📋 Before You Begin

• Park on level ground, shift to Park, and set the parking brake.
• Open the hood and locate the air filter box (large black plastic box on the engine bay with an intake tube attached).
• If there’s dust/leaves around the box, wipe it away with a shop towel so debris doesn’t fall inside.

🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Locate and inspect the air filter box

• Use a flashlight to find the air filter box seam and the fasteners (metal clips and/or small bolts).
• Take a quick photo before opening.

Step 2: Open the air filter box

• If your box uses clips: pry and release them using a flathead screwdriver.
• If your box uses bolts/screws: loosen/remove them using an 8mm socket and 1/4" ratchet.
• Lift the top half of the box straight up enough to remove the filter. Don’t force it against the intake tube.

Step 3: Remove the old filter

• Pull the filter straight out by hand (use nitrile gloves if it’s dusty).
• Use a flashlight to confirm which way the filter sits (rubber sealing edge should match the box’s sealing surface).

Step 4: Clean the air box sealing area

• Wipe the inside edge (the sealing lip) with a shop towel.
• Do not let dirt fall into the intake opening. If you see loose debris, wipe it out carefully.

Step 5: Install the new filter

• Place the new filter into the lower half of the box by hand, making sure it sits fully flat.
• Confirm the rubber seal is evenly seated all the way around (no corners folded).

Step 6: Close and secure the air filter box

• Lower the top half of the box back into place by hand, keeping the filter from shifting.
• Re-latch the clips by hand (use a flathead screwdriver only if needed to help seat them).
• If you removed bolts/screws, reinstall and snug them using an 8mm socket and 1/4" ratchet. Snug only—don’t overtighten plastic.

Step 7: Final check

• Do a quick perimeter check with a flashlight: the box seam should be even with no gaps.
• Make sure no tools or towels are left in the engine bay.

✅ After Repair

• Start the engine and let it idle for 20–30 seconds. Listen for hissing/whistling that could indicate the air box isn’t sealed.
