How to Choose the Right Spark Plug?

As a Spark Plug Thread Repair Set Supplier, let's teach you how to choose the right spark plug.

The replacement of the spark plug should be based on the performance characteristics of the engine structure, especially in accordance with the specifications specified in the engine manual. If the carbon deposit is severe in the spark plug, a spark plug with a higher heat value should be selected; if the engine has a hot ignition phenomenon, a spark plug with a small heat value should be selected.

Multi-cylinder engines must ensure that the spark plug models and the old and new levels of each cylinder are unified. It is recommended to replace them in groups to avoid small losses. For imported cars, the lack of Spark Plug fittings can be replaced by domestic models. The screw length, thread diameter and heat value of the surrogate model must be the same as the original model.

Spark Plug

When choosing a spark plug, pay attention to the quality of the spark plug. Never use a poor quality spark plug. Because the working environment of the spark plug is high temperature and high pressure, the electrode of the counterfeit product is very easy to ablate. The electrode gap is too large, and the spark plug discharge energy is insufficient. As a result, the cold start is difficult, the carbon deposit inside the engine is increased, the starting speed, the acceleration performance are lowered, and the fuel consumption is increased.
