🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Locate the Air Filter Housing

• Put on safety glasses and nitrile gloves.
• Stand at the front of your F-150 and look toward the passenger side of the engine bay.
• Find the black plastic air filter housing connected to the large intake tube.
• Take a quick photo first.

Step 2: Release the Air Box Cover Clips

• Use your hands to flip the metal or plastic retaining clips away from the air box cover.
• A retaining clip is a small latch that locks the air box lid closed.
• Do not force the clips. They should release with firm hand pressure.

Step 3: Open the Air Box Cover

• Use both hands to gently lift the air box cover enough to access the filter.
• Do not pull hard on the intake tube or nearby wiring.
• If the cover feels stuck, check that all clips are fully released.

Step 4: Remove the Old Engine Air Filter

• Use your hands to lift the old engine air filter straight out of the lower air box.
• Note which side faces upward so the new filter goes in the same way.
• Check for leaves, sand, or loose debris inside the lower air box.

Step 5: Clean the Air Box

• Use a shop vacuum with crevice nozzle to remove loose debris from the lower air box.
• Use a clean microfiber towel to wipe the sealing surface where the filter sits.
• Do not let dirt fall into the intake opening.

Step 6: Install the New Engine Air Filter

• Use your hands to place the new engine air filter into the lower air box.
• Make sure the rubber edge sits flat all the way around.
• The filter must not be folded, pinched, or sitting crooked.
• A flat seal prevents dust leaks.

Step 7: Close the Air Box Cover

• Use both hands to lower the air box cover back into place.
• Make sure the cover tabs are seated correctly before closing the clips.
• Use your hands to snap each retaining clip back into the locked position.
• No torque spec applies because this air box uses hand-operated clips.

Step 8: Final Visual Check

• Use your hands to gently wiggle the air box cover and confirm it is secure.
• Check that no tools, towels, or packaging are left in the engine bay.
• Close the hood firmly.

• No computer reset, scan tool, or relearn procedure is required for this engine air filter replacement.
