8. Hope this helps, as far as spark plugs on backside of of engine, it just depends. Some people rock the engine forward to get at rear plugs. Sometimes I crawl underneath see if easier to reach plugs? There can be safety issues working under a vehicle. Safety is your responsibility. Your local auto store should have whatever tools you need.

Things you will need
Spark Plug Socket And Wrench of the correct size for your spark plugs


Basic Instructions.
Step 1
Locate your spark plugs
look for other obstructions besides your spark plug wires
if you have any other obstructions you will need to remove them as well to gain access to your spark plugs.
Step 2
Remove the spark plug wire for one single spark plug at a time.
this will insure you will not replace the wrond spark plug wire to the incorrect spark plug,
if not done this way you could change the firing order of your engine.
Step 3
With your spark plug Socket and wrench rotate the spark plug in a counter clock wise direction for removing.
Step 4
After you have removed your spark plug insert your new replacement spark Plug into your spark plug socket before inserting it into the correct location. spark plug sockets are made to hold on to the spark plug for easy removal and install.
Step 5
insert your new spark plug,
before you rotate your spark plug for tightening rotate the spark plug a 1 quarter turn in the counter clock wise direction, then start tightening the spark plug by rotating it in a clockwise direction
This will insure you will not strip the threads.
Step 6
Continue rotation your spark plug in the clock wise direction untill snug, then with just a lil more pressure tighten it up just a little more.
be sure to not put to much force on the spark plug after it has been snug, you just have to apply a little more pressure but not to much that could cause it to break.
Step 7
After tightening the spark plug replace the correct spark plug wire.
then move on to the next spark plug and follow the same instructions.

if you have any other visiable obstructions preventing you access for replacing your spark plugs you will need instructions on how to remove them parts. i have just instructed you on how to remove and reinstall the spark plugs only.

For 2007 Mercury Milan 3.0L SFI DOHC 6cyl the upper intake manifold must be removed to access the RH spark plugs only.

1. Remove the upper intake manifold, if removing the RH spark plugs. Refer to the Intake Manifold procedure in the Engine Mechanical Section
2. Disconnect the 6 ignition coil-on-plug electrical connectors.
   NOTE When removing the ignition coil-on-plugs, a slight twisting motion will break the seal and ease removal.
   
3. Remove the 6 bolts and the 6 ignition coil-on-plugs.
   WARNING Only use hand tools when removing or installing the spark plugs, or damage can occur to the cylinder head or spark plug.
   NOTE Use compressed air to remove any foreign material in the spark plug well before removing the spark plugs.
4. Remove the 6 spark plugs.

To install:

1. Inspect the spark plugs, as outlined in this section.
2. Inspect the 6 spark plugs.
3. Adjust the spark plug gap, as necessary, to 1.32-1.42mm (0.052-0.056 in.).
   WARNING Only use hand tools when removing or installing the spark plugs, or damage can occur to the cylinder head or spark plug.
   
4. Install the 6 spark plugs. Tighten to 15 Nm (11 lb-ft).
   NOTE Apply a small amount of dielectric grease to the inside of the ignition coil-on-plug boots before attaching to the spark plugs.
5. Install the 6 ignition coil-on-plugs and the 6 bolts. Tighten to 7 Nm (62 lb-in).
6. Connect the 6 ignition coil-on-plug electrical connectors.
7. If removed, install the upper intake manifold

Hope helps.

Inspection

Inspect for the correct routing of the spark plug wires. Improper routing may cause cross-firing. Inspect each wire for any signs of cranks or splits in the wire. Inspect each plug wire boot for tearing, piercing, arcing, carbon tracking or a corroded terminal.
If there is any corrosion, carbon tracking or arcing indicated on a plug wire boot or terminal, both the plug wire and component it was connected to should be replaced.

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
