Frequently Questions

Based on our experience in spark plug cable manufacturing, we try to answer some of your questions. If you have any other questions, you can write to us.

How do spark plug wires work?

Spark plug wires , Ignition leads, also known as Ignition wires, are the cables that connect a distributor, ignition coil, coil pack, or magneto to each of the spark plugs in some types of petrol combustion engines, to ignite the fuel-air mixture in the cylinders.

How often should you change spark plug cables?

We recommend changing them usually between 20000 and 40000 km.

How long do spark plug cable last?

The spark plug cables on a car are made to last about 20000 to 40000 km before they have to be replaced. In some cases, the cables will need to be replaced due to the rubber boots on the end getting damaged and not passing current to the spark plugs for a good connection.

What are the types of ignition systems?

There are three basic types of automotive ignition systems: distributor-based, distributor-less, and coil-on-plug (COP).

Is the cable quality important for the spark plug cable?

Yes, it is very important. For example if you use poor quality spark plug cables and the material of the cable is PVC, it can melt at very low degrees like 90°C, but quality cables with Silicone insolation and silicone jacket has a very high temperature resistance up to 240°C.

Will wrong ignition order damage engine?

When the ignition order is wrong or delayed, the engine does not run correctly. The spark will be delivered to the cylinder when there is no fuel/air mixture or before it is properly compressed. One symptom of an incorrect ignition order is the engine does not run. Turning the ignition does not start the engine.
