The Benefits of Ignition Coils
Remove the Check Engine Light
One common reason you could be getting a check engine light is from a bad coil. This would cause the dashboard light to illuminate and you may start to worry that something is wrong with the engine.
Start by using an OBD-2 scanner to check the code. If it’s related to these coils, replacing or upgrading the coil could turn the light off and get the engine running back to normal.
Better Starting Conditions
A worn or damaged ignition coil can prevent the engine from starting. Installing new coils can improve the starting conditions and make sure your vehicle starts every time.
This is something to look into if your vehicle is having trouble starting. You can also check out this issue if you have long crank times or you’re getting misfires.
Driving with a broken ignition coil can make the engine backfire, cough, or run rough. This is usually caused from a cylinder misfire and fouled spark plugs, due to a bad coil.
This would lead to a loss of power and resulting other symptoms when you’re driving. Changing the coils can improve performance and help you get the most out of your engine.
Better Gas Mileage
The engine in your vehicle is bound to operate better when you install new ignition coils. With the engine operating at its peak performance you’ll end up with better gas mileage.
If you noticed your vehicle starting to suffer from lower gas mileage, checking the ignition coils can be one way to remedy these symptoms. It doesn’t hurt to replace them regularly as well for better engine performance and longevity.
Types of Ignition Coils
Breaker Point-Type Ignition Coil
This coil is typically used with conventional breaker point type ignition systems. It’s a system that has been used since the beginning of the 20th century.
The way it works is by having an electrical current flowing into the coil from the battery, then the distributor cam opens the points. This causes the electrical circuit in the coil to break with the current falling into the distributor cap and on to the spark plugs.
Ignition Coils Used in Electronic Ignition Systems
This type is very similar to a conventional coil. The difference is with the two ignition coil design.
For this design to work, a pick-up coil is employed to signal the control module. This signal from the control module activates the ignition coil.
Typically, these ignition coils can be found in the distributor cap. This was a setup of coil arrangement used in the 70s since it produced a more reliable engine operation and less pollution.
Ignition Coils in Distributorless Ignition Systems
Since the 1980s vehicle makers have started to use these ignition coils. The effective design of the distributorless systems means more energy can come from the coils.
With this configuration, three or more ignition coils are mounted together in a coil pack. There is a magnetic triggering device that determines the position of the crankshaft and the engine speed.
This device sends a signal to the ignition control module, which then sends a signal to the coil. Each coil fires the spark plug in its own cylinder, which eliminates the fault-prone and distributor ignition wires.
How Much Do Ignition Coils Cost?
$20 to $50
This is at the lower end of what you can expect to spend for one ignition coil. For the price you can find some decent quality coils, though you’ll be looking at breaker point type coils designed for older vehicles.
At the higher end of this price range you can find coils designed for vehicles with electronic ignition systems. Depending on the vehicle, the electronic ignition system may use two of these and it will be necessary to replace both of them.
Choosing the right package depends on the number of cylinders in your engine. This means you’ll either purchase 4, 6, or 8 cylinders.
$50 to $75
This is what you can expect to spend for coils design for electronic or distributorless ignition systems. These can typically be found in mid-quality cars, such as Toyota and Ford, that are equipped with 4, 6, or 8 cylinder engines.
$75 and Up
You’ll typically find coils in his price range for distributorless ignition systems. These are typically designed for higher-end cars, such as Lexus and Mercedes.
Always double-check with your owner’s manual or the maintenance manual for your specific vehicle. This will tell you exactly what to look for when it comes to finding the right ignition coils for your car.
The first feature to consider is the overall quality of the coils you’ll want to use in your vehicle. Modern coils use epoxy to eliminate any gaps in the windings, which would cause problems in the future.
They also come with a diode to stop any reverse pulses that could form. It’s a good idea to upgrade to modern materials, unless you’re restoring an older vehicle or you want to keep everything original.
When you’re replacing the coil, look for the best quality ignition coil that’s made from the best materials. This isn’t an area of vehicle maintenance that you would want to cheap out on.
