwdriver #2 to loosen/remove them.
• Don’t force it—clips pop with light pressure.

Step 3: Open the airbox and remove the old filter

• Lift the airbox lid up just enough to access the filter (you usually don’t need to fully remove the lid).
• Pull the old air filter straight out.
• Use a shop towel to wipe loose dust from the inside of the airbox.
• Do not drop dirt into the intake opening.

Step 4: Install the new air filter correctly

• Compare the new filter to the old one to confirm it’s the same shape and size.
• Place the new filter into the airbox the same way the old one came out.
• Make sure the filter sits flat all the way around (no corners folded or pinched).

Step 5: Close and secure the airbox lid

• Lower the lid and check that it lines up evenly with the bottom half of the airbox.
• Re-lock the clips by hand; if needed, use a flathead screwdriver 5mm to help seat them.
• If screws were removed, reinstall and snug them using a Phillips screwdriver #2.

Step 6: Quick final check

• Use a flashlight to confirm the airbox lid is fully closed on all sides.
• Make sure no tools or towels are left in the engine bay.

✅ After Repair

• Start the engine and let it idle for 10–20 seconds.
• Listen for any loud hissing/whistling that could indicate the airbox lid isn’t sealed.
• If you hear a leak, shut the engine off and re-check that the filter is seated and the clips/screws are fully secured.
