Throttle Response Higher Lower
Performance Higher Lower


What Are the Differences Between Ignition Coil and Stock Coil?

The main difference between performance ignition coils and stock coils is that performance ignition coils have a higher voltage. Stock coils are only designed to offer sufficient volts for the engine ignition, while performance ignition coils can improve the performance of the vehicle’s engine.

They differ mainly in the amount of voltage they produce, with the performance coils being able to produce higher voltage levels than stock coils. Therefore, if you’re after improving the performance of your engine, torque, and throttle response, the best option for you is the performance ignition coils.

– Overall Comparison

Both coils are designed for the same purpose, but one is a lot better than the other, especially in terms of improving driving experience and vehicle performance. Voltage potential is their key distinguishing feature. With a stock ignition coil, you will only get enough volts and a spark to facilitate conduction. High-performance coils, on the other hand, are designed to deliver higher volts with much ease.

There’s no exact answer to which of the two coils is the best. However, what’s certain is that high-performance coils offer more benefits than stock coils. The design of high-performance coils is such that they can easily resist greater voltage and high temperature. They are mostly made from heat-resistant materials to ensure that they don’t get easily damaged and function effectively within high-performance engines.

Drivers looking to improve throttle response, power, and have an extra boost in difficult terrains would benefit from performance coils rather than stock coils. This includes drivers that frequently drive up an incline or drivers participating in a racing event.

What Are Performance Ignition Coils Features and Benefits?

Performance ignition coils key features and benefits include their ability to improve engine performance. They are mostly attached to the spark plugs, where they create higher voltage than stock ignition coils. Performance coils are an option to consider if you want to improve your engine performance.


The need to upgrade ignition coils is mostly higher in drivers of high-performance vehicles. This is because the coils help create more power, thereby improving the vehicle’s performance. With that, they can easily drive through the wind, uphill, or even with tires on low pressure.

Performance Ignition Coils

These coils can also create extra power due to the larger space between the coil and the spark plug. That’s not the case with stock coil, as the space is smaller. The larger space is an indication that the coil can create a stronger flame for combustion, which will further increase the voltage level of the vehicle.

Dragon Fire, Yoshi Motors, and ACCEL are three top companies known for selling these coils. If you’re considering getting performance coils, you should understand that they don’t work in every vehicle. There are many advantages of using performance coils, and they include the following:

– Higher Voltage

The main benefit of using performance coils, as mentioned earlier, is the ability to provide higher voltage with ease. Today, you’ll find some of these coils on the market with the ability to produce up to 100,000 volts. This high voltage can move across the large gap within the spark plug to produce a stronger combustion flame to further enhance the performance and efficiency of your engine.

– Quicker Spark

In addition to creating stronger combustion flame, performance coils also provide a quicker spark. A combination of quicker spark and combustion flame allows the engine to operate with higher responsiveness, and your vehicle will be less likely to misfire.

– Better Throttle Response

Another benefit of the performance coils is that they will boost your throttle. Unlike the stock alternatives, these coils are designed to provide more power to enhance combustion and further improve the response of your throttle.

– Higher Power for Difficult Driving Conditions

With the performance coils, you can rest assured that your vehicle will have more power to drive through difficult terrains. This is further enhanced by the higher voltage potential of the coils. Whether you are driving into strong winds, on low tire pressure, or uphill, with performance coils, you have nothing to worry about.

In addition to these benefits, there are a few disadvantages associated with these coils, and it’s important to know these disadvantages. They include the following:

  • Poor-quality performance coils are cheaply and badly made, and these types of coils have a higher chance of causing serious damage. Installing this type of coil will cause your vehicle to misfire frequently.
  • Performance coils are generally more expensive than stock coils, and the cost will be higher if you cannot install them yourself.

What Are Stock Coils Features and Benefits?

Stock coils key features and benefits include their ability to create enough volts to enhance engine ignition. They are the preferred option for modern cars, especially when the factory-fitted coils need replacement. Stock coils are also designed to last longer, especially with proper maintenance.

Stock Coils Features

Generally, ignition coils are purposefully designed and built to work with certain car models and makes. In some cases, you’ll find a single coil per cylinder, but there are some cars that only have one ignition coil to enhance combustion in all cylinders. Also, modern vehicles utilize ECU to receive high voltage from the coils, while distributors do this in older vehicles.

As mentioned earlier, stock coils are designed to last long, and you can use them for up to 100,000 miles. With this coil, you won’t need to worry about spending so much on getting a replacement.

However, even though they offer a long lifespan, it’s important to note that they are also likely to fail sooner than you expect. The stock ignition coil is the best option to get, especially if you’re not after boosting the performance of your vehicle. You have many benefits to enjoy from these coils, and this includes the following:

– Purpose-Built

Every stock coil is designed to work for a particular car make and model. The coil is also designed to offer the right amount of voltage required for combustion. Since all cars don’t have the same engines, it’s important to ensure that you use the right coil for your vehicle if you want it to provide the exact amount of voltage for combustion.

– Easy to Replace

The process of replacing stock coils is an easy one, and if you’re installing OEM coils, you only need to find the right parts number. To get this number, you only need to check your vehicle manufacturer’s website, and search for the model, make, trim, and year.

You can also use the VIN of your car to know the part numbers you need. After getting the right number, you can easily buy the coil through a dealership or online.

– High Quality

Stock coils are generally made of high quality, which is why they last long. If you’re buying an OEM part, you can rest assured that it will offer high performance and quality.

– Spart Plug Boots Included

Stock coils are designed with spark plug boots, and this helps the coil to stay firm on the spark plug. Properly fitted coils guarantee that all components will work at their highest capacity. Another benefit of the secure connection is that it prevents rain, contaminants and debris from causing damage to the spark plugs.

In addition to these benefits, there are some disadvantages to note, and they include the following:

  • Stock coils can only offer the voltage required for the sufficient performance of the vehicle. They are designed to only produce between 40,000 to 45,000 volts, and if you want something higher, they may not be the right option for you.
  • Higher voltage is required for more efficiency and quicker response. You don’t get this with stock coils because they only offer sufficient voltage for your vehicle to perform. Stock coils will disappoint you if you’re after improved throttle response.

What Are the Advantages of Upgrading to a Performance Ignition Coil versus Sticking with the Stock Ignition Coil?

Upgrading to a performance ignition coil offers numerous advantages compared to sticking with the stock ignition coil. The functions and benefits of car radiator and condenser are well-known, but let’s focus on ignition coils. A performance coil provides a stronger spark, resulting in improved fuel combustion and enhanced overall engine performance. It also ensures reliable ignition, better throttle response, and increased fuel efficiency. Embracing a performance ignition coil can transform your driving experience and maximize your vehicle’s potential.


Ignition coils are present in every car engine, and they are mostly attached to the spark plugs. They are designed to provide the volts needed for combustion. Today, you’ll find stock coils on most vehicles, but you can replace them with aftermarket performance coils. In this article, we have highlighted the differences between both coils, as well as their benefits, so that you can choose between the two.

Performance ignition coils are your best bet, but before choosing performance coils, it’s important to ensure that your vehicle is a performance vehicle; otherwise, you won’t notice any significant difference.
