🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Locate the air filter box

• 🔸 Stand in front of the car and look to the passenger side (right side as you face the car) of the engine bay.
• The air filter box is a black plastic box connected to a large plastic tube that goes toward the engine.
• Use the flashlight if needed to see the clips and screws around the air box.
• Trace the big plastic intake tube to find the box.

Step 2: Release the air box cover clips

• 🔸 On your Camry, the front edge of the air box cover is held by metal or plastic clips.
• Use your fingers or the flathead screwdriver to gently pry and unclip each clip from the cover.
• Do not bend them too far; they can snap or lose tension.
• Work slowly so the clips don’t fly off.

Step 3: Remove any 10mm bolts holding the air box cover

• 🔸 Some V6 Camry air boxes also have 10mm bolts on the rear or side of the cover.
• Use the 10mm socket, 3" socket extension, and 1/4" drive ratchet to remove any visible bolts on the air box cover.
• Set the bolts aside in a safe place so you don’t lose them.
• Reinstallation torque for air box bolts: 5–7 Nm (44–62 in-lbs)

Step 4: Open the air box cover

• 🔸 Once the clips and bolts are removed, lift the front of the air box cover upward.
• The rear edge of the cover is usually held by plastic hinges or tabs; pivot the cover up without forcing it.
• Do not pull hard on the attached intake tube or any sensor wiring; just open it enough to access the filter.
• Lift only as much as needed to slide filter out.

Step 5: Remove the old air filter

• 🔸 Note how the old filter sits in the box: rubber sealing edge usually faces up, paper pleats downward into the box.
• Grab the filter by one corner and lift it straight up and out using your hand.
• If it is stuck, gently wiggle it a little while pulling.

Step 6: Clean the air box (optional but recommended)

• 🔸 With the filter removed, you’ll see the bottom of the air box.
• Use the shop vacuum with small nozzle to suck out any leaves, dust, or debris.
• Use a clean rag to wipe around the sealing surface where the rubber edge of the filter sits.
• Do not push dirt into the opening that leads toward the engine.
• Keep the vacuum nozzle away from sensitive sensors.

Step 7: Install the new air filter

• 🔸 Take the new engine air filter out of its packaging.
• Make sure the rubber sealing edge is clean and free of damage.
• Place the new filter into the air box with the same orientation as the old one: rubber edge up, pleats down, and edges fully seated in the groove of the air box.
• Check that the filter sits flat and is not twisted or riding up on any side.
• Correct seating is critical for keeping dirt out.

Step 8: Close and secure the air box cover

• 🔸 Swing the air box cover back down, making sure the rear tabs or hinges engage properly with the lower half.
• Check that no part of the new filter is pinched between the cover and the box.
• Reinstall any 10mm bolts you removed using the 10mm socket, 3" socket extension, and 1/4" drive ratchet.
• Tighten the bolts to 5–7 Nm (44–62 in-lbs). This is snug, not very tight.
• Re-latch all clips by pressing them back into place until they click.
• Run your fingers around the seam of the air box to confirm it is fully closed and even.

Step 9: Final under-hood check

• 🔸 Look around the air box and intake tube and confirm no tools, rags, or parts are left behind.
• Make sure all electrical connectors and hoses on the intake tube are untouched and secure.
• Remove the hood prop rod and close the hood firmly.

✅ After Repair

• 🔸 Start the engine and let it idle for a minute. It should run smoothly with no warning lights.
• 🔸 Gently rev the engine once or twice from inside the car; listen for any odd whistling or hissing near the air box that could indicate a poor seal.
• 🔸 Take a short test drive; if the check engine light stays off and the car feels normal, the job is done.
• 🔸 Plan to replace the engine air filter every 15,000–30,000 miles, or more often in dusty conditions like rural or construction areas.
