🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Open the Hood

• Use your hand to pull the hood release inside the cabin near the driver footwell.
• Use your hand to release the secondary hood latch at the front of the hood.
• Raise the hood fully and make sure it is secure.

Step 2: Find the Air Filter Box

• Stand at the front of your F-150 and look toward the passenger side of the engine bay.
• The air filter box is the large black plastic box connected to the intake tube.
• The intake tube is the large black tube that carries air from the filter box toward the engine.

Step 3: Remove the Air Box Cover Fasteners

• Use an 8mm socket and 1/4-inch ratchet to loosen the air box cover fasteners.
• The fasteners are usually captive, meaning they stay attached to the cover and do not fully come out.
• Turn each fastener counterclockwise until it spins freely.
• Go slow to avoid stripping plastic.

Step 4: Lift the Air Box Cover

• Use both hands to gently lift the air box cover upward.
• Do not pull hard on the intake tube or wiring near the air box.
• Lift the cover just enough to slide the old air filter out.

Step 5: Remove the Old Air Filter

• Use your hand to pull the old engine air filter straight out of the air box.
• Note the direction and shape of the old filter before removing it completely.
• Check the lower air box for leaves, dirt, or debris.

Step 6: Clean the Air Box

• Use a clean shop towel to wipe out loose dirt from the bottom of the air box.
• Do not let dirt fall into the intake tube opening.
• Do not use compressed air aimed toward the intake tube.

Step 7: Install the New Air Filter

• Use your hands to place the new engine air filter into the lower air box.
• Make sure the rubber seal sits flat all the way around.
• The filter should fit neatly without forcing it.
• If it pinches, reposition it.

Step 8: Reinstall the Air Box Cover

• Use both hands to lower the air box cover into place.
• Make sure the cover tabs and edges are seated correctly.
• Check that the air filter seal is not sticking out from the air box.

Step 9: Tighten the Air Box Fasteners

• Use the 8mm socket and 1/4-inch ratchet to tighten the air box cover fasteners clockwise.
• Tighten them snug only; do not overtighten because the air box is plastic.
• Torque to snug by hand only; do not exceed light hand-tight pressure.

Step 10: Final Visual Check

• Use your hands to gently wiggle the air box cover and confirm it is secure.
• Look around the air box and intake tube to make sure nothing was left loose.
• Use a clean shop towel to remove any dirt from the work area.
