Modern cars usually have one ignition coil for every spark plug. So, if you have a six-cylinder engine, there is a strong possibility you have six coils. However, there are exceptions. Some cars have one ignition coil for every two spark plugs.

Should I replace all ignition coils at once?
A faulty ignition coil cannot be repaired; it must be replaced. ... In cases like this, your mechanic may recommend replacing all three rear ignition coils as a preventative measure. Whenever one of the ignition coils fails, it's also recommended replacing all spark plugs if they haven't been replaced in a while.
How many ignition coils does a 4 cylinder have?
A compact (or multi-outlet) ignition coils provide one coil per two pairs of cylinders. E.g. 2 coils for 4-cylinder engines, 3 coils for 6-cylinder engines. and 4 for 8-cylinder engines and so on.
Can you replace only one 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.
How much does it cost to replace the ignition coils?
On more modern cars, individual coils that feed one spark plug may only cost around $60 to $80 with installation ranging from $20 to $300 depending upon the location. A coil that is on the top part of the motor or on the side facing the radiator might be very simple to replace.
How many coil springs does a car have?
Most cars have four coil springs; each supporting one corner of the vehicle.
Are all ignition coils the same?
Currently most all automotive ignition coils are application-specific and are not interchangeable from one manufacturer to another. If you are asking about a different type or use of an ignition coil then repost the question with the specifics.
How often should ignition coils be replaced?
The ignition coil on car is supposed to last around 100,000 miles or more. You will have reduced gas mileage when coil begins to go bad and becomes less able to transfer power. Your car requires more fuel to run, this means you will spend more money on gas than normal.
Are ignition coils the same as spark plug wires?
The wire that goes from the ignition coil to the distributor and the high voltage wires that go from the distributor to each of the spark plugs are called spark plug wires or high tension leads.
Are cheap ignition coils OK?
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.
Is it OK to drive with a bad ignition coil?
It is possible to drive with a faulty Coil On Plug (COP), but not advisable. Driving with a faulty waste spark ignition system won't be possible. Driving with a faulty coil pack can damage other components of the engine. ... You'll also learn how to diagnose and replace your faulty coil.
Should I replace ignition coils with spark plugs?
So, should you replace coil packs with spark plugs? It depends. The most common component to replace in conjunction with the ignition coils are the spark plugs. Worn spark plugs can cause unnecessary load on the coils and there is often some overlap in the labor required to replace both components.
How many coil packs does a car have?
Modern cars usually have one ignition coil for every spark plug. So, if you have a six-cylinder engine, there is a strong possibility you have six coils. However, there are exceptions. Some cars have one ignition coil for every two spark plugs.
What causes ignition coils to fail?
Coils fail for a variety of reasons including heat, vibration, or issues on the secondary side of the ignition system. ... Worn secondary ignition components such as spark plugs or wires can cause a coil work harder, require more voltage, and therefore significantly reduce the operating life of the coil.
How long do 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.
