📋 Before You Begin

• 🅿️ Park your Tucson on level ground and set the parking brake.
• 🧊 Open the hood and let the engine cool for a few minutes.
• 💡 The air filter box is a black plastic box near the front-left side of the engine bay when standing in front of the vehicle.
• 💡 A retaining clip is a small metal latch that holds the air filter box lid closed.

🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Open the Hood

• Use your hand to pull the hood release handle inside the cabin, low on the driver-side lower dash area.
• Go to the front of your Tucson and use your fingers to move the secondary hood latch under the front edge of the hood.
• Lift the hood fully and make sure it is safely supported.
• Put on safety glasses and nitrile gloves.

Step 2: Locate the Engine Air Filter Box

• Use your eyes to locate the black plastic air filter box in the engine bay.
• It connects to a large black intake tube that leads toward the engine.
• Do not remove the intake tube for this job.
• Look for metal spring clips.

Step 3: Release the Air Box Clips

• Use your fingers to unclip the metal retaining clips on the air filter box lid.
• Pull each clip outward and away from the lid until it releases.
• No socket or screwdriver is normally needed for the Tucson air filter box clips.
• If a clip feels stuck, use your gloved hand to gently wiggle it loose. Do not force it hard.

Step 4: Open the Air Filter Box Lid

• Use both hands to gently lift the air filter box lid upward just enough to access the filter.
• Do not pull hard on the connected intake tube or wiring nearby.
• The lid may only open a few inches, which is enough to remove the filter.
• Lift only as much as needed.

Step 5: Remove the Old Engine Air Filter

• Use your hand to pull the old engine air filter straight up and out of the lower air box.
• Notice the filter orientation before removing it. The new filter must sit the same way.
• Check the old filter for heavy dirt, leaves, oil, or rodent debris.

Step 6: Clean the Air Filter Box

• Use a shop vacuum with crevice nozzle to remove loose leaves, dust, or debris from the bottom of the air box.
• Use a clean microfiber towel to wipe the sealing edge where the filter sits.
• Do not let dirt fall into the intake tube opening.
• Do not spray cleaners into the air box.

Step 7: Install the New Engine Air Filter

• Use your hands to place the new engine air filter into the lower air box.
• Make sure the rubber edge sits flat all the way around.
• The filter should not be bent, crushed, or pinched.
• If the lid does not close easily, remove the filter and reseat it.
• A flat seal prevents dirt entry.

Step 8: Close and Secure the Air Filter Box

• Use both hands to lower the air filter box lid into place.
• Make sure the rear tabs of the lid are properly seated in the lower box before clipping the front side.
• Use your fingers to snap each metal retaining clip back onto the lid.
• Confirm every clip is fully locked.
• No torque specification applies because this air box uses hand-operated clips.

Step 9: Final Visual Check

• Use your eyes and hands to confirm the air box lid is fully closed with no gaps.
• Check that the intake tube is still attached and not pulled loose.
• Remove all tools, the old filter, and towels from the engine bay.
• Close the hood firmly.
