Step-by-Step Process
Step 1:
Open the driver's side door and locate the red hood-release handle on the lower dash panel, just left of the brake pedal.
Pull the handle towards you until the hood pops.
At the front of the vehicle, release the secondary latch above the grille area, and lift the hood.
Step 2:
Pull straight up on the engine cover to release it from the rubber grommets.
Lift at the front corners to remove the front panel.
Remove the engine cover and set it aside.
Identify the screws shown in the second image.
Step 3:
Attach an E10 socket to a ratchet and remove the bolts securing the bracket along the top edge of the engine cover.
Take care not to drop the bolts, as you will need them to reinstall the bracket.
You may need some WD-40 to loosen them.
Step 4:
Push the locking tab on the MAF sensor to the right until it fully extends.
Disconnect the (MAF) sensor and lift the sensor off the intake hose.
Set it aside on the right, resting on top of the hose, and keep the tip clean.
Do not get the tip dirty!
Step 5:
Use a flathead screwdriver to loosen the intake tube clamp until it releases.
You'll hear and see it snap apart, and you can reuse it.
Step 6:
Remove the air filter intake tube.
Lift the entire filter straight up out of the engine block and place it sideways in your workspace.
Step 7:
Loosen the three perimeter Torx T-25 screws securing the air filter lid.
Leave the screws in place, as they are spring-loaded. Just loosen them completely without pulling them out.
Step 8:
Use the bottom hinge to open the engine air filter from the top, flipping it open like a book.
Position the part with the filter facing upright.
Step 9:
Lift the old filter straight up and out, keeping it level to prevent debris from falling into your workspace.
Clean out any debris with a broom or other cleaning tool.
Ensure the male and female connectors on the new filter and the housing match.
Step 10:
Place the new engine air filter back into the housing.
Ensure the new filter is seated with the rubber seal flat all around.
Close the lid evenly and reinstall all of the lid screws (avoid overtightening plastic).
Slide the intake tube fully onto the snout and align the E-10 bolt mounts.
Step 11:
Reattach the filter to the bracket before moving on!
Reassemble the lid, clamp, hoses, and bracket. Use flat-tipped pliers to squeeze the clamp together until you hear a click indicating a secure connection.
Finally, reconnect your (MAF) sensor to the hose.
FINISHED! Double-check that everything is securely attached. Start your car and listen for any unusual sounds.
