In automobiles, the spark plug is an indispensable part, but it is also a common cause of engine ignition failure. There are some taboos to keep in mind when using it.

1. Avoid long-term use:

The service life of the spark plug is limited. If it is overloaded, it will affect the normal use of the car engine.

2. Avoid fire:

It was found that some people use fire to remove the dirt in the spark plug electrode. This is very undesirable. It is difficult to control the temperature when the internal fire is burned, and it is easy to burn the insulator, causing cracks and leakage.

3. Do not clean up carbon deposits for a long time:

During use, the electrode and skirt will produce carbon deposits. The more carbon deposits, the more likely it is that the flame cannot be flashed.

4. Avoid too tight installation:

When installing spark plugs, you need to follow the regulations. There are many cars whose spark plugs have a torque of 40N.m. If they are installed too tightly, the porcelain core of the spark plug will be damaged.

5. Don't diagnose errors:

When it is suspected that the spark plug is malfunctioning, if you do not know the knowledge of troubleshooting and maintenance, it is recommended to have a dedicated technician handle it.

The above points are to be avoided when using spark plugs. If you have one of the situations described above when using car spark plugs, you should stop as soon as possible.
