Some carmakers recommend replacing the ignition coils at scheduled intervals, this schedule should be followed to reduce the likelihood of failure. Some coils will last the lifetime of the vehicle, and other may only last 5,000 miles. Most will make it 60,000 miles or more.
How many miles can ignition coils last?
The ignition coil on your car is supposed to last around 100,000 miles or more. There are a number of factors that can lead to this part become damaged prematurely. Most of the newer cars on the market have a hard plastic cover that is designed to protect the coil from damage.
How often should ignition coils be replaced?
While ignition coils do not have a service interval, they do have a lifespan. There is no specific mileage or age to replace them. They should only be replaced when they are bad. If you notice any cracks on the plastic or epoxy, and of course misfires, then it is time to replace the ignition coils.

Should I replace my ignition coils with spark plugs?
Time and mileage are enemies to your vehicle’s ignition wires and coils. Whenever you change spark plugs, it is a good idea to replace the ignition wires and vice versa. This will keep your vehicle running at peak performance and prevent you wasting money on unburned gasoline.
How long does a coil pack last?
Many coil packs don’t require service for up to 120,000 to 150,000 miles. Also, distributors are very prone to failure if they become wet or the engine happens to be submerged under water for a few seconds. Coil packs tend to operate even when they have been thoroughly doused with water.
Will changing ignition coil improve performance?
Will New Ignition Coils Improve Performance? Performance is boosted by a high quality ignition coil. Since there is an increased spark plug gap, initial flame geometry is better due to a higher voltage. In turn, the engine is now more powerful.
Will a bad coil throw a code?
a faulty ignition coil can cause several problems for your engine: 1. check engine light comes on: the car’s computer oversees coil pack operation. if it detects a problem with an ignition coil, it will turn on the check engine light and log any related trouble codes.
Can I drive with a bad ignition coil?
You can even drive with a faulty ignition coil if you have to, though you’ll notice the car running poorly. Left unchecked, an ignition coil problem can damage other parts of the car, especially the catalytic converter, which could lead to larger problems if not dealt with.
What causes ignition coils to go bad?
Ignition coils tend to fail because of bad spark plugs or plug wires. If your vehicle’s fuel-to-oxygen mixture is either rich or lean, therefore, your ignition coils may fail prematurely. Additionally, engine heat and vibrations can cause damage to ignition coils.
Can you replace just 1 ignition coil?
You can, of course, change just one coil. However, as a mechanic, I’ve seen it so many times, when one coil fails, another isn’t too far behind. If your coils are easy to access, replacing them as they fail is OK, apart from the inconvenience. It is possible to drive a car with a faulty coil, but it isn’t advised.
Are cheap ignition coils any good?
While low-grade coils cause misfiring and difficult starting, using them can have more serious consequences. As coils are controlled by the engine management computer (ECU) they rely on fly-back voltages that are fed back after the spark plug has been ‘fired.
How long does it take to replace ignition coils?
A change of an ignition coil pack can take several seconds. In most four-cylinder cars, it will take no more than one hour for your coil pack to be replaced. A larger engine will require more work and could have other components removed as well.
How much do coil packs usually cost?
Coil Pack Replacement Cost. As with any other car part, the replacement cost will depend on your vehicle’s make and model. But in general, a set of coil packs will set you back around $150 – $300.
How many engine coils does a car have?
The spark ignites the air/fuel mixture in the engine cylinders. Most modern cars have one ignition coil per cylinder. Typically, the coil is installed right over the spark plug, like in this Ford engine in the photo. This setup is called coil-on-plug.
How often should you change spark plugs and coils?
Spark plugs are somewhat durable components and don’t need to be replaced too often, that said, the general recommendation is about every 30,000 to 90,000 miles. Each vehicle may differ on when they should be replaced.
Are aftermarket ignition coils worth it?
Aftermarket ignition coils are never worth the extra few bucks in savings. In a few cases, you can get away with using a cheap universal aftermarket part as long as it doesn’t affect: The engine’s performance. The vehicle’s safety.
Are performance ignition coils worth it?
A high performance ignition coil helps engine performance four important ways. First, the higher voltage allows for a larger spark plug gap, which results in a more robust initial flame kernal at the start of combustion. The result is a real-world engine torque increase.
Are coil pack upgrades worth it?
Whether working with coil packs or traditional canister style coils, the advantage of an upgraded coil makes for a hotter spark. Intensifying the heat makes it easier to burn the fuel and air mixture. This translates to improved performance.
