Keep in mind the right firing order:
1 - 8 - 7 - 2 - 6 - 5 - 4 - 3

* Remove the appropiate spark plug wire boot(s) from the spark plug.
1.1. Twist the spark plug boot 1/2 turn.
1.2. Pull ONLY on the spark plug boot or use a tool designed for this purpose in order to remove the spark plug wire boot from the spark plug.

* Loosen the spark plug 1 or 2 turns. (left side shown, right similar).
* Brush or air blast away any dirt from around the spark plug.
* Remove the spark plug. If removing more than 1 plug, place each plug in a tray marked with the corresponding cylinder number.
* Keep the GAP .040"

Hope this helps.

Spark plugs are some of the most important parts of your car. Engines flatly don't work without them. Please follow the bellow instructions as to how you should replace the spark plugs in your car:-

First you have to remove the negative battery cable. Allow the engine to cool down.Now gain access to the spark plug wires which are located on the side of the engine. Carefully lift the plastic cover on the side to access the spark plug wires.You have to grasp the spark plug wires by the boot of the wire. The wire boot is the cap that connects directly to the Silverado engine. Now turn the boot halfway to the right and then halfway to the left to loosen the wire from the plug. Do it efficiently.

Now attach the socket to the spark plug. Turn the wrench to the left to unscrew and remove the old spark plug. Clean the inside of the wire boot with the wire brush. Lightly spray the boot and threads of the new spark plug with silicone lubricant. After that insert the new spark plug into the engine and manually screw it in place. Use the tension tester tool to find the tension of the spark plug. The appropriate tension level is printed on the spark plugs packaging. Adjust the spark plug to set the required tension. Replace the spark plug wires. Turn the plug back and forth to lock it in place. Replace the plastic cover back onto the engine and return the battery cable to the battery.

Thank you for contacting

Please get back to us if you have any further query.

Have a nice day.

How to change the spark plugs on my 2009 Hyundai Sonata 4 cyl.

remove 1 spark plug wire from the plug. Find a socket that fits the spark plug and connect it to the socket wrench. Put the socket on the spark plug and turn counter clock wise until the old spark plug is removed. Check the gap on the new replacement plug ( make sure you have the correct plug first). Put the new spark plug into the hole that the old 1 came out of and turn clockwise by hand making sure it is in straight, then tighten it clockwise until tight.( WARNING: DO NOT OVER TIGHTEN THE PLUG OR YOU WILL BREAK IT). replace the spark plug wire. repeat the process with the other 3 spark plugs. Start the vehicle. If you are replacing the wires, take off 1 wire at a time, match up the size and replace the old with the new.

Attention to spark plugs

Pay attention to what spark plug comes from what cylinder, and save the old spark plugs. The cylinders are numbered from 1 to 8 as follows: Front of car Left side - right side Cylinder Bank 2 - Cyliner Bank 1 5 - 1, 6 - 2, 7 - 3, 8 - 4, Rear of car. The reason for keeping track of the old spark-plugs is it can later provide important information to a person who knows how to "read" spark-plugs, if the engine ever develops a problem. Also it is good practice to put the coils back in the same places those were.

Causes cylinder misfire

Most common cause is an old spark plug that burnt out the coil. Spark plugs should be replaced every 100,000 miles. If the plugs are old replace the spark plugs and swap the coil with cylinder 6. If the code jumps to cylinder 6 you know you have a bad coil.

How do you install spark plugs

do one at a time. pull the wire off of the old spark plug. use a spark plug socket with an extension and a ratchet to remove the old plug. now put the new plug back into where the old one just came out. replace the wire and move to the next. this practice assures you won't get the firing order mixed up

Changed the spark plugs and the old ones were covered in oil

i'm guessing that your car is a 4-cylinder. this is common for inline 4-cylinder engines. since the spark plug holes usually go through the valve cover, the valve cover gasket will leak and collect in the spark plug holes. to fix this you will have to replace the valve cover gasket.

I can't find the spark plugs in my 2005 sonata

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.
