For every car owner, it’s essential to have a reliable sparking system for their vehicle. An ignition coil is one of the most important components, as it promotes an electric current in order to ignite fuel and get your engine started in no time. But with so many options out there, how do you choose between NGK vs. Denso when it comes to selecting the best one for your ride? In this blog post, we’ll provide a comprehensive review of its characteristics, as well as giving a comparison between both brands — allowing you to decide which type of ignition coil suits your needs most effectively! Read on if you want to ensure great-performing sparks each time you turn over your engine…
What is an Ignition Coil and How Does It Operate?
An ignition coil is an essential part of a car’s engine, converting the low voltage produced by a battery to the thousands of volts needed for spark plugs to ignite fuel. It works by taking the power from the battery and passing it through an inductor winding, then amplifying it with an iron core before sending it off as high-voltage electricity. This is done by using a high-voltage transformer and spark plug wires, which are connected to the ignition coil.
The current of the low voltage passes through the primary windings before its energy is increased again in the secondary windings. This increases the amount of volts produced and then finally sent off to the spark plugs for combustion. The amount of power created from this coil depends on its design and material used.
In addition to material type, the type of design used on an ignition coil can also affect its performance. A higher number of windings will create more voltage, but this may come at the cost of a shorter life span and wear out quicker. On the other hand, coils with fewer windings will offer better longevity and stability yet have lower electrical output. [1]
How Does Driving Performance Depend on Ignition Coils?
When you drive, it’s important to have a smooth and reliable engine performance. One factor influencing this is the ignition coil. Ignition coils act as an intermediary between the spark plug and the battery, transforming small currents into high-voltage sparks used to ignite the air/fuel mixture in your car’s cylinders. With poor quality ignition coils, you can experience irregularities like backfiring, engine stalling, and increased fuel consumption.
To get the best performance from your car, it is important to compare ignition coils from different brands and select one that offers superior quality and reliability. Many automotive parts stores offer a variety of options to choose from including standard OE replacement coils as well as ones built using higher-grade materials.
Typically, upgrades involve increased insulation on the windings for superior protection and longer life, as well as higher-quality components like stronger magnets for increased spark intensity and better fuel mileage. Additionally, some brands offer an array of performance options to address specific needs such as heavy load applications or those requiring a more precise spark output.
It is important to note that when it comes to ignition coils, you usually get what you pay for. Cheaper components are often prone to failure and can lead to expensive repairs down the road. Taking the time to compare brands will ensure that you get the best performance for your money. [2]

[3]
How to Choose an Ignition Coil?
When it comes to choosing the right ignition coil for your particular needs, there are several factors that should be considered. The main purpose of an ignition coil is to convert the low voltage from the battery into high voltage energy needed to spark the spark plugs. Therefore, when selecting a coil, it is important to consider its output power and design compatibility with your existing system.
The output power of the coil can vary, depending on the type and size of the engine. Generally, higher performance engines tend to require more powerful coils. It is also important to consider the physical size of the coil as some may not fit in certain cramped spaces or will require additional mounting hardware.
It is wise to invest in an ignition coil that has a good reputation for providing reliable performance. Doing some research online can help you determine which coils are best suited for your particular vehicle and needs. With the right selection, you can ensure that your car or truck will have reliable starts every time. [4]

Main Differences Between NGK Ignition Coils And Denso Ignition Coils
While both brands have been around for a long time and produce high-quality products, there are some key differences between them that you should be aware of before choosing an ignition coil brand for your vehicle.
The first main difference between the two brands is in the construction. NGK ignition coils are made with a copper core that provides superior conductivity compared to Denso’s aluminum core. This allows for more consistent and reliable performance, as well as improved fuel economy and engine life.
Furthermore, NGK also boasts superior insulation over Denso when it comes to their ignition coils. This means that the heat generated during operation is better absorbed and dispersed, resulting in a longer lasting coil and improved performance.
Another major difference in ignition coils is in the design of the connectors. NGK’s connectors are designed with a spring-loaded retainer clip that keeps them securely locked into place no matter how much vibration or shock may be encountered. Denso’s connectors, on the other hand, do not have this retainer clip and may become disconnected during operation.
Also, NGK ignition coils are also known to have a longer service life than their Denso counterparts. This is due to the superior construction of the components and insulation material used in their production. [7]
Is It Possible to Change Ignition Coils by Myself?
If you don’t have the right tools or experience with car repair, attempting this job yourself may end up costing you more than if you had gone to a professional. That said, there are some steps that you can take to change out an ignition coil without too much trouble.
To begin, you’ll need to disconnect the battery and remove the spark plug wires from the ignition coils. Once this is done, use a wrench or socket to unscrew the mounting nut that holds each coil in place. You may also need to loosen any bolts that are attached to the engine block as well. After all of these items are removed, the old ignition coil should be able to slide out relatively easily.
Next, you’ll need to install the new ignition coils and reconnect them to the spark plug wires. Once this is done, it’s important to ensure that each coil is securely fastened in place with its mounting nut. Make sure that there isn’t any excessive movement or gaps between the coil and the engine block, as this could cause problems down the road. [8]
Lastly, ensure to reconnect your vehicle’s battery before turning the ignition back on. This should ensure that your new ignition coils are working properly and ready for use. Whenever possible, it’s best to have a professional check out your work to make sure that everything is installed correctly.
