4 cylinder 2.2 liter? there will be a cover that can be removed on top of the valve cover. Once that is removed the spark plugs can be accessed.

I’m happy to assist further over the phone at https://www.6ya.com/expert/jeremy_d728a59f986299fa

Very back of engine on passenger side at the very end of the valve cover between valve cover and fire wall.

you have to remove the plastic cover attached to top of valve cover,once removed you'll see where coils drop into cylinder head through valve cover.remove and plugs (5/8 socket)sit down below coils.

You didn't specify whether you have the (4) cylinder or the (6) cylinder engine..... I have a 2004 Hyundai Sonata 2.4L 4 cylinder and I just changed the spark plugs in it. I believe that the 2005 2.4L engine is the same. To locate and change the (4) spark plugs on a 2004 Hyundai 2.4L 4 cylinder engine: Remove the (4) 12mm bolts from the decorative plastic engine cover. Remove plastic cover from engine and place it off to the side out of your way. Standing in front of the car, the (4) spark plugs are located laterally (left to right) in the recessed area underneath where the plastic engine cover was removed. Note: This engine has (2) coils....They are located above spark plugs number (2) and (3) from left to right. Starting with the fist spark plug on the left: Remove the spark plug cable by pulling straight up on the insulated connector. Using a spark plug socket, remove the old spark plug and install a new one in it's place. To access the second spark plug from the left, remove the electrical connector and the spark plug cable wire from coil number (1) and then remove the (2) 12mm bolts that secure the coil to the engine. Spark plug number (2) is located directly under the coil. Lift the coil straight up removing the insulated connector from spark plug number (2). Using a spark plug socket, remove old spark and install a new one in it's place. Repeat same procedures for spark plugs number (3) and (4). Note: If you have the (6) cylinder engine, the front (3) sparks pluge are readilly accessible but in order to access the (3) rear spark plugs, you will have to remove the intake manifold

Remove the plastic cover that goes over the engine (the one with the Hyundai logo).
At this point, you will see the cables that goe to each fo the spark plugs.
Noting their position, remove them.
The spark plugs are ready to be removed, turn counterclockwise and replace with manufacturer recomended ones.

Not that simple on newer cars, but you do still need those tools.

Here is a good write-up: Changing Plugs on an Altima that will show you the location of the coil packs that must be removed first (9th picture from the bottom) and what they look like.

Doesn't really need to be done until about the 100,000 mile mark. Do not do it while the engine is hot or even warm. Replace with the factory recommended spark plug. Place a little anti-seize on the threads and some dielectric grease on the top. Be sure you torque them down to the proper setting. I believe it is somewhere around 20 ft. lbs., but if you call the Nissan service desk they should be able to tell you for sure.

there is a cover on top of engine, held by 8 or 10 probably hex bolts, remove cover and the plugs are underneath it.
