Step-by-step instructions

Pull the hood release lever located on the car's driver's side where the pedals are until you hear the latch release with a click.
The lever closest to the door will have a symbol that looks like a car with a raised hood.
Go to the front of the vehicle and press the latch under the hood to the side to raise the hood.
Make sure to secure it in place.
This will help prevent injuries.

Using your thumb, press the tab on the mass air flow sensor.
Once the tab lock is released, pull up on the connector to detach the mass air flow sensor connector, which is located on top of the air filter housing.

Remove the smaller hose, the breather hose, by wiggling it off the air filter housing.
Wiggle and pull away from the air filter housing.

Using the flat-head screwdriver, loosen the hose clamp attached to the air intake hose counterclockwise (lefty loosie).
You do not need to remove the clamp completely, only loosen enough to remove the hose.

Remove the hose from the air filter housing.
Like with the breather hose, wiggle and pull away from the air filter housing.

Press the two clips on the front of the air filter housing closest to the front end of the car towards yourself and down to release them.
Lift the cover while pulling it towards yourself to remove it. Set aside for next steps.

Lift the old air filter out by pulling away from the housing in an upward motion.
Dispose of the old air filter. In many places, air filters are accepted at local recycling plants.

Pull the new air filter out of the box, making sure it matches the old Filter's shape and size.
Place the new air filter inside the housing, with the rubber side up and the fans facing down.

To replace the cover of the air filter housing, line the three pegs up with the holes in the back and push in and down to snap into place.
Reclip the housing clips by pushing them up and over the lip of the air filter housing. There should be a snapping sound.
Double-check the cover placement if the clips are not going back in place.

Reattach the air intake hose by pressing it and wiggling it toward the air filter housing.
Make sure the hose clamp stays where the screw-lock is on top.
Tighten the hose clamp by using the flat-head screwdriver in a clockwise direction (righty tighty).
You should only tighten the clamp until the hose is secure. If you tighten too much, the hose could be damaged.

Reattach the breather hose by pressing it and wiggling it back onto the stem you detached it from, pushing toward the air filter housing.

Line the mass air flow sensor connector up with the plug-in you removed it from.
Press down until the connector snaps into place and locks.
At this point, you are done and can close the hood of the vehicle.

Conclusion

Please make sure all parts are fully secured at the end before closing the car's hood.
