How did we estimate these prices?

Jerry's experts researched and collected data from 2500+ real repair shops in all 50 states in the US, including everything from the total cost of repair services to the hourly labor cost for mechanic labor in each shop. We combined that data with our expert database of hundreds of real repair jobs, thousands of real cars, millions of real car part prices in order to best estimate the cost of each repair service. Our labor cost estimate is calculated by taking the average hourly labor rate for a certified mechanic in the US, times the number of hours it takes on average to complete a repair. We recommend you compare your local shops with Jerry and contact those shops directly to get final pricing for your vehicle.

What parts do you need for an ignition coil replacement?

There are three main types of ignition systems. From oldest to newest, they are the conventional (or “contact breaker” or “breaker point”) ignition system, the electronic ignition system, and the distributorless ignition system. All three use ignition coils.
Here are some of the other parts they have in common:
  1. Ignition coils ($15-$910) are a staple of all three ignition systems. They transform the 12-volt current of the car battery into 60-120,000 volts of raw power. Distributors or distributor caps use either breaker points or pickup coils to time the bursts of electricity it sends to the spark plugs.
  2. Ignition switches
    ($5-$2,800) are found in conventional and electronic ignition systems. The switch completes the circuit and fires up the engine when you turn the key or push the ignition switch. Hitting the ignition switch again will interrupt the circuit and shut down the engine.
  3. Car batteries
    ($90-$700) are found in all three ignition systems. They supply the ignition coils with a low-voltage current once the circuit is completed.
  4. Ignition cables, or spark plug wires
    , ($4-$805) are present in conventional and electronic ignition systems. They pass the voltage created by the ignition coils and timed by the distributor to the spark plugs.
  5. Spark plugs
    ($2-$65) are essential to all three ignition systems. They shoot a high-voltage bolt of power across a small gap in each of your vehicle engine’s cylinders, igniting the mixture of air and fuel inside at just the right time. These electrical explosions bring your car’s engine to life like a mechanical Frankenstein.
Keep in mind: Restoring your car to life might require new ignition coils, as well as replacement spark plugs, spark plug wires, or a fresh ignition switch.
You can buy all the parts you need at auto part stores such as AutoZone or NAPA Auto Parts. You could also purchase them online from websites such as Amazon and eBay. 
Some popular brands of ignition switches are Standard Motor Products, ACDelco, and Dorman. For car batteries, Optima, ACDelco and DieHard are reputable brands. When shopping for an ignition control module, you may want to consider ACDelco, Standard Motor Products and Delphi. Bosch, Delphi and ACDelco are recommended ignition coil brands, and NGK Denso and ACDelco are recommended ignition cable/spark plug wire brands. NGK, Denso and Bosch are popular spark plug brands. The correct parts for your vehicle depend on the type of vehicle you drive. Be sure to consult your owner’s manual to ensure you’re purchasing the proper parts. 
You can buy replacement parts at automotive body shops, parts shops, dealerships, or online stores like Autozone or Amazon. If you prefer OEM parts, you can also try your vehicle manufacturer’s official website. Check your owner’s manual for any crucial specifications so you don’t buy the wrong part.

Original Equipment Manufacturer (OEM) parts cost much more than aftermarket parts but often include better warranties. For example, if a certified Toyota mechanic installs a genuine ignition coil in your car, you’ll get a 24-month/25,000-mile warranty. The average cost of parts is even higher for luxury makes like Audi or Mercedes-Benz. However, an aftermarket ignition coil pack will typically cost less and perform the same basic function.

How do mechanics replace ignition coils?

An ignition coil replacement is a simple service requiring a basic knowledge of ignition systems, little equipment, and plenty of caution. Take your car to the garage and the mechanic will:
  1. Disconnect the battery and allow the car to cool.
  2. Access the ignition coils by unsticking components and removing other parts as needed.
  3. Disconnect the wiring around the ignition coils and clean the connectors.
  4. Test the ignition coils with a multimeter or voltmeter to confirm malfunction.
  5. Replace the faulty ignition coil(s) and reconnect the wiring.
  6. Replace all parts and battery cables, then test the car.

Is it okay to drive with a failed ignition coil?

Ignition coils are an integral part of your car’s ignition and powertrain systems. Depending on the severity of the problem, your ability to drive may be impacted by:
  • A car that won’t start: If the ignition coils fail to fire up the engine, you won’t be going anywhere. Don’t let it be; an inactive car can easily get stuck in place.
  • Engine misfires: Without any electricity, any spark plugs connected to a bad ignition coil won’t fire, or will misfire. Besides a rough ride, you risk engine damage the longer the situation continues.
  • A faulty catalytic converter: If the air-fuel mixture in the engine cylinders doesn’t get ignited, where does it go? Well, it follows the path of the exhaust to the catalytic converter. Needless to say, the converter isn’t equipped to handle raw gasoline, and it could be damaged the longer you neglect a bad ignition coil. 

What is an ignition coil replacement?

An ignition coil replacement services the mini transformers inside your car that convert the low voltage of the car battery into a powerful enough spark to ignite the fuel in the engine’s combustion chamber. Ignition coils sit on top of the spark plugs in the standard coil-on-plug system that’s common in modern cars. They’re sold pre-assembled and in individual and multiple packs. 

What are the symptoms of a bad ignition coil?

In the absence of clear damage, it can be hard to determine whether your ignition coils are failing or not. Here are some warning signs to watch for:
  1. It’s been a while since you last replaced the ignition coils: Ignition coils should be replaced (or at least inspected) every 80,000 to 100,000 miles.
  2. Engine misfires, rough idling, unexplained vibrations, and sudden loss of power: If your ignition coils aren’t working, your engine cylinders won’t fire correctly or at all. This can produce unbalanced shaking, knocking, and stalling.
  3. Poor gas mileage: Reduced fuel efficiency goes hand in hand with a misfiring engine.
  4. Increased emissions: Ignition coil failure causes the unburned fuel in your engine cylinders to pass out the butt of your car and make the air stinky.
  5. A check engine light: The check engine light indicates a multitude of errors, but an OBD code reader (or a mechanic) can tell you if it relates to the ignition coils.
  6. Trouble starting the car: Without the vital spark provided by the ignition coils, your car might not start at all.
Key Takeaway If your car engine runs poorly and misfires, you could have an ignition coil problem.

How long do ignition coils typically last?

Ignition coils typically last 80,000 to 100,000 miles. Often, malfunctions and wear in other parts of the car cause ignition coils to fail. For example, if your ballast resistor breaks, your ignition coils might fry under the resulting power surge. Loose ignition cables and gaps can cause your coils to compensate for ever-larger doses of electricity. And finally, a lack of general maintenance could cause air, moisture, and dust to enter and corrode the coils.

Is an ignition coil easy to fix?

Ignition coils are usually easy to access and simple to replace, making them a great DIY job. However, as with services concerning your car’s electronics, you need to be careful about handling wires and preventing shocks. Try and find a detailed repair manual or instructional video before you begin, and remember your protective equipment.

FAQs

It’s good practice to replace all the ignition coils at once because, barring any unusual damage, they usually wear out at the same time. Asking a mechanic to replace several parts at once is cheaper than making multiple visits to the garage.
Unless your ignition coils are also failing, it’s not necessary to replace them and the spark plugs. Their lifespans won’t necessarily line up with those of your ignition coils. Copper and nickel spark plugs can last as little as 30,000 miles, while platinum and iridium parts may extend to 150,000 miles or more.
No, spark plugs and ignition coils aren’t the same thing. They look different and aren’t interchangeable; spark plugs are thin metallic plugs, while ignition coils are cylindrical and usually have a plastic housing. Ignition coils supply the spark plugs with powerful bursts of electricity.
