In this article, we’re going to talk to you about replacing car spark plugs. So stay tuned until the end of the article.
The reason for replacing car Spark Plugs
When a spark is created between the gaps of two electrodes, a small amount of metal from each electrode is corroded. Gradually, over time, the gap becomes so large that the spark can no longer be generated completely. In this situation, various problems arise in the car, such as poor acceleration, check lights and rapping, etc.
Time to evaluate and replace the Spark Plug
For standard nickel-plated spark plugs, automakers may recommend replacing at a distance of 20,000 kilometers. You should always read the intervals of spark plug use described in the manual to find out when to change the spark plugs.
If you do not know when the last time you replaced the spark plugs is, it is necessary to open them and evaluate the spark plug gap and their condition.
Can I change the car’s spark plugs by myself?
Keep in mind that changing worn spark plugs can greatly affect and improve the efficiency and operation of the car’s engine.
You can do this at home with the basic hand tools you have at your disposal. Spark plug replacement intervals can range from 30,000 miles to 100,000 miles, and vary according to the design and type of metals that make the machine and spark plug.
Signs of a bad spark plug ( Failure Symptoms )
- The car has trouble starting.
- Check Engine Light is on.
- The fuel consumption of the car is poor.
- The engine is broken.

How long is the life of spark plugs?
You will need to read the manual to replace the candles. Keep in mind that the time to change the candles may be within 18,000 miles for some cars. For others at 35,000 miles and for others at 100,000 miles. The slowdown, the lack of a motose on, and the rough shutdown are signs that the car may need new candles.
Is it correct to just replace a spark plug?
In general, it is better to replace all the spark plugs. Unless one of the spark plugs has been severely damaged or has suffered a fracture. You should know that changing all the spark plugs at once will help to ensure that the engine has a constant operating level.
Is it better to change spark plugs hot or cold?
If you want to install a new spark plugs when the engine is hot, depending on the application, it is possible to face the spark plugs too loose or too hard. When the spark plugs head is warm, the threads can expand. So when you install a cool spark plugs, it may not be installed properly.
What should be done before changing the spark plug?
Unscrew the wires of your vehicle hood and unscrew the wires from the spark plugs.
Carefully evaluate the plugs to ensure that there is no water or debris around them. Wipe them off if needed to ensure that nothing falls inside the engine cylinder after removing it.
How to understand that the spark plugs are installed correctly?
You should reassess that the gap is set correctly.
Check the manual to find the gap spacing of the spark plug and use a spacer or sensor to assess the distance.
How often do we have to replace the Spark Plugs ?
As none of the previous problems force you to change your candles, you can normally change them every 30,000 to 90,000 miles depending on your candle and car model. The manual will show you the timetable for replacing the vehicle spark plugs.
How to recognize that the spark plugs are broken?
Ask someone to start the engine and see a strong blue spark jump from the plug to the engine.
As this is a weak spark, it may not be enough to overcome cylinder pressures. That is why the inline Tester is a more reliable method of diagnosis.
Why does the car run worse after replacing the Spark Plugs?
The car may have a significant decrease in power, which slows down its acceleration and poor operation.
If the new candles are of little quality or not of the right type of car, this is possible.
Will I notice a difference after changing the Spark Plugs?
Car owners need to replace spark plugs, switches and sensors. When your car receives new spark plugs, its performance increases significantly.
Can Spark Plugs still alive for 10 years ?
The average life of classic spark plugs is not more than 30,000 miles, and platinum and iridium are not more than 55,000 miles.
How long do ngk Spark Plugs last?
The lifespan of these candles is 40,000 to 50,000 miles, NGK says. But you need to know that the driving conditions and changes that occur in the engine of the car are different.
So this rate may change. Normally you should know that you can have 60,000 to 80,000 miles with an unchanged engine.
NGK iridium laser candles have Iridium center and platinum earth electrodes.
Does changing the spark plug wire improve the performance?
Changing spark plugs and wires is a convenient and easy way to restore performance and improve fuel consumption.
According to the National Institute for the excellence of automotive services, they can reduce fuel efficiency by up to 30 percent.
Do you really need a Torque Wrench for Spark Plugs?
It is very important to use the right torque when installing candles to ensure a safe connection.
DENSO always suggests using the torque wrench to achieve proper Torque Adjustment.
Is it necessary to remove the battery when changing the Spark Plug?
- Collect the necessary tools.
- Make sure the engine is cold.
- Disconnect the battery.
- Remove pile wires or screw wire connectors.
- Remove the spark plug with a socket.
- Check the spark plug.
- Install the new spark plug.
- Reconnect the wires / coil connectors in the plug / battery.
What happens if you overtighten the spark plug?
Tightening more than the size of the plugs can cause the plug shell to stretch, which breaks the gas seals and leads to pre-ignition or explosion. In addition, excessive torque can cause the ceramic insulation in the metal shell to loosen and most likely come out of the cylinder head during engine operation.
What happens if oil enters the spark plug well?
The most common reason for the oil on the spark plugs is the leakage of the valve cover gasket.
When the seals around or next to the spark plugs begin to leak, the oil can penetrate the spark plug Wells. You should know that this oil should not enter the cylinder. This reduces the space inside the combustion chamber, which can cause hydrolock.
How far apart are the spark plugs?
Simply put, the gap is the space between the central and lateral electrodes.
This is the axial distance and determines the intensity of the spark, which is very important for efficient combustion. The car manual offers an ideal distance, typically between 0.028 inches and 0.060 inches.
Can a beginner change spark plugs?
If you are not comfortable with it, take your car to a specialist.
But if your engine has easy access to the back bank, then most likely you can do it yourself. It is only necessary to correctly slit the spark plugs and use a torque wrench.
Do new spark plugs improve fuel economy?
Worn-out spark plugs can reduce the mileage of gasoline by up to 30%.
Manufacturers make spark plugs to last about 100,000 miles.
It is best to change the spark plugs early, between 30,000 and 60,000 miles.

Yes, in some situations candles can increase horsepower.
Do new spark plugs make the car work better?
Keep in mind that machines that have been manufactured since 1996 have OBD II troubleshooting systems that track incomplete combustion and turn on the warning light.
Also, new spark plugs can significantly improve cold setup.
Worn or dirty spark plugs require a higher voltage to have a strong spark to start the car.
How to test a spark plug without a tester?
This should happen with the removal of the ignition wire.
Reattach the ignition wire to the top of the loose pile, then place the pile so that the lower metal body is in contact with the metal part of the engine cylinder head. Turn the engine over and notice a gap in the tip.
Can you clean the spark plug?
Inspect your spark plug.
If the spark plug is just a little dirty, you can wipe it with sandpaper. You can start by removing any kind of garbage in the external part of the spark plug.
Next, it is necessary to use sandpaper 220 to gently remove the sediment. It is necessary to do it slowly. Because you shouldn’t hurt the metal.
Do spark plugs improve acceleration?
Improper operation of spark plugs due to incomplete combustion can increase fuel consumption and greenhouse gas emissions.
Lack of proper acceleration is another symptom of defective car spark plugs.
This prevents the engine from responding to the accelerator pedal compression and trying to increase speed.
How does the car react with bad Spark Plugs?
As bad as a spark plug, it can produce big problems that include bad engine operation, slow circles, and even not starting the car.
