🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Locate the air filter housing

• Use a flashlight to find the black plastic air box on the passenger-side front area of the engine bay.
• The air filter sits inside this box, right before the intake tube that goes to the engine.

Step 2: Unclip the air box cover

• Use your fingers to flip open the metal retaining clips on the air box.
• If a clip is stubborn, gently assist it with a small flat-blade screwdriver (do not pry hard—plastic can crack). Gentle pressure is all you need.

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

• Lift the air box lid upward (you usually don’t need to remove any hoses).
• Pull the old air filter straight out with nitrile gloves.
• Use a flashlight to check the inside of the lower air box for leaves or dirt.

Step 4: Install the new air filter

• Slide in the new engine air filter in the same direction as the old one.
• Make sure it sits fully down in the air box and the edges are evenly seated all the way around (no gaps).

Step 5: Close and secure the air box

• Lower the lid back into place, making sure the lid aligns with the bottom half of the air box.
• Snap the retaining clips back on by hand; use the small flat-blade screwdriver only if needed to guide a clip into place.

Step 6: Final check

• Use the flashlight to confirm all clips are fully latched and the air box lid sits flat.
• Make sure you didn’t leave any tools or rags in the engine bay.

✅ After Repair

• Listen for any hissing/whistling that could indicate the air box isn’t sealed.
• If you hear a leak, shut the engine off and re-check that the filter is seated and the clips are fully latched.
