Top 10 Best Ignition Coils [2020]

Ignition coils are some of the most important parts of an engine. The role of an ignition coil is to draw voltage from a 12 volts car battery and amplify it into a higher voltage required by the spark plug to ignite the fuel and start the combustion process. Thus, it’s important to have a functional ignition coil at all times.

Just like other car parts, the ignition coil may fail over time. Once it starts failing, you’ll have trouble starting the engine or experience power loss. Your car can also stall in the middle of the road. In case you notice that the ignition coil is failing, you should have it checked for possible replacement.

If the ignition coil is found to be faulty, replace it to get your car on the road again. However, you need to get the right ignition coil for your car. With the right ignition coil, your car will start smoothly and the combustion process will be smooth.

It can be quite challenging to pick out the right coil from the many options available today. Luckily, we have made it easier for you.

Frequently Asked Questions

How does the ignition coil work?

The ignition coil draws voltage from the car battery. It amplifies the voltage to levels that are high enough for the spark plug to ignite the fuel and start the combustion process.

What are the signs of a failing ignition coil?

The signs of a failing or bad ignition coil include:

  • Problems starting the car- A faulty ignition coil will not supply enough voltage to the spark plug. Thus, fuel can’t be ignited and the engine won’t start.
  • The check engine light is on- In case the “check engine light” is on, then you should have the ignition checked for possible failure or other issues.
  • The engine is misfiring- A misfiring engine is a problem where the engine produces a coughing noise when trying to start a car. The problem is often associated with a failed coil.
  • Vibrations when idling- If your car is vibrating when idling, maybe at a stop sign, then it’s likely that the ignition coil is failing. The engine may also jerk and hesitate when accelerating due to a failing coil.
  • The engine stalls- If your car is stalling, it may stop and start abruptly. If it stalls completely, then it’s likely that the ignition coil has failed.
  • More fuel consumption- If your car is consuming more fuel for a similar distance than in the recent past, then it’s likely that the ignition coil is failing. In case the spark plugs are not receiving enough voltage, your car will consume more fuel.

How long does an ignition coil last?

A top-quality ignition coil should last approximately 100,000 miles.

Is it safe to drive with a failing ignition coil?

No, it’s not safe to drive with a failing coil. Your car will stall or even damage other parts. Thus, have the coil replaced soonest possible.

Can I replace an ignition coil by myself?

Yes, you can. You can easily learn how to replace it yourself by following online tutorials. However, if you’re not confident enough, have a mechanic replace it for you.

How much will it cost me to replace an ignition coil?

The cost will include the cost of buying the coil and the labor costs incurred if you’re going to hire a mechanic. The cost of an ignition coil differs depending on the brand and quality. Also, different mechanics often charge different rates. Thus, do a comparison depending on your budget without forgetting quality.

What causes the ignition coil to fail?

The main cause of failure is voltage overload, which often results from bad plug wires or bad spark plugs. The coil can also fail as a result of excessive vibration and heat.

Can I repair a bad ignition coil?

You can’t repair a bad ignition coil. You should replace it with a new one.

When should I replace the ignition coil?

Have it replaced as soon as it starts showing signs of failure.

Final Words

The ignition coil plays a major role in starting the car engine and ensuring that the combustion process runs smoothly. Thus, you should replace a faulty ignition coil soonest possible.

Replacing it will allow your car to start smoothly, regain its power, prevent further damages, and prevent it from stalling. Also, remember to consider important factors such as compatibility and quality.
