How To Stop Spark Plug Wires From Arcing?
Many reasons contribute to the spark plug wires arcing. Weak ignition coil, defective wires, bad electrical connection, and so forth. They play a major role in causing spark plug wires to arc.
So, how to stop spark plug wires from arcing? Below we discussed how you can stop your plug wires from arcing.
Cleanliness is a virtue, and it’s no different here either. We recommend you properly clean the wires every 20000 miles. You can clean them in a variety of ways. Furthermore, you can use a napkin to clean the spark plug hole and sandpaper for the exterior.
If you are wondering what to spray in spark plug hole? You can use carb cleaner or WD-40, clean them with a napkin, airgun, etc. Nevertheless, check the link where we have covered it in detail.
Changing The Ignition Coil
The most common cause of arcing plug wires is faulty ignition coils. If your ignition coil has failed, it will provide less voltage than it should. Furthermore, it could overheat, and so on. Replace faulty ignition coils as soon as possible.
Inspect The Wires
Over time, the spark plug wires could deteriorate. So it’s a good idea to check in on them every now and then. If they are defective, they will overheat, have poor insulation, and so on.
You can easily detect and investigate any faults with an arc-fault detection device.
Check For Any Disconnected Shift Linkage

That being said, you can use them in an emergency.
Will Cleaning Spark Plug Wires Reduce Arcing?
Yes. Proper care of your wires will ensure a reduced chance of arcing.
Why Does The Ignition Coil Arc?
The ignition coil sends a spark to the plugs, which then help the engine to start. They are very important, and high voltage current flows through them. As a result, they sometimes face corrosion, leaks, overheating, etc. When the coil case leaks due to overheating, they cause the wires to arc.
