If you keep hearing the click-click-click of your ignition switch when you start your car but your engine doesn’t catch, it could be the time to check your ignition coil. That’s right — it’s one of the most essential parts in your engine and it could even be your problem.

What is an Ignition Coil?

The ignition coil is basically a wires-to-wireless transformer. It converts the 12-volt electricity from the battery to a high-powered electric current to spark a spark plug … a very small spark … which creates an explosion inside your engine to start it.

What Makes A Good Ignition Coil?

The good thing about spark plugs is that you can easily change them. If your ignition coil is bad, you can replace it with a new one and voila! It’s as easy as that. However, if you’re about to replace your ignition coil, you need to make sure that you’re getting the best one for your vehicle.

Here are the top 10 ignition coils on the market to help you make the right choice for your vehicle.

Bosch 0221504470 Ignition Coil

Check Price on Amazon

Pros:

  • Long life
  • Designed to work on other vehicles as well
  • Standard and direct models available

All Bosch Ignition Coils are designed and tested by creating a prototype before the last detail is perfected. A local Bosch testing center then runs each coil on a special dynamometer to ensure that every coil is capable of reaching its specified performance.

Most Bosch ignition coils are tested in the opposite way a vehicle would actually fire its ignition. That's because it would be hard (and cost-ineffective) to test every single on a vehicle. After firing, the coil's resistance is measured so that its performance can be compared to the baseline that was used for each one. Every ignition coil that sells has a sticker on it with a performance number. It lists a cold start number, a hot start number, and the peak number that is measured once a coil has been firing for a while. It also lists the elapsed time it took for the coil to reach the peak firing number.

Pros:

  • Plenty of Safety Features
  • Budget Friendly

The Giro Cinder is my top pick as it packs many safety features in a budget friendly helmet.

Giro’s decision to use in-mold polycarbonate for its shell allows for the addition of 26 massive Wind Tunnel vents with internal channels that route air over your head and out through the exhaust at the back of the helmet and keep your head amazingly cool.

Frequently Asked Questions (FAQ)

Is there a difference in ignition coils?

Yes there is. Both coils and points are responsible for getting most of the spark a vehicle needs, but they do so in a different way. Points sit between you car’s plug wires and the spark plug itself, while coils are located in cylinders near the spark plug. The spark travels through each ignition coil then through the plug wire to the spark plug—which is the hot part of the equation.

As you may have guessed, coils and points aren’t the same thing. But if you have no idea what a spark plug is, that’s okay; just know that this entire thing—spark plugs, points, and coils—is what makes your car work.

So why would you ever need to buy a new one?

Are ENA ignition coils any good?

Both ENA and Bosch have a strong reputation for manufacturing some of the best ignition coils on the market. ENA ignition coils are sealed and are known to have longer service life. When it comes to ignition coils, the quality really matters. You can’t just rely on the reputation of the brand; you need to seek actual customer reviews. Fortunately, it’s not difficult to spot actual reviews of ENA ignition coils. Most reviewers agree that ENA coils are both high quality and affordable.

Is it best to replace all ignition coils at once?

Since you’ve already decided to replace one ignition coil, it makes the most sense to replace them all at once. This promotes the integrity of the system and protects against excess current or a bad connection.

Sending too much current through your ignition coil can lead to pre-mature damage to your distributor cap. The distributor cap is attached to your crankshaft by a distributor shaft. If you send too much current through your ignition coil, the shaft can wear prematurely, making it impossible to accurately time the engine. This results in a miss-fire, stalling, hesitation, loss of power, and over all poor performance.

Damaging one of these components is considerably cheaper than replacing the entire ignition system. It is advised to replace your ignition components as a set if possible.

Do high performance ignition coils make a difference?

For most modded engines, high performance ignition coils are irreplaceable. In spite of the fact that not all types of engines require them, there are those that are irreplaceable. Most engines with performance mods often rely on these ignition coils to perform better. They are sometimes built to offer high performance to meet other mods, and this is why the upgrade is a must.

Conclusion

Safety should always be at the top of the list when looking for ignition coils. The recommendations we made are focused on three fundamental things: energy, power, and durability. These are the three most important factors that determine the safety of any car part, especially higher voltage parts such as ignition coils. While we hope that our recommended products offer you peace of mind, we do still encourage you to exercise caution when working with any car part.
