🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Locate the airbox

• Find the black plastic air filter box in the engine bay with a large intake tube connected to it.
• Put on safety glasses and work gloves.

Step 2: Loosen the intake tube clamp (if it limits lid movement)

• Use a 7mm socket with a 1/4" drive ratchet to loosen the worm-gear clamp at the airbox outlet.
• A worm-gear clamp is the common band clamp tightened by a small screw.
• Torque to 3 Nm (27 in-lbs) when tightening during reassembly.

Step 3: Release the airbox lid clips

• Unclip the metal retaining clips around the airbox lid by hand.
• If a clip is stubborn, gently pry it with a flat-blade screwdriver (don’t snap the clip).

Step 4: Open the airbox and remove the old filter

• Lift the airbox lid up enough to access the filter (you may not need to fully remove the lid).
• Pull the old air filter straight out.
• Note how the filter sits before removing.

Step 5: Clean the airbox sealing surface

• Use a flat-blade screwdriver (very gently) or your gloved hand to remove any leaves/debris from the airbox.
• Do not push dirt into the intake opening.

Step 6: Install the new air filter

• Place the new filter into the lower airbox the same way the old one came out.
• Make sure it sits flat and the rubber edge (seal) is fully seated all the way around.
• A pinched seal can cause unfiltered air leaks.

Step 7: Close the airbox and secure everything

• Lower the airbox lid into position.
• Snap all the metal clips back on by hand.
• Re-tighten the intake tube clamp using the 7mm socket and 1/4" drive ratchet to Torque to 3 Nm (27 in-lbs).

✅ After Repair

• Listen for a hissing/whistling sound near the airbox (can indicate a loose clamp or lid not seated).
• Quickly re-check that all clips are latched and the intake tube clamp is snug.
