🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Remove the upper engine cover (if equipped)

• Use your hands to pull up on the engine cover at the corners to release the rubber grommets.
• If your cover uses fasteners, remove them with a Torx T25 driver.
• Set the cover aside where it won’t get stepped on.

Step 2: Locate the airbox and loosen the airbox cover fasteners

• Find the airbox at the front/upper area of the engine bay (it’s the large black plastic box feeding the turbo inlet).
• Remove any plastic push-clips on the intake snorkel/ducting using a trim clip removal tool.
• Loosen/remove the airbox cover screws using a Torx T25 driver or Torx T30 driver (BMW commonly uses Torx here).
• Tip: Keep screws in a small tray.

Step 3: Lift the airbox lid to access the filter

• Gently lift the airbox lid straight up.
• If the lid feels stuck, use a pick tool to help unseat a stubborn rubber edge seal (be gentle so you don’t tear it).
• Do not yank on any attached tubes or wiring.

Step 4: Remove the old air filter

• Pull the old filter straight out of the airbox.
• Use a flashlight to look inside the lower airbox for leaves, sand, or bugs.

Step 5: Clean the airbox sealing surface

• Use a shop vacuum with hose to vacuum out loose debris from the lower airbox.
• Wipe the sealing lip (where the filter sits) with a clean microfiber towel.
• Make sure nothing falls into the intake tract.

Step 6: Install the new air filter

• Place the new filter into the airbox in the same orientation as the old one.
• Make sure the filter edge sits fully down and evenly all the way around (this prevents unfiltered air leaks).

Step 7: Reinstall the airbox lid and fasteners

• Lower the airbox lid back into place, ensuring the lid seal is seated evenly.
• Install and tighten the screws with a Torx T25 driver or Torx T30 driver.
• Final-tighten using a 1/4" torque wrench (2-20 Nm range): Torque to 5 Nm (44 in-lbs).
• Reinstall any push-clips using a trim clip removal tool (press them back in by hand).

Step 8: Reinstall the engine cover

• Line up the cover with its mounting points and press down firmly by hand until it snaps into the grommets.
• If it had screws, reinstall them with a Torx T25 driver and snug them by hand (do not overtighten).

✅ After Repair

• Start the engine and let it idle for 15-30 seconds.
• Listen for any hissing/whistling that could indicate the airbox lid isn’t sealed.
• If you hear a leak, shut the engine off and re-check that the filter is seated and the screws are evenly tightened.
