Which Material is Best for Spark Plugs?

[Alivia]

There are many types of automotive spark plugs, and it is recommended that car owners choose spark plugs reasonably based on their vehicle usage. Here is relevant information about spark plug types: 1. Standard Spark Plugs: The insulator skirt is slightly recessed into the shell end face, and the side electrode is outside the shell end face. This is the most widely used type. 2. Projected Insulator Spark Plugs: The insulator skirt is longer and protrudes beyond the shell end face. They offer advantages such as greater heat absorption, better anti-fouling capability, and direct cooling by incoming air to reduce temperature, making them less prone to hot spots and thus suitable for a wide thermal range.
