Finding the best ignition coil is something that you will not have to deal with often like other vehicles parts, but it is still important to know how to and what this vehicle part does. In simple terms, an ignition coil is a component that is responsible for providing the energy required for creating the spark that ignites fuel. 

The coil does this by basically acting as a step up transformer. It increases the voltage from the battery to thousands of volts, which are transferred to the spark plugs to ignite the fuel in the combustion chambers.

However, these coils come in different types and qualities but ultimately, the best one should help your engine achieve low emissions while providing a high power output.

This means that you need to be very cautious when selecting this product, and to help you do this, this article looks at some top ignition coils in the market and also provides a buying guide.

How to Buy the Best Ignition Coils

Ignition Coil Buying Guide

1. Compatibility

When it comes to ignition coils, compatibility is the biggest factor to consider. Each product is usually designed to fit in certain car engines.

The problem is usually in the engine design because car manufacturers construct their engines differently, having different fittings and slots with different shapes and sizes.

Therefore, each ignition coil set is usually meant for a particular car or cars that share a commonly designed engine. But, some like King Auto Parts DG508YELLOW have a wide compatibility as they can work for various vehicle models.

With this in mind, it is important to always check which car engine the product is made for so that you dot waste your money on something that won’t fit. 

2. Number of coils in the pack

In modern cars, each spark plug is usually connected to its own ignition coil. Therefore, if you have a V8 engine, you will need to change 8 ignition coils once they start failing.

This means that you should buy a pack that has at least 8 coils like Bravex Y1011-BX-UP or buy 8 packs for those that comes as single coil like Delphi GN10571.

Therefore, it is important to consider how many coils your car needs so that you can buy a pack with that exact number or more.

3. Accessories

Accessories are always an added plus. They give you something extra that makes the deal sweeter.

In the case of ignition coils, accessories usually come in the form of spark plugs because these coils function with the plugs to fire up the engine.

If you get an ignition coil that comes with such accessories like King Auto Parts DG508YELLOW, it should be worth considering and buying because this will allow you to change both parts, leaving you with a renewed firing system. The result of this would be a better performing engine.

The only important thing to note here is that you should compare the prices of the product without the accessories, with the accessories and the accessories alone. This will help you determine if the deal is good or not.

4. Brand 

Different companies are known for producing different quality products and the same applies to the production of ignition coils.

Brands such as Bosch are well known for producing high performance ignition coils for German cars. 

On the other hand, ​ENA, which is one of the best ignition coil brands, is well known for producing the coils for North American cars.

As you narrow it down to the best ignition coil for your car, it is important to consider such brands because they are well known for a good reason. Their products are of very high quality and are the best replacements that you can get.

5. Warranty

A warranty is important for many reasons. First, if the product has a manufacturer related defect, you simply have to invoke the warranty by informing the seller so as to begin the refunding or replacement process.

Without it, you might be in trouble after you make the purchase because anything can happen.

Another important thing to consider would the warranty duration. Some ignition coils have a 1-year warranty, which is good, while others have a lifetime warranty.

A product with a lifetime warranty is the best one to consider because it essentially means that your investment is protected up to the day it completes serving its purpose and requires a replacement.
