• Open the hood and let the engine cool for at least 15–20 minutes.

🔨 Step-by-Step Instructions

Follow these steps in order:

Assumption: Your GLE uses the standard single-panel filter in the main air box (most 3.5L V6 setups). If your air box cover has multiple Torx screws, follow the “screws” steps; if it has metal clips, follow the “clips” steps.

Step 1: Locate the air box

• Use a flashlight and find the large black plastic air box near the front of the engine bay with an intake duct (air tube) attached.

Step 2: Loosen the air box cover (clips OR screws)

• If your air box has metal clips: pop them open using a small flathead screwdriver.
• If your air box has screws: remove them using a Torx T25 driver (some versions may also use an 8mm socket with a 1/4" ratchet).
• Keep screws in a pocket or tray.

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

• Lift the air box lid upward carefully by hand (don’t yank on the intake duct).
• Pull the old filter straight out.
• Use clean shop towels to wipe the inside of the air box only if it’s dusty. Do not push dirt into the intake opening.

Step 4: Install the new filter correctly

• Place the new air filter into the air box the same way the old one came out.
• Make sure the filter’s rubber edge seats evenly all the way around (no waves or gaps). A poor seal lets dirt bypass the filter.

Step 5: Re-close and secure the air box

• Lower the air box lid and confirm it sits flush all the way around.
• Reinstall screws using a Torx T25 driver (or 8mm socket + 1/4" ratchet if equipped) and snug them evenly.
• Torque to 3–4 Nm (27–35 in-lbs) if you have a small torque wrench; otherwise tighten gently—these are plastic threads.
• Re-latch the clips by hand if your air box uses clips.

Step 6: Final visual check

• Use a flashlight to confirm: lid fully seated, all clips latched or screws installed, and no tools/towels left in the engine bay.

✅ After Repair

• Start the engine and let it idle for 20–30 seconds.
• Listen for any loud hissing/whistling (can mean the air box lid isn’t sealed).
• Take a short drive and confirm there’s no check-engine light.
