🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Locate the Air-Cleaner Housing

• Find the large black plastic box at the front passenger side of the engine compartment.
• Follow the wide intake duct from the engine toward this box if you need help identifying it.
• Use a clean microfiber cloth to wipe dust from the housing seam.

Step 2: Loosen the Housing Screws

• Use a Torx T25 screwdriver to loosen the four captive cover screws. A captive screw stays attached to the cover after it is loosened.
• Turn each screw counterclockwise until it spins freely.
• Do not force the screws or remove them from the plastic cover.

Step 3: Lift the Housing Cover

• Lift the air-cleaner cover only far enough to access the filter.
• Gently move the attached intake duct with the cover. Do not sharply bend or pull the duct.
• Do not unplug the mass airflow sensor unless extra clearance is absolutely necessary.
• Support the cover; do not strain its wiring.

Step 4: Remove the Old Filter

• Lift the old engine air filter straight out by hand while wearing nitrile gloves.
• Notice how the filter’s sealing edge sits in the housing before removing it completely.
• Keep dirt from falling into the clean-air opening leading toward the engine.

Step 5: Clean and Inspect the Housing

• Use a clean microfiber cloth to wipe loose dust from the lower housing.
• Do not push the cloth into the intake duct.
• Inspect the housing for leaves, cracks, damaged clips, or a distorted sealing channel.
• Do not use compressed air because it can drive dirt into the intake system.

Step 6: Install the New Filter

• Place the new engine air filter into the lower housing in the same orientation as the old filter.
• Press around the entire sealing edge by hand until it sits flat inside its channel.
• Confirm that no part of the filter seal is folded, raised, or trapped outside the housing.
• A flat seal prevents unfiltered air leaks.

Step 7: Refit the Housing Cover

• Lower the cover carefully while keeping the filter centered.
• Check the entire housing seam by sight and touch. The cover must sit evenly with no visible gap.
• Start all four captive screws clockwise by hand with the Torx T25 screwdriver.

Step 8: Tighten the Cover Screws

• Use the Torx T25 socket and 1/4-inch-drive torque wrench to tighten the screws evenly in a crossing pattern.
• Torque to 3 Nm (27 in-lbs).
• Do not overtighten the screws because the plastic housing threads can strip.

• 🔍 If the engine runs roughly or a warning light appears, switch it off and recheck the cover seal and nearby sensor connector.
• 📝 No maintenance reset or filter programming is required.
