🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Open the air filter housing

• Use a flashlight to find the air box lid and its clips or screws.
• If your air box uses metal clips, release them by hand; if they’re tight, gently pry with a flathead screwdriver.
• If your air box uses bolts, remove them with a 10mm socket and 1/4" drive ratchet.
• Don’t force the lid; check for hidden fasteners.

Step 2: Remove the old air filter

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

Step 3: Install the new air filter

• Place the new engine air filter into the lower half of the air box.
• Make sure the filter’s rubber edge (gasket) sits flat all the way around; no corners should be folded.
• Align the filter the same way the old one came out (some have a specific top/bottom orientation).

Step 4: Close and secure the air filter housing

• Lower the air box lid into place.
• Re-latch the clips by hand, or reinstall the bolts using a 10mm socket and 1/4" drive ratchet.
• Snug the bolts (do not over-tighten plastic). Torque to 5 Nm (44 in-lbs) if you have a torque wrench.

Step 5: Quick final check

• Confirm the lid is fully seated and all clips/bolts are secured.
• Make sure no tools or towels are left in the engine bay.

✅ After Repair

• Start the engine and let it idle for 30 seconds.
• Listen for any whistling or hissing (can mean the air box lid isn’t sealed).
• If you hear a leak, shut it off and re-check the filter seating and latches.
