🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Locate the air filter housing

• The air filter sits in a black plastic airbox in the engine bay, connected to the intake tube (the large plastic/rubber tube that feeds the turbo).
• Use a flashlight to clearly see the airbox seams and fasteners.

Step 2: Remove the engine cover (if equipped)

• Grip the cover with both hands and pull straight upward to release the rubber grommets.
• If it feels stuck, gently lift an edge using a flat trim tool. (A trim tool is a plastic prying tool that helps avoid scratches.)
• Set the cover aside where it won’t get stepped on.

Step 3: Open the airbox

• Locate the screws around the perimeter of the airbox lid.
• Remove/loosen them using a Torx T25 screwdriver (some setups use Torx T30 screwdriver).
• Keep the screws together so none fall into the engine bay.

Step 4: Lift the airbox lid

• Carefully lift the top half of the airbox straight up.
• If the intake tube makes it tight, lift the lid just enough to slide the filter out—don’t force it.
• Don’t yank on any wiring.

Step 5: Remove the old air filter

• Pull the filter straight out.
• Note how it sits in the box (the rubber edge/“gasket” side seals against the airbox).

Step 6: Clean out the airbox (quickly)

• Use a flashlight to check for leaves or sand in the lower airbox.
• Lift debris out by hand with work gloves. Avoid pushing dirt into the intake path.

Step 7: Install the new air filter

• Place the new filter into the lower airbox exactly like the old one came out.
• Make sure the filter’s rubber seal sits flat all the way around (no folds or gaps).

Step 8: Refit the airbox lid and tighten screws

• Set the airbox lid back in place, making sure the edges line up evenly.
• Tighten the screws using a Torx T25 screwdriver or Torx T30 screwdriver.
• Snug them down evenly—do not over-tighten (plastic strips easily).

Step 9: Reinstall the engine cover

• Line up the cover over its mounting points.
• Press down firmly at the corners until it seats.

✅ After Repair

• Start the engine and let it idle for 20-30 seconds.

• Do a quick visual check that no tools are left in the engine bay.
