🔨 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.
• Use your hand to release the hood safety latch at the front of the hood.
• Raise the hood and secure it with the hood prop rod.
• The air filter housing is the black plastic box on the passenger side of the engine bay.

Step 2: Release the Air Filter Housing Clips

• Use your hand to unclip the metal retaining clips around the air filter housing lid.
• A retaining clip is a spring-style latch that holds the plastic lid closed.
• Do not force the clips. They should snap open by hand.
• Tip: Count the clips before lifting.

Step 3: Lift the Air Filter Housing Lid

• Use your hand to gently lift the top half of the air filter housing.
• You do not need to remove the intake tube for a basic filter change.
• Lift the lid only enough to slide the old filter out.
• Be gentle with the plastic housing so it does not crack.

Step 4: Remove the Old Engine Air Filter

• Use your hand to pull the old engine air filter straight out of the housing.
• Look at how the filter sits before removing it fully.
• The rubber edge of the filter seals against the air box.
• Do not shake dirt into the open air box.

Step 5: Clean the Air Filter Housing

• Use a shop vacuum to remove loose leaves, sand, or dirt from the lower half of the air filter housing.
• Use a clean microfiber towel to wipe the sealing surface where the filter rubber edge sits.
• Do not push dirt toward the engine-side intake opening.
• Tip: A clean seal prevents dust leaks.

Step 6: Install the New Engine Air Filter

• Use your hand to place the new engine air filter into the lower housing.
• Make sure the filter sits flat all the way around.
• The rubber sealing edge must not be folded, pinched, or twisted.
• There are no bolts to torque for this filter housing.

Step 7: Close the Air Filter Housing

• Use your hand to lower the air filter housing lid into place.
• Make sure the lid sits evenly on the filter and housing.
• Use your hand to snap all retaining clips back into place.
• If a clip will not latch, reopen the lid and check that the filter is seated flat.

Step 8: Final Visual Check

• Use your hand to gently tug the housing lid and confirm it is secure.
• Use your eyes to check that no tools, towels, or packaging are left in the engine bay.
• Close the hood securely.
