Ignition Coil Packs

Your ignition coil converts your battery voltage to higher voltages, creating the spark needed to start your engine. So, if you’ve noticed problems starting your car, a jerky ride, poor fuel economy or backfiring, it could be down to a failed ignition coil.

Catching and replacing a faulty ignition coil early can save you from bigger, more expensive exhaust problems down the line. Browse our range of reliable ignition coils and spark plugs to get you back on the road in no time.

What Does An Ignition Coil Do?

The ignition coil is a crucial component in any spark-ignition engine. It takes the low voltage from the car’s battery and boosts it to a much higher voltage; this voltage is then sent to the spark plugs. The spark plugs then ignite the fuel and air in the engine, starting the car.

What Are The Signs Of A Faulty Ignition Coil?

Since your ignition coil is so central to how your engine runs, when it starts to fail, you’ll usually notice. A faulty ignition coil can lead to unburned fuel entering your exhaust system and damaging your catalytic converter.

So, for your safety and to avoid a more serious, expensive problem down the line, you’ll need to replace your ignition coil as soon as you notice any of these signs of failure:

  • Engine misfires
  • Rough idling
  • Difficulty starting
  • Poor fuel economy
  • Backfiring
  • Illuminated engine warning light on your dashboard

FAQs

How Long Does An Ignition Coil Last?

Most ignition coils are built to last and have a lifespan of roughly 80,000 to 100,000 miles. They can fail at any time, so it’s still important to keep an eye out for any warning signs.

Can I Drive With A Bad Ignition Coil?

A faulty ignition coil means your car probably won’t be able to start. If you are still able to start your car, we recommend that you don’t drive as it’s unsafe and will damage your engine.

What Causes An Ignition Coil To Go Bad?

Several things can cause your ignition coil to become faulty; as it sits within your engine, the high temperatures and vibrations can wear it down overtime. Other failed ignition components, like spark plugs, can also put added strain on your ignition coil, causing it to give out.
