You may know this part of your engine, the ignition coil system when you do your regular maintenance and servicing every time, spark plugs and the ignition coils go together hand in hand in order to produce that ignition spark that gives the engine that roar, that breath of life into the car. But do you know what's the exact function of it and what performance coils does?
Lets start with the basics:
1.What is an ignition coil?
All ignition systems for modern petrol engines use ignition coils for the same basic function: to create the high voltage required to produce a spark at the spark plug. For combustion to take place, a spark is needed to ignite the fuel mixture in the engine.The heart of this system is a device called an ignition coil.
2.What are performance ignition coils?
Highspark Ignition coils are one of the best aftermarket coils in the world. Designed to produce a higher energy spark over a long time, it allows greater voltage (15KW compared to original 10KW) and current to be supplied to the car's engine safely, increasing the torque and pick up power for the car. It is also able to ignite 2 to 2.5 times from a single spark signal.It also reduces the jerky feeling at re-start and when using the accelerator on-off, which tend to happen with other reinforced coils.
All coils are tested 3 times and working 100% 1 year 30,000km warranty
3.Signs of faulty/damaged ignition coils
A misfiring engine-
If an ignition coil is not working properly, your engine will likely misfire. A misfiring engine results in a jerking or sputtering feel when you are moving at normal speeds. When you stop, a misfire from a bad ignition coil may cause your vehicle to run roughly, vibrate or shake.
To run, your vehicle's engine needs a spark at the right time. If a spark plug is not getting the right voltage to create a spark, you may experience a hard start. This may mean the ignition coil is not working properly. While this problem can happen with any coil configuration, it is more common with engines that have a single ignition coil.
Ignition coils can either fail completely or fail intermittently. This means that you may have a coil that goes bad over time. Accordingly, even if your vehicle seems to be performing normally, you should watch for worsening gas mileage. Even if it is not caused by a bad ignition coil, decreasing gas mileage is a sure sign that something is wrong.
Loss of power-
Vehicles with bad ignition coils often run roughly. This means, when your vehicle is idling, you may notice a rough feel or sound. Your vehicle may also experience a drop in power. As a result, a bad ignition coil can make it acceleration more sluggish. The vehicle may even stall.
A faulty ignition coil is enough to create a check light. If you have an OBD-II diagnostic scanner, you may see a P0351 ignition code. Of course, because all cars are different, an ineffective ignition coil may register a different code for the problem. Alternatively, you may see a code for an engine misfire, which could be the result of a dead ignition coil.
