📋 Before You Begin

• Park your F-150 on level ground, shift into Park, engage the parking brake, and switch off the ignition.

• Locate the black air-cleaner box on the passenger side of the engine compartment.
• Compare the new filter with the old filter before installation. Their dimensions and sealing edges must match.

🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Open the air-cleaner box

• Put on the safety glasses and nitrile work gloves.
• Release the metal retaining clips around the air-cleaner cover by hand. Pull each clip outward and away from the cover.
• Lift the cover enough to access the filter. The intake tube normally has enough movement, so disconnecting it is unnecessary.
• Do not pull on the wiring or the mass airflow sensor. The mass airflow sensor measures the air entering the engine.

Step 2: Remove the old filter

• Note how the old filter sits inside the lower housing.
• Lift the filter straight out by hand without shaking dirt into the clean side of the housing.
• Use the clean lint-free cloth to cover the clean-air opening temporarily.
• Keep debris out of the intake opening.

Step 3: Clean the filter housing

• Use the portable vacuum with crevice attachment to remove leaves, sand, and loose dirt from the bottom of the housing.
• Use the clean lint-free cloth to wipe the filter-sealing surface.
• Remove the cloth covering the intake opening before installing the new filter.
• Do not blow compressed air toward the intake or mass airflow sensor.

Step 4: Install the new filter

• Place the new engine air filter into the lower housing by hand in the same orientation as the old filter.
• Press lightly around the filter’s rubber sealing edge. It must sit flat without folds or gaps.
• Do not add oil to a standard dry replacement filter.
• A pinched seal can allow dirt into the engine.

Step 5: Close the air-cleaner box

• Align the cover tabs with the slots in the lower housing by hand.
• Lower the cover while checking that the filter remains seated evenly.
• Secure every metal retaining clip by hand. Each clip should lock firmly over the cover edge.
• Check around the complete housing seam. There should be no visible gap.
• No fastener torque specification applies because the filter cover uses hand-operated retaining clips.

✅ After Repair

• Remove all tools and the old filter from the engine compartment.
• Start the engine and let it idle for approximately one minute.
• Listen for a loud sucking or whistling sound, which can indicate an improperly closed housing.
• If the check-engine light appears, switch off the engine and verify that the cover is fully seated and no sensor wiring was disturbed.
• Check the filter during routine oil services and replace it sooner when driving in dusty conditions.
