Which brand of spark plug is better?

Different people have different opinions about which brand of spark plug is the best. Next, introduce several better brands of spark plugs.

1. Bosch, Germany, one of the top 500 auto parts manufacturers in the world, is mainly used for German cars. However, due to too many Bosch products and insufficient concentration, the quality of spark plugs produced by Bosch in China is uneven.

2. Extreme combustion, China fuel-saving spark plug with the highest performance in the world has great performance advantages over any spark plug brand in terms of fuel saving and power improvement. The only national brand that has the potential to break the monopoly of foreign brands, but its popularity is low at present.

3.NGK is one of the best spark plugs produced in Japan, and its quality is highly praised. Together with Japanese cars, it has occupied a large market share in the world.

Although the spark plug is a small part of the car, it plays a huge role. The ignition system of the engine introduces high-voltage current into the cylinder to generate electric spark, thus igniting the combustible mixture. The spark plug is mainly composed of a connecting nut, an insulator, a connecting screw, a center electrode, a side electrode and a shell, and the side electrode is welded on the shell.
