Hyundai Repair: How to change spark plugs in a 2003 Sonata, valve cover, spark plugs

Question
My 2.4 four cly. engine has 104,000+ miles on it and I want my husband to change the spark plugs which are original.

Is this something that he can do and what does he have to remove to find and replace them?  He is mechanically inclined which I am not.

Answer
If he's mechanically inclined, this is a simple job which he should be able to do easily.

He'll need to remove one or two engine covers (depending on which covers are on your engine) to access the center area of the valve cover.  Then, he'll need to remove the two ignition coils and plug wires.  The spark plugs will be in the holes in the center of the valve cover.
