Spark An Electrifying Performance With VEVOR's Ignition Coils

The heartbeat of many machines lies in their ignition system, with one key player powering the system - the ignition coil. Ignition coils stand as the mainstay at the core of the internal combustion engine, transforming the battery’s voltage into sparks that bring life to the engine. 

Engine coils are predominantly associated with automobiles. There is no wonder this is so; the automotive ignition coil market is valued at over USD 10 billion in 2023. The ignition system market is about 5% to 7% of the parent automotive industry

With spark plug coils being a significant player in automotive with a good share in other engines, VEVOR’s active participation is a given!

Why Do You Need Ignition Coils?

Ignition coils are necessary for igniting and maintaining the spark needed for the combustion process in a combustion engine. They ensure the engine runs smoothly, guaranteeing optimal performance. The function of an ignition coil includes:

Spark Generation

The primary function of an ignition coil pack is to generate the spark that the engine needs for internal combustion, i.e., air-fuel mixture in the engine cylinders. The ignition starts the process, powering up the engine. 

Efficient Combustion

Not only does a spark plug coil start a vehicle and ignite the combustion process, but it also powers and maintains it for the efficient running of the engine. It ensures solid and consistent sparks in the spark plug. This, in turn, maximizes performance and fuel efficiency. 

Engine Performance

Coils ignition maintains an engine’s power output and overall performance. Steadily ensuring adequate combustion, they help engines function optimally without mishaps. A good ignition coil reduces instances of misfires and rough idling, ensuring that the engine lasts long. 

Maintenance And Replacement

Many things can go wrong with an engine. However, little maintenance like the ones done on the coil pack can help prevent greater mishaps. Ignition coils don’t stay forever. They can wear out due to use, heat, and vibrations, among others.

Regular checking, maintenance, and replacement of coil packs can help save the life of an engine. Also, you can detect other problems while maintaining ignition coils, pointing them to other problems. 

Different Types Of Ignition Coils

There are various types of ignition coils. These spark plug coils are differentiated based on the winding and cooling. They all have different features, offering various advantages. 

Oil-Filled Ignition Coils

They are the traditional ignition coil with primary and secondary windings around an iron ore. They are usually heavier than the newer models but are also more reliable. They are usually immersed in oil for insulation and cooling. 

Epoxy-Filled Ignition Coil

This design offers better protection against moisture as it uses epoxy resin to encapsulate the winding and core. They are more compact and lighter than the oil-filled ignition, and they are more resistant to vibration and corrosion, making them more suitable for harsh weather. 

Performance Coils

High-performance ignition coils are somehow personalized. They use specialized materials to deliver more robust and more persistent sparks. These coils use high-quality materials for their cores and windings, making them better and more durable. 

Electronic Ignition Coils

Some modern vehicles have placed ignition powering on their electronic system. Using the engine’s control unit, they offer more precise and timed sparks. These coils are more advanced and reliable. 

Are Ignition Coils Only For Automobiles?

No, ignition coils are not only for mobiles. Although it is no news that the mobile industry takes the lion's share in using ignition coils, other combustion engines also enjoy the spark an infinity coil brings. Other applications of ignition coils include the following below. 


Some generators rely on internal combustion engines. These include small generators and some industrial generators. These generators use ignition coils to generate the high-voltage spark the ignition engine needs to ignite the air-fuel mixture for proper functioning. 

Boats And Marine Engines

Many boats and marine engines have internal combustion engines. These engines use ignition coils to function correctly. 

Other Small Engines

Many small engines, ranging from the ones we use at home, like lawnmowers, to industrial ones, like chainsaws, have an internal combustion engine. These engines use ignition coils to generate the spark they need to function. 

Why Choose VEVOR?

Having good ignition coils is not an option. It is a compulsion. Therefore, there is no way to reduce the quality of an ignition coil you use for your engine. In other words, your machine and vehicle’s combustion engine needs VEVOR’s ignition coil!

VEVOR’s ignition coils have been carefully engineered to outdo the conventional standard, intensifying the spark energy that drives the engine. With cutting-edge technology used in the design, VEVOR’s ignition coils ensure lasting and intensified spark. 

Furthermore, our years of proven reliability are again proven by the resilience and adaptability of VEVOR’s spark coils. Proving our mette, VEVOR allows you to test the spark plugs with designated tools before purchase and offers various after-purchase supports. 

FAQs About Ignition Coils

What are the signs of a failing ignition?

Common signs of failing ignition include poor fuel efficiency, rough idling, difficulty starting the vehicle, and engine misfires. Also, a failing ignition can sometimes cause the illumination of the check lights on the dashboard.

Can I test an ignition coil before purchase?

Yes, you can test an ignition coil before purchase. You can use a multimeter to measure the resistance, checking if the coil works perfectly. Also, the multimeter can check for any shorts or irregularities, ensuring you buy only the best coil. Furthermore, automotive shops have specialized testing equipment for ignition coils that can give you more comprehensive answers about them. 

Can a bad ignition coil cause other damages?

Yes, a bad ignition coil can cause other problems. For instance, a bad ignition coil can cause a misfire, which in turn causes damage to other engine components like the oxygen sensor or catalytic converter.

Do all engines use the same ignition coils?

No, there are different types of ignition coils to serve the various engines available. These varieties have different features, making them suitable for variable operations. Therefore, ensure that you learn about ignition coils and choose the one that best suits your engine.
