🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Locate the air filter box

• Use a flashlight to find the large black plastic air box connected to the intake tube (the big plastic/rubber tube going toward the engine).
• You’ll see metal clips and/or hose clamps holding the air box lid on.

Step 2: Release the air box lid

• Unclip the metal latches by hand (wear work gloves if they’re tight).
• If your air box uses a clamp, loosen it using a 7mm socket with a 1/4" drive ratchet (or use a flathead screwdriver (medium) if it’s a screw-type clamp).
• Tip: Don’t remove the clamp—just loosen it.

Step 3: Open the air box and remove the old filter

• Lift the air box lid up enough to access the filter. You usually don’t need to fully remove the lid.
• Pull the old filter straight out.
• Use safety glasses and visually check the bottom half of the air box for leaves/dirt.

Step 4: Clean out the air box (lightly)

• Use the flashlight and wipe out loose debris with a clean rag (do not drop anything into the intake opening).
• Tip: Do not use water inside the air box.

Step 5: Install the new air filter

• Slide the new engine air filter into the air box the same direction as the old one.
• Make sure it sits flat and the rubber edge seals all the way around.
• Tip: If it won’t sit flat, it’s not aligned.

Step 6: Close and secure the air box

• Lower the lid back into place and ensure it’s seated evenly.
• Re-latch the clips by hand.
• If you loosened a clamp, tighten it using the 7mm socket and 1/4" drive ratchet (snug, not over-tight).

Step 7: Final check

• Use the flashlight to confirm: no gaps around the air box lid, and all clips/clamps are secure.
• Make sure you didn’t leave any tools in the engine bay.

✅ After Repair

• Start the engine and let it idle for 20-30 seconds.
• Listen for a hissing/whistling sound (that can mean the air box lid or clamp isn’t sealed).
• If the engine sounds normal, close the hood and you’re done.
