Vehicle spark plug problems that often occur, are caused by a damaged insulator. There are at least two things that cause the spark plug insulator to crack. For information, vehicle spark plugs are designed to withstand extreme temperature changes. In the cycle of suction and exhaust in the combustion chamber repeatedly. One of the important components of a spark plug that must have high resistance is the insulator. When you have a problem, the ignition system in the vehicle will not be optimal.

For that, you need to know the cause of cracked spark plug insulators that are commonly experienced by motorized vehicles. Usually the spark plug insulator is made of alumina ceramic material.

The most obvious example is the Spark plug product which produces their spark plug insulator in Japan using quality alumina ceramic materials with a very precise and complex fabrication process.
The goal is that the insulator is brittle and very hard so that it can work optimally and has a strong insulating power and is resistant to temperature changes in the combustion chamber.
Even so, it does not mean that the spark plugs are of the best quality without gaps. Because the risk of cracked spark plug insulators can still occur.

Cracked Spark Plug Insulator? This is the cause

Illustration of causes of cracked spark plug insulators
There are at least a number of causes of cracked spark plug insulators, which generally occur during improper handling. The causes include:

1.The spark plug hit under a violent momentum with a stronger material
2.The process of installing the spark plug using an inappropriate spark plug key or using a spark plug key carelessly

Motorized vehicle owners need to be more vigilant. The reason is that cracked spark plug insulators can have a significant effect on the performance of a vehicle engine. This cannot be separated from the very vital function of the spark plug in the combustion process of a gasoline-fueled engine. The spark plug insulator serves to prevent the leakage of high-voltage currents that flow the coil to the central electrode of the spark plug.

When the spark plug insulator cracks, it can potentially cause the electric current in the vehicle to leak. As a result, the flow of electric power needed to sprinkle the spark plug is not optimal, which can lead to misfire or an incomplete combustion process in the combustion chamber.
when the spark plug insulator is cracked or damaged. Can cause cars or motorbikes to be difficult when turned on.

In order to overcome this, you must pay attention to the handling and installation of the spark plugs properly. The easy effort, maybe you can use a magnetic spark plug key.
If you encounter difficult installation conditions and require an extension bar. We recommend that you use the shortest extension bar, so that the spark plug lock can stick perfectly and avoid the risk of tilt or slippage which can cause the spark plug insulator to crack.
