🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Locate the air filter box

• Find the black plastic air filter box (air cleaner housing). It’s connected to the large intake tube going toward the turbo.
• Use safety glasses and nitrile gloves before you start.

Step 2: Release the air filter box fasteners

• Depending on the housing style, loosen the fasteners on the lid:
• Use a Torx T20 screwdriver to loosen the screws (they usually stay captured in the lid).
• If your housing uses clips, pop them open with a flat-blade screwdriver (gently so you don’t snap them).
• If a small bracket blocks access, remove it with a 10mm socket, 1/4" ratchet, and 1/4" extension (3").

Step 3: Open the housing and remove the old filter

• Lift the lid of the air box enough to pull the filter out. You usually don’t need to fully remove the lid.
• Pull the old filter straight up and out.
• Use a shop towel to wipe out loose dust in the bottom of the box.
• Don’t let debris fall into the intake tube.

Step 4: Install the new air filter

• Place the new filter into the lower half of the air box.
• Make sure the filter’s rubber edge sits flat all the way around (no corners folded).
• If the filter has an “UP” or airflow marking, orient it the same way as the old one.

Step 5: Close the housing and secure everything

• Lower the lid back into place.
• Tighten the screws with a Torx T20 screwdriver until snug (do not overtighten; it’s plastic).
• Reinstall any bracket you removed using a 10mm socket, 1/4" ratchet, and 1/4" extension (3").
• Torque to 10 Nm (89 in-lbs) for typical 10mm air box/bracket bolts (snug if you don’t have a torque wrench).

✅ After Repair

• Start the engine and let it idle for 20–30 seconds.
• Listen for any whistling/hissing that could indicate the air box lid isn’t sealed.
• Confirm the lid is fully closed and all screws/clips are secured.
