🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Locate the air box

• Use a flashlight to find the black plastic air box in the engine bay (it’s the box connected to the large intake tube).

Step 2: Unclip the air box cover

• Release the metal retaining clips around the air box by hand.
• If a clip is tight, gently pry it with a flathead screwdriver. Don’t force it—clips can bend.

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

• Lift the air box lid straight up (you usually don’t need to remove any hoses).
• Pull the old filter straight out using nitrile gloves.

Step 4: Clean the air box sealing area

• Use the flashlight to look inside the lower air box for leaves or heavy dirt.
• Wipe the air box rim (where the filter seals) with a clean rag you have available. A clean seal prevents unfiltered air leaks.

Step 5: Install the new engine air filter

• Place the new filter into the lower air box in the same orientation as the old one.
• Make sure it sits flat all the way around (no corners folded).

Step 6: Close and secure the air box

• Lower the lid carefully, keeping the filter aligned.
• Snap all the clips back into place by hand.
• Do a quick visual check with the flashlight to confirm the lid is fully seated and even.

✅ After Repair

• Listen for unusual hissing/whistling that could indicate the air box isn’t sealed.
• If you see a check engine light afterward, re-check that the air box lid is fully clipped and seated evenly.
