🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Locate the air box

• Open the hood.
• Use a flashlight to find the black plastic air box on the passenger-side area of the engine bay, connected to a large intake tube.

Step 2: Release the air box clips

• Find the metal retaining clips that hold the air box lid to the lower half.
• Flip each clip open by hand; if one is stubborn, gently help it with a flat-blade screwdriver (medium).
• Tip: Don’t pry hard—clips can bend.

Step 3: Open the air box lid

• Lift the air box lid enough to access the filter.
• If the intake tube limits movement, lift the lid slowly and don’t force it.

Step 4: Remove the old filter

• Pull the old filter straight out.
• Use a flashlight to look inside the lower air box for leaves or heavy dirt.
• Wipe the sealing edge with a clean shop towel.

Step 5: Install the new filter (correct direction)

• Slide the new filter into the air box the same way the old one came out.
• Make sure the filter sits flat and fully down in the tray with no corners folded.
• Tip: A crooked filter can let dust bypass.

Step 6: Close the air box and latch the clips

• Lower the air box lid so it mates evenly all the way around.
• Snap all retaining clips closed by hand.
• Do a quick “tug test” on the lid to confirm it’s secure.

✅ After Repair

• 🧼 Recheck that all clips are fully latched and the lid seam is even.
• 📅 Consider writing the date/mileage on the filter frame with a marker for next time.
