🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Locate the air filter box

• Use a small flashlight to find the black plastic air filter box near the front/side of the engine bay, with a large intake tube attached.

Step 2: Open the air filter box

• If your air box uses metal latches, pop them open using a flat-blade screwdriver if needed. Most open by hand.
• If your air box uses screws/bolts, loosen them with an 8mm socket and 1/4" drive ratchet until the lid can lift.
• Don’t force it—look for one more latch/screw.

Step 3: Lift the lid and remove the old filter

• Lift the air box lid by hand (you usually don’t need to remove the intake tube).
• Pull the old filter straight up/out by hand.
• Use a shop towel to wipe dirt from the inside of the air box. Do not let dirt fall into the intake.

Step 4: Install the new air filter

• Place the new filter into the air box by hand.
• Make sure it sits flat and the rubber edge (seal) is fully seated all the way around. This seal is what keeps unfiltered air out.

Step 5: Close and secure the air filter box

• Lower the lid back into place by hand, making sure it lines up evenly.
• Re-latch the metal clips by hand (or with a flat-blade screwdriver if tight).
• If equipped with screws/bolts, snug them with an 8mm socket and 1/4" drive ratchet. Just snug—plastic strips easily.

✅ After Repair

• Start the engine and listen for any hissing/whistling that could indicate the air box lid isn’t sealed.
• Re-check the latches/screws and that the lid sits evenly all the way around.
• Write the date/mileage on the filter (use a pen) to track when you changed it.
