Procedure
Set the parking brakes, park your Hyundai in a secure location, and let the engine cool.
Closed Hood Open the hood next. Clean the region around the ignition coils and the vicinity of the spark plugs.
- Negative battery terminal disconnected. It is safe to unplug the negative battery terminal as you will be dealing with the electrical system.
- Engine cover removal. Up to four 10mm bolts, which are accessible from the top of the engine, are used to secure it in place. Open up the engine cover if there are no bolts on the top.
Eliminate the ignition coils. The ignition coils should then be disconnected after removing the engine cover. By depressing the locking tab and drawing the connector away, you can unplug the ignition coil connector.
- To remove the bolt holding the coil in place, use a 10 mm socket. This car has a coil-on-plug layout. Therefore, each spark plug will have one coil. Pull the ignition coils out after removing the bolt and connector. If the ignition coil still won’t rise, try raising it up and out after a slight twist.
Delete the spark plug. Before removing the spark plugs, blow debris out of the recess.
- To remove the spark plugs from the engine, use the spark plug removal tool, ratchet, and 3/8″ extension. To take out the spark plug, turn counterclockwise. A magnetic pickup tool may be required to remove the spark plug.
Replace the spark plugs. Installing the new spark plug is now necessary. Using a spark plug gapping tool to check the gap is a recommended practice. While some spark plugs, like copper plugs, might be pre-gapped, others might not.
- The electrical connector should be attached to each ignition coil after installation. Put the engine cover back on.
- Remove all of the engine’s tools.
- Start the car’s engine and give it a test drive.
Use an OBD-II scanner to erase any codes if a faulty spark plug or ignition coil caused the check engine light to come on.

What other goods should be suggested when changing spark plugs?
The threads of the spark plugs can avoid becoming permanently bonded to the cylinder head, spark plug boot, or surrounding wires by using an anti-seize lubricant or dielectric oil. Even a few drops on the spark plug threads can help!
Note: When using dielectric grease, you’ll probably need to lessen the torque using a torque wrench.
How can spark plugs be checked without removing them?

What symptoms indicate a damaged spark plug?
It is not unexpected that the symptoms of malfunctioning plugs are somewhat alarming given the critical role that spark plugs play in the operation of your car. Several typical signs you could observe include:
- pinging, rattling, or knocking noises. You may hear strange noises as a result of the power of the pistons and improper combustion when spark plugs start to misfire. High speeds are achieved via pistons. Constant rattles, pings, or knocks may result from the spark plug firing at the incorrect moment.
- difficult car start. Your spark plugs could not be operating properly, which can cause misfires and irregular performance if your car is hard to start or just seems jerky and disjointed.
- diminished performance Your spark plugs don’t stop working while you’re cruising, even when you accelerate and shift gears. Your car’s performance won’t be at its peak if the spark produced by this tiny plug isn’t operating at full capacity.
- poor fuel efficiency. There are many factors that can contribute to poor fuel efficiency, but malfunctioning spark plugs can waste fuel if your car doesn’t get the right spark at the right moment.
We advise having your car inspected if you see any of these signs in order to stop further issues. For your car to start and stay powered, healthy spark plugs are essential.

Should I switch to spark plugs instead of ignition coils?
Spark plugs and ignition coils work in tandem. The other cannot work correctly if either one fails. So, should spark plugs be used in place of coil packs? It varies.
The spark plugs are the part that needs to be changed the most frequently along with the ignition coils. Coils can be overworked by worn spark plugs, and the effort needed to replace both parts is frequently overlapped. It is advisable to repair both parts at once if your worn-out spark plugs caused your ignition coils to fail.
However, unless there are indications that they are malfunctioning, replacing your ignition coils at the same time that you replace your spark plugs as part of routine maintenance is not necessary.
It is advised to replace the wires in ignition/spark plug systems if they look to be brittle, worn, or broken. If moisture (such as an oil leak) has harmed the ignition coils, the moisture source should also be fixed in order to prevent the problem from reappearing too soon.
The moment you notice a problem with your ignition coil, call a professional. Should I replace my ignition coils with spark plugs? is one of the first queries you should put to your expert. Have your mechanic check your car to see whether the ignition coils and spark plugs need to be replaced.
How firmly should spark plugs be installed?
- Verify that the spark plug’s thread reach is the appropriate one for your engine.
- Clear the debris from the cylinder head’s gasket seal.
- Before using a spark plug wrench, tighten the spark plug with your fingers until the gasket touches the cylinder head. (Taper seat: Add an additional 1/16 turn.)
Do I have to unplug the battery to replace the spark plugs?
When trying to replace the spark plugs in their car, this is a common query that individuals have. The battery does not need to be disconnected in order to replace the spark plugs, is the response. You may just detach the spark plug from the engine and then remove the spark plug wire from it.
Additionally, when working on anything electrical, it’s crucial to disconnect the negative connection of your automobile battery. Any mishaps will be less likely as a result. Before changing your spark plugs, make sure the engine of your automobile has completely cooled. By doing this, it will be simpler to remove the plugs and the ignition coil boot or spark plug wire.
What signs indicate a faulty spark plug?
A car owner may also have to spend money replacing a catalytic converter as a result of neglected spark plugs. When the plugs are damaged, they are unable to effectively burn the fuel in the combustion chamber. When this happens, the car uses more fuel on a regular basis to function properly, which reduces fuel economy. Because of this, a car owner will notice that when the spark plugs are worn out, additional strain is placed on more than just the engine. A car owner will spend a lot of money replacing those degraded plugs as they will need to purchase more and more fuel.
