📋 Before You Begin

• 🅿️ Park your Tucson on level ground and shift to Park.
• 🔑 Turn the ignition fully off and remove the key.
• 🧤 Put on safety glasses and nitrile gloves.
• 📦 Open the hood and locate the engine air filter housing, also called the air box. The air box is the black plastic box connected to the large air intake hose near the front/driver-side area of the engine bay.

🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Open the Hood

• Use your hand to pull the hood release lever inside the cabin, usually near the driver-side lower dash.
• Use your hand to release the secondary hood latch at the front of the hood.
• Lift the hood and secure it with the hood prop rod if equipped.
• Tip: Never trust an unsecured hood.

Step 2: Find the Air Filter Housing

• Use your eyes and hands to locate the black plastic air box connected to the intake tube.
• The intake tube is the large ribbed hose that carries filtered air toward the engine.
• Do not remove the intake hose unless the air box cover cannot lift enough to access the filter.

Step 3: Release the Air Box Cover Clips

• Use your hand to unclip the metal retaining clips on the air box cover.
• A retaining clip is a spring-style latch that holds the cover tightly closed.
• Pull each clip outward gently until it releases from the cover.
• No bolt torque is required because these are hand-release clips.

Step 4: Lift the Air Box Cover

• Use both hands to lift the air box cover just enough to access the filter.
• Do not pull hard on the attached intake hose or wiring nearby.
• If the cover feels stuck, use your hand to check that every retaining clip is fully released.

Step 5: Remove the Old Engine Air Filter

• Use your hand to lift the old engine air filter straight out of the air box.
• Note the direction and shape of the old filter before removing it fully.
• Check for leaves, sand, or debris inside the bottom of the air box.

Step 6: Clean the Air Box

• Use a shop vacuum to remove loose dirt, leaves, 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 push dirt into the intake tube opening.
• Tip: Keep debris out of the engine.

Step 7: Install the New Engine Air Filter

• Use your hands to place the new engine air filter into the air box.
• Make sure the rubber sealing edge sits flat all the way around.
• The filter should drop in naturally without forcing it.
• If it does not sit flat, remove it and rotate it until it matches the housing shape.

Step 8: Reinstall the Air Box Cover

• Use both hands to lower the air box cover evenly over the new filter.
• Make sure no part of the filter seal is pinched outside the cover.
• Use your hand to snap each retaining clip back into place.
• No torque spec applies because the cover is secured by clips, not bolts.

Step 9: Final Visual Check

• Use your eyes and hands to confirm the air box cover is fully seated.
• Check that all retaining clips are latched.
• Confirm the intake hose is still connected and not twisted or loose.

✅ After Repair

• ✅ Start the engine and let it idle for about 30 seconds.
• 👂 Listen for any loud hissing sound near the air box, which can mean the cover is not seated correctly.
• 🔍 If the engine runs rough or you hear a hiss, turn the engine off and recheck the filter position and air box clips.
• 🗓️ Replace the engine air filter about every 15,000-30,000 miles, sooner in dusty conditions.
