🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Locate the air box and fasteners

• Use a flashlight to find the air box seams and the metal clips and/or screws holding the lid on.
• The air box is the plastic “filter container.”

Step 2: Loosen the intake clamp (if it blocks the lid)

• If the lid cannot lift due to the intake tube, loosen the clamp using an 8mm socket with a 1/4" drive ratchet (or a flathead screwdriver (medium) if it’s a screw-style clamp).
• Loosen only enough to let the tube flex—do not fully remove the clamp.

Step 3: Unfasten the air box lid

• Release the metal clips by hand (wear work gloves), or remove any lid screws using the 8mm socket and 1/4" drive ratchet.
• Lift the air box lid upward. If it’s tight, gently wiggle it—do not force it.

Step 4: Remove the old air filter

• Pull the filter straight out by hand.
• Use the flashlight to note how it sits (which side faces up and how the edges seal).

Step 5: Clean the air box (lightly)

• Use a clean shop towel to wipe out loose dust inside the lower air box.
• Do not let dirt fall down the intake opening.

Step 6: Install the new air filter

• Place the new filter into the lower air box by hand.
• Make sure the rubber edge sits flat all the way around (this is the “seal” that keeps dirt out).
• If it rocks or won’t sit flat, it’s misaligned.

Step 7: Close and secure the air box

• Lower the lid back into place by hand, ensuring it seats evenly on the air box.
• Re-latch the clips by hand or reinstall screws using the 8mm socket and 1/4" drive ratchet (snug, do not over-tighten).

Step 8: Re-tighten the intake clamp (if loosened)

• Tighten the clamp using the 8mm socket and 1/4" drive ratchet (or flathead screwdriver (medium)).
• Make sure the tube is fully seated and the clamp is snug so there are no air leaks.

✅ After Repair

• Start the engine and let it idle for 10–20 seconds.
• Listen for a hissing sound (could indicate a loose clamp or lid not seated).
• Do a quick visual check that all clips/screws are secured and no tools are left in the engine bay.
