🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Locate the air filter housing

• Look for the black plastic airbox (air filter housing) in the engine bay. It’s the box connected to the intake tube leading toward the engine.
• Take a photo before removal.

Step 2: Open the airbox

• If your airbox uses clips: use a flat trim tool to gently pop the clips open.
• If your airbox uses bolts/screws: use a 10mm socket with a 1/4" ratchet and 6" extension to loosen/remove the fasteners.
• Lift the airbox lid straight up just enough to access the filter (you usually do not need to remove the whole airbox).
• Don’t force the lid; check for hidden fasteners.

Step 3: Remove the old air filter

• Pull the filter straight out by hand.
• Use a shop light to inspect the inside of the airbox for leaves or debris.
• If you see loose debris, remove it carefully by hand—do not push debris deeper into the intake.

Step 4: Install the new air filter

• Place the new filter into the airbox in the same orientation as the old one.
• Make sure the filter’s sealing edge sits flat all the way around (no corners folded).
• A bad seal lets dirt bypass the filter.

Step 5: Reassemble the airbox

• Lower the airbox lid back into place, aligning tabs and edges.
• Re-latch the clips by hand, or reinstall the fasteners using a 10mm socket and 1/4" ratchet.
• Tighten fasteners snugly—do not over-tighten (airbox plastic can crack).

Step 6: Final check

• Do a quick visual check that nothing is left loose around the intake tube.
• Close the hood securely.

✅ After Repair

• Start your Supra and let it idle for 30 seconds.
• Listen for whistling/hissing near the airbox area (can indicate the lid isn’t sealed).
• If you get a warning light after this job, recheck that the airbox lid is fully seated and all clips/fasteners are secured.
