🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Open the hood and locate the air filter box

• Open the hood and support it securely.
• Use a flashlight to find the black plastic airbox on the engine bay (the box connected to the large intake tube).

Step 2: Release the airbox lid clips

• Put on nitrile gloves and safety glasses.
• Release the metal retaining clips holding the airbox lid down.
• If a clip is stubborn, gently help it with a flathead screwdriver (small) (don’t pry hard). Clips should pop free, not bend.

Step 3: Open the airbox and remove the old filter

• Lift the airbox lid enough to access the filter (you usually don’t need to remove the whole lid).
• Pull the old filter straight out.
• Use a shop towel to wipe loose dirt from the airbox sealing surface (don’t push debris into the intake).

Step 4: Install the new filter correctly

• Slide the new filter into the airbox the same way the old one came out.
• Make sure the filter sits flat and fully seated in the lower half of the airbox (no corners folded).
• Check the rubber edge is evenly seated all the way around. A pinched seal can cause unfiltered air.

Step 5: Close the airbox and secure the clips

• Lower the lid and align it with the lower airbox.
• Snap each retaining clip back into place by hand.
• Do a quick visual check that the lid is fully closed on all sides.

✅ After Repair

• 👀 Start the engine and let it idle for 10–20 seconds; listen for any hissing/whistling that could indicate the airbox isn’t sealed.
• 🧼 Recheck the clips and lid alignment if anything sounds “leaky.”
• 🗓️ Note the mileage/date so you know when it was last replaced.
