🔨 Step-by-Step Instructions

Follow these steps in order:

Assumption: Your Tucson uses a standard rectangular “panel” air filter inside the engine airbox (common on the 1.6T).

Step 1: Open the hood and locate the airbox

• Open the hood and secure it with the hood prop (if equipped).
• Find the engine airbox (the plastic box connected to the intake tube going toward the turbo).

Step 2: Unclip or unbolt the airbox lid

• If your airbox uses metal clips, release them by hand (flip them open).
• If your airbox uses screws/bolts, use a Phillips screwdriver #2 or 8mm socket with a 1/4" ratchet to loosen them.
• Avoid pulling hard on any hoses or wiring attached to the lid.

Step 3: Lift the lid and remove the old air filter

• Lift the airbox lid just enough to access the filter (you usually don’t need to fully remove the lid).
• Pull the old filter straight out.
• Use a shop towel to wipe out loose dust inside the lower airbox.
• Tip: Don’t drop debris into the intake opening.

Step 4: Install the new air filter correctly

• Insert the new filter into the airbox the same way the old one came out.
• Make sure the rubber seal sits flat all the way around (no corners folded).
• If the filter has an airflow arrow, point it toward the engine (toward the intake tube).

Step 5: Reinstall and secure the airbox lid

• Lower the lid carefully, making sure it sits evenly on the airbox.
• Refasten the clips by hand, or tighten fasteners using the Phillips screwdriver #2 or 8mm socket with 1/4" ratchet.
• Do not overtighten screws/bolts—snug is enough for plastic housings.

Step 6: Quick visual check

• Confirm nothing is pinched between the lid and box.
• Confirm the intake tube connection looks undisturbed and seated.

✅ After Repair

• Start the engine and let it idle for 15–30 seconds.
• Listen for any loud hissing/whistling that could indicate the airbox lid isn’t sealed.
• If you hear a leak, shut the engine off and re-check the filter seating and lid clips/screws.
