As an Amazon Associate, I earn from qualifying purchases.

The main difference between an Accel coil and Vs stock coil is the material they’re made of. Accel coils are made of copper, while stock coils are typically made of iron. This makes Accel coils more durable and better able to withstand high temperatures.

There are a lot of different modifications that can be done to a car. One popular modification is an aftermarket coil. There are several different types of coils available, but the most common is the Accel coil and the stock coil. In this blog post, we will compare the two and discuss the benefits of each.

What Is Accel Coil?

accel coil

An accel coil is a type of induction coil that is used to increase the amount of electricity that is produced. It does this by creating an increased magnetic field around the coil. This increased magnetic field will then cause more current to flow through the coil, which in turn will create more electricity. The accel coil is commonly used in high-voltage applications, such as power transmission and induction heating. It can also be used to create magnetic fields for purposes such as MRI imaging and particle accelerators.

Direct OE Fit

The Accel Ignition Coil is a direct OE fit for your vehicle. It is designed to deliver the high voltage needed by your ignition system to fire the spark plugs. The Coil features copper windings and an epoxy-filled interior for long-lasting performance. It also has a built-in resistor which reduces radio frequency interference.

Advanced Bobbin Technology

The Accel coil features advanced bobbin technology, which helps to improve the distribution of energy throughout the entire coil. This ensures that the spark will reach the spark plug more efficiently, providing a more powerful and consistent ignition. Additionally, the advanced bobbin technology keeps the coil cooler, reducing wear and extending its life.

Highly Specialized Silicone Magnetic Steel Cores

The Accel ignition coil is a highly specialized piece of equipment. It features a unique silicone magnetic steel core that helps to produce a strong and reliable spark. This core is surrounded by a high-temperature insulation material that prevents heat from building up, ensuring that the coil remains cool even under heavy use. Additionally, the coil features brass connectors that provide superior electrical conductivity and resistance to corrosion.

Optimum Winding

The Accel ignition coil features a patented Optimum winding, which ensures spark energy is distributed evenly across all the combustion chambers. This helps to create more complete and efficient combustion, resulting in improved horsepower, torque, and fuel economy. Additionally, the Accel coil is built with high-quality materials that are engineered to last under extreme temperatures and conditions.

What Is Stock Coil?

Stock Coil

A stock coil is a type of electrical coil that is often used in applicators and inductors. It consists of a number of turns of wire wound around a central former, usually made from ferrite or similar materials. The number of turns and the diameter of the coil are key factors in determining its inductance. Stock coils are typically manufactured with induction values ranging from 1uH to 4mH, though other values are also possible. Coils with more turns will have a higher inductance than those with fewer turns. Coils wound with thinner wire will also have a higher inductance than those wound with thicker wire. In general, the closer the turns are packed together, the higher the resulting inductance will be.

Chrome Crainster Coil

Stock ignition coils can be improved with the use of a chrome canister coil. This will add an extra spark to your engine, resulting in better performance and fuel economy. Additionally, this coil is designed to resist heat and corrosion, making it a long-lasting option for your vehicle.

Special Crimped

Stock ignition coils come with a special crimped connector to make installation quick and easy. Unlike aftermarket coils, stock ignition coils do not require any additional wiring or modification. Simply remove the old coil and replace it with the new one for an instant upgrade in performance.

Soldered Internal Connection

One feature of a good ignition coil is a soldered internal connection. This helps to ensure that the electrical current flows smoothly through the coil, creating a more powerful spark. A weak or intermittent spark can lead to engine misfiring and reduced performance.

Heavy Duty Alkyd Tower

The Stock Ignition coil is a heavy-duty black alkyd tower with high-quality construction. It includes plenty of docs that are helpful in its installation process. This product comes with great performance and impressive patterns. It can be considered one of the best replacement parts that you can find in the market today.

Accel Coil Vs Stock

Accel Ignition coil provides optimum winding

The optimum winding is one that provides the most current with the least amount of voltage drop. This will ensure that your ignition coil can generate enough spark energy to ignite the air/fuel mixture in the cylinders.

Stock Ignition Coil Ensures Positive Contracts

There are a few things you’ll want to look for when choosing a stock ignition coil. The most important is ensuring positive contracts – make sure the coil has sufficiently strong springs that will create a good electrical connection between the spark plug and the distributor cap.

Accel Ignition Coil Provides better performance

The best ignition coil for Accel is one that provides better performance, such as increased horsepower and torque. When looking for an ignition coil, it’s important to consider the make and model of your vehicle, as well as what you’re hoping to achieve with the upgrade.

Stock Ignition Coil Provides Flashover Protection

The best ignition coil for a stock car has flashover protection. This protection prevents the coil from overheating and makes it last longer. It is important to choose an ignition coil that is specifically designed for your car model.

High Thermal Conductivity

There are a few factors to consider when choosing the best ignition coil for your car. One important factor is the coil’s thermal conductivity. A coil with high thermal conductivity will be able to dissipate heat more effectively, preventing premature failure. Another factor to consider is the duty cycle of the coil. A coil with a higher duty cycle will be able to handle extended periods of operation without problems.

Stock Ignition Coil Provides High Energy Output

A stock ignition coil is a type of ignition coil that is used in many gasoline-powered vehicles. They are usually found on older model cars, and they provide a higher energy output than other types of coils.

Pros and Cons of Accel Ignition Coil


  • Faster rise time
  • Low resistance
  • High Capacity
  • Resist shock


  • Not provide installation instruction

Pros and Cons of Stock Ignition Coil


  • Excellent high performance
  • Improved throttle response
  • Maximum Voltage


  • A slight misfire engine issue can happen


Are Accel ignition coils any good?

The ACCEL coils are as good as the original ones. The engine does seem to be smoother at idle and more responsive when accelerating, thanks in part to their high-quality materials which will stay within specs longer than other products on today’s market! With this experience under its belt, it seems that they can create anything you need for your vehicle including performance parts like spark plugs or even fuel filters if needed.

Do high-performance coils make a difference?

With a high-performance ignition coil, you can expect to see an improvement in four important areas. First and foremost is the larger spark plug gap which results in a more robust initial flame kernel at the start-up of combustion; this leads to increased real-world engine torque.

Final Words

There are a few key differences between an Accel coil and a stock coil. Accel coils are generally manufactured with higher-quality materials and have more precise specifications. This results in better performance, increased durability, and improved fuel economy. In addition, Accel coils often have resistance values that are specifically tailored to improve engine performance.

The stock coil is a good choice for most applications, but the accel coil can provide a number of benefits for certain situations. If you are looking to improve your car’s performance, consider upgrading to the accel coil. We can help you find the perfect coil for your automobile and get it installed quickly and easily.
