🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Open the Hood

• Use your hand to pull the hood release lever inside the cabin near the driver-side lower dash area.
• Use your fingers to release the secondary hood latch at the front of the hood.
• Raise the hood and secure it with the hood prop rod if equipped.
• Make sure the hood is stable.

Step 2: Locate the Engine Air Filter Box

• Use your eyes to find the black plastic air filter box in the engine bay.
• The box is connected to a large black intake tube that runs toward the engine.
• The air filter box lid is held by metal spring clips. A spring clip is a small metal latch that snaps the lid closed.

Step 3: Release the Air Filter Box Clips

• Use your fingers to flip open the metal retaining clips on the side of the air filter box lid.
• Do not force the clips. They should pop loose with steady finger pressure.
• If dirt is packed around the clips, use a shop towel to wipe the area first.

Step 4: Lift the Air Filter Box Lid

• Use both hands to gently lift the air filter box lid upward just enough to access the filter.
• Do not yank the lid or pull hard on the attached intake tube.
• There are no torque specs for this step because the filter box uses clips, not bolts.

Step 5: Remove the Old Engine Air Filter

• Use your fingers to lift the old engine air filter straight out of the lower air box.
• Notice the filter’s direction and shape before removing it fully.
• Check for leaves, sand, or debris inside the bottom of the air box.

Step 6: Clean the Air Filter Box

• Use a vacuum with crevice nozzle to remove loose debris from the bottom of the air filter box.
• Use a shop towel to wipe the sealing edge where the filter sits.
• Do not push dirt into the intake tube opening.
• A clean seal prevents unfiltered air leaks.

Step 7: 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 should fit neatly without bending, crushing, or forcing it.
• If it does not sit flat, lift it out and reposition it.

Step 8: Close the Air Filter Box Lid

• Use both hands to lower the air filter box lid evenly onto the new filter.
• Make sure the lid is fully seated and not pinching the filter edge.
• Use your fingers to snap the metal retaining clips back into place.
• There are no torque specs for the clips because they latch by hand.

Step 9: Final Visual Check

• Use your eyes and hands to confirm the air filter box lid is closed evenly on all sides.
• Use your hand to gently check that all clips are locked.
• Use a shop towel to remove any loose dust from the surrounding area.

• 📅 Replace the engine air filter more often if driving in dusty areas, construction zones, or heavy traffic.
