Know about the heart of your engine


When talking about spark plugs, there are majority of vehicle owners who have no clue about their spark plugs. They aren’t even aware of the fact that it is the spark plug which gets their car going. Most people don’t even think about the maintenance of these small parts, unaware that they play an incredibly important role in the functioning of your car.

It is true that spark plugs which do not work properly can damage your car to the extent that it won’t even start. Thus, you need to understand that spark plug is a very important component in the functionality of your vehicle.

Function of spark plugs

The engine of your vehicle is a pretty remarkable machine, designed in such a unique manner that it turns the energy source into the actual movement. And it is true that the engine doesn’t do that all alone. To turn the fuel from a source of potential energy to a source of kinetic energy, your engine finds a way to release it through combustion process.

To make this happen, your spark plugs supply the spark which helps in the ignition of the air/fuel mixture, and creates the explosion which makes your engine produce the power. These small plugs create an arc of electricity across the leads. The spark plugs and the electrical and timing equipment are part of the engine’s ignition system.
Generally, spark plugs are made from extremely durable material and are capable of withstanding a number of explosions before wearing out or being replaced. But it is also a true fact that over time, with these explosions spark plugs tend to become weaker with time. In such a moment, you need to replace your spark plugs.

Changing your spark plugs
Many people aren’t aware as to when should they change the spark plugs. There are some factors that you tend to experience which define whether your spark plugs need to be changed or not. You must be aware that spark plug has a lifespan and will wear out after that. Be sure to consult a mechanic or owner’s manual if you feel your spark plug has worn out.
Selecting New Spark Plugs
While selecting new spark plugs, you must make sure that you select the ones which are most suitable with your vehicle. Choosing the wrong spark plugs for your vehicle will affect your vehicle in a number of ways. Never compromise in the matter of spark plugs.

Tips on super performance spark plug maintenance


The engine of your vehicle requires super performance spark plug maintenance to run on its optimal condition. It is this tiny component which brings the electric current to the combustion chamber and powers your engine. One must take care of their spark plug and have them regularly changed to avoid any ignition problems.
There are times when dark black residue builds up on your vehicle’s spark plug due to a number of combustion. This must be taken utmost care of as this will then have certain affects on the performance of your engine. Given below are two tips you can follow for easily tackling super performance spark plug maintenance:

1. Engine Inspection Routine: By regularly inspecting your engine, you can look after your car properly. For that you need to check your spark plugs on regular basis (at-least as per the recommendation of service manual for better result). This gives you an opportunity to inspect the status of other components as well, such as the cabin air filer, brakes, fuel filter, charging system and the starting system.
Undergoing a regular engine check-up is a vital part of the super performance spark plug maintenance. It is never recommended to push your faulty spark plugs at the edge of its last spark. It is advised to check the spark plug beforehand and replace prior to engine failure which might eventually lead to catalytic converter damage.

2. Installing New Spark Plugs Regularly: Every spark plug has its own life expectancy. Some might wear out early and some might wear out a bit late. When you start to encounter rough idle, misfire, high fuel consumption or any other signs of a faulty spark plug, it is advised to visit the mechanic as soon as possible. You should never postpone replacing your spark plugs as delaying it would make your engine jerk hastily.

Keep the spark ignited to boost your engine’s performance


Everybody takes extra care of their car. For maintaining their car, they take it for check-ups to the mechanic, to make sure if the car and all its parts are in good condition or not. During the check, you check whether the engine is still clean, is the oil fine or does it need to be changed and are all the parts functioning properly or not. People usually don’t give much attention to the smallest things, and sometimes that is what has the problem.
While getting a check for all the parts of your engine, you also get a check whether the spark plug is in good condition or not. Perhaps, spark plugs are usually not the first things people get attention towards when they are checking on their vehicle’s condition. Some vehicle owners on the other hand aren’t even familiar of these small parts of their car.
However, you might have underestimated the importance of these small parts, though they are the heart of the engine. They play an important role in your entire vehicle’s performance.

Losing the Spark – What is the purpose of a spark plug in the engine exactly? Initially, spark plugs are used to ignite the air and fuel mixture in your car. It is the spark plug which transmits the electrical energy which then ignites the gasoline and air mixture inside the combustion chamber.
There are many signs which you tend to notice indicating that your spark plug is faulty and needs to be changed.

Reigniting That Spark – With time, your spark plugs tend to worsen and require more voltage to bridge the gap between the center and ground electrodes. Worn out spark plugs tend to have an adverse effect on the engine performance and this therefore also affects the performance of your car.To avoid this, you must make sure that your spark plug is in excellent condition.
Changing your spark plugs timely assures your car’s top efficiency. Along with this, investing in high-grade car parts will also boost your car’s engine performance. So make sure your car never loses that spark!

Why do Spark plugs become loose?


Spark plugs though small are one of the most essential part of every engine. The good health of your car depends solely on this very small but crucial factor. The heart of your vehicle needs to keep up the pace on the roads.

The Reasons spark plugs become loose are:

1. Low maintenance of the engine and spark plug – There are times when you would think that the problem might due to something big, but sometimes it’s because of the smallest of things. The spark plugs need a thorough check from time to time. You need to check for loose spark plugs as they affect the ignition.

2. Less clean threads – Not cleaning the threads quite often can lead to bad alignment of the spark plug, leading to spark plugs popping out of the engine.

3. Over tightening the spark plugs – Seeing a loose spark plug you might just want to grab the torque and set the plug right in place, but it is advisable you do not do it. It is better to visit the service station and get it tightened by the service station members.

4. Bad thermal character – A bad thermal character of your vehicle can badly affect the spark plug. Changing thermal character heats up the engine and the spark plug, which in turn gives us some loose spark plugs on the engine.

If the spark plugs are not checked from time to time, if the regular services are not done with, cleaned or changed according to need, then it will give you a very rough ride on your pockets as well as the road.

How to replace your spark plugs?


Wondering why your vehicle is having troubles while starting? Your gut instinct may say it’s the battery. However, that might not always be the case. There might be another culprit to blame.
Spark plugs create a spark of electricity that ignites fuel and drives a car’s pistons, ultimately starting the car. With regular wear and tear, spark plugs tend to burn out
Let’s see how we can replace spark plugs.



  1. Gather all the tools and wires that you may need for the procedure. It is a good practice to disconnect the positive terminal on your battery when working on anything electrical.
  2. Thoroughly clean the area around your spark plugs. You can use compressed air to blow the area clean, or a cleaner/degreaser spray and shop towels to loosen and remove any grime around the spark plug. Be sure to wear eye protection while doing so.
  3. Now is the time to start the actual replacement process. Keep everything orderly by removing a single spark plug wire from one spark plug at a time. This prevents reconnecting the wrong wire to the wrong plug when it’s time to button everything back up.
  4. Fit the necessary combination of extensions and swivels to the spark-plug socket to comfortably fit the tool to the spark plug.
  5. Once the spark plug is out, take the new spark plug and use the spark plug gap tool to check that there is a proper gap between the outer (hook-shaped) ground electrode and the center electrode. If any adjustment is needed, gently open or close the gap until the tool just fits at the correct gap.
  6. Now, carefully insert the plug into the open hole by hand. Tighten the plug down with the spark plug socket.
  7. With the spark plug securely re-installed, reattach the plug wire by twisting slightly as you push the boot back down onto the exposed tip of the plug until you hear and feel a firm click.

Don’t forget to mark down the vehicle’s current mileage in your maintenance notebook, so you’ll know when you need to change your spark plugs again. And you’re done!

NGK-BlogWhen you detect oil on your spark plugs, you must be aware of the fact that it is a bad news for your engine. But you don’t have to panic on the situation, as it might not be as bad as you think.


There could me multiple reasons why oil can find its way on the spark plug. One of the cause can be by leaking valve cover or spark plug o-ring. As spark plug is the heart of the engine, you need to take extra care for the same. Given below are the causes of oil covered spark plugs and tips on how to fix it.
Causes of Oil On Spark Plug
There might be several causes of how and why your spark plug is covered in oil. Some of those are listed below:

  1. Valve Cover Gaskets: Valve cover gaskets keep the oil on the cylinder heads and away from the rest of the engine. Due to high temperatures in the engine environment, these gaskets tend to wear, allowing the oil leakages. This dripping oil then reaches the spark plugs and causes the oil on the plug condition.
  1. Spark Plug O-Ring: This ring is the seal which is located inside of the valve cover. With excessive amount of heat, this seal tends to degrade over time and makes the oil reach the spark plug.
  1. Defective or Worn Valves Guides: Another cause for oil covered spark plugs is the excessive wearing of the valve guides. The constant up and down movement of the valves pump the oil into the combustion chamber creating a direct consequence oil on the spark plugs.
  1. Faulty head-gasket: The engine oil flows in a pressure all its way up to the heads through the lines and galleries of the lubrication system. With a faulty head gasket, the oil enters the cooling system and/or t he engine cylinder.

Fixing Oil On Spark Plugs
One of the most common causes of detecting oil on spark plugs is the damaged or leaking valve cover gasket or the spark plug O-ring. To get through this situation, you must change them. This can be done by referring to the owner’s manual and if you’re not sure of how to change them, head to the nearest mechanic to get it changed.

Importance of spark plug gap


Our love for our vehicles might last forever, but at times they cannot even take the smallest of the problems like a spark plug gap.

We might overlook the spark plug gap during our routine checks of the engine but an incorrect spark plug gap might adversely affect the vehicles performance.Here are a few important points you cannot miss out about the spark plugs and surely have to mind the gap this time.

1. Affects Engine performance – If the gap between the electrodes is not as per the recommendation than it will affect the engines performance. If the gap is not set right then it might result incomplete combustion of the air fuel mix. 

2. Affects Voltage – The spark plug gap also affects the voltage use on your vehicle. More the gap, more is the voltage required to start the spark on the plug. If the gap is too small it may create a very small spark that will be insufficient to start the engine.

3. Affects fuel efficiency – Gap in the spark plug not only affects the performance but also the fuel efficiency, obviously you might not want to give extra money on fuel to fill the gap.

4. Optimal gap set for a perfect running vehicle – Some of the manufacturers have set an optimal gap set to follow on their vehicles. So it is important to follow it and go by the rules for better performance of the vehicle.

A spark plug gap is not a tangible part of the engine system, but if the gap on the spark plug is incorrect then it can affect adversely on its performance. It is advisable not to play around the gap as it might result in cylinder misfire, no combustion and cause carbon fouling on spark plugs. A fouled spark plug will give you a very rough ride all the way.

3Things to keep in mind for proper care of Spark Plugs

NGK-BlogSpark plugs are known to be the mighty little workers, which are the hardest working part in a vehicle next to the tires,because of them, the car starts. They are one of the important elements that are required to start a car. They are continuously working until the key shuts off. They are the smallest part in the vehicle, yet several key functions are affected from it (idling, accelerati0n, power, fuel consumption).
The life of a spark plug is really important and this somewhere depends on the way and style of your driving. If you’re driving at a higher speed than usual, then there are chances that the gap would increase faster than driving at a local speed.
Caring for your spark plug is as important as caring for your car or bike. Just like you change your tyres frequently, you must also check on the condition of your spark plug and take the necessary action required as per its condition. Caring for your spark plug has several reasons, as it is of prime importance in the functioning of your vehicle.
Here are some ways on how to care for your spark plug:
1. The first step to spark plug care is to know when and how to clean it. For this, you have to locate and remove it from the engine. Once it is done, you have to look at the rings on the plug’s insulator part. If the insulator is covered in layers of dust-trapped oil or soot, this indicates that your spark plug is in the need to be cleaned. To clean the same, you require petrol or kerosene and a small brush.

2. You can easily detect the condition of your engine with the help of spark plug. If the engine of your vehicle is running too hot for spark plug, then the insulator will be glazed and covered by burn marks. To make sure that your spark plug and your engine is functioning smoothly, you must follow the heat range that is specified by the manufacturer.

3. Another factor of prime importance that needs to kept in mind while cleaning or replacing it is the spark plug gap. As different model of your vehicle requires a different gap requirement, you must refer to the manual in such case to avoid any sort of problems further.
At times when you are at a road trip or going to a place, your vehicle might break down. This knowledge of how cleaning and replacing spark plug will come handy to your rescue. If you are up-to-date with your vehicle’s conditions, you can go ahead confidently with the same.

Glow plugs vs Spark plugs

NGK-BlogGlow plugs and spark plugs are considered to be similar despite they have several differences between them. Talking about the similarities, all engine combustion require three things, i.e. the fuel, air and heat or a source of ignition. Both glow plugs and spark plugs work as a source of ignition during the combustion of the engine. The main difference between the two is just the type of engine they are actually found in. As we all know, spark plugs are found only in gasoline engines and glow plugs are found in diesel ones.
With the difference in the engine type they are found, there also comes a slight difference in the functionality of the same. Let us understand how both plugs differ from each other.

Spark Plugs
A spark plug is known to be the essential part of your ignition, as your vehicle won’t start without it. Technically, it is known as the electrical component which is placed in the cylinder head of the engine. At this place, it receives a high-voltage from the ignition coil. A spark plug runs continuously to make sure that your engine keeps on running. In a gasoline car, the working of the engine is quite different. In this, the fuel is mixed with the intake air inside the throttle body before the same being injected into the combustion chamber. With this, the spark plug generally receives a high-voltage charge from the ignition coil, creating a spark and igniting the air-fuel mixture.

Glow Plugs
A glow plug is known as an electrical heating device which is situated in each cylinder of the diesel engine. This ensures a reliable start in all the weather conditions especially in cold weather. A glow plug is required only during the ignition process, unlike a spark plug which functions continuously while you’re driving. It works by electrifying the heating element present in the engine, so it heats up and helps to reach the Self Ignition Temperature of diesel in fraction of seconds. In diesel engines the fuel is injected directly in to the combustion chamber where it mixes with the compressed air, and starts the combustion, even when the engine is cold.
