Spark Plugs

What is a spark plug?
A spark plug is an auto part. Specifically, a spark plug is one of the components of an automobile's starting system. It is usually used to begin combustion for spark-ignition engines in automobiles. Sometimes, spark plugs are also called as flame igniters because they can be used in many other applications where need to ignite a combustible mixture.
Spark plugs are usually composed of terminals, ribs, insulators, metal case and electrodes, etc. Each component has its specific function. The terminal is a necessary part of a spark plug and functions to connect to the ignition system. The insulator functions to offer mechanical support to the center electrode and at the same time insulate the high voltage. Insulators like ribs and insulator tips are mainly used for improving the electrical insulation and preventing leakage of electrical energy and so on.
We at DEMY can provide 21 series and over 200 varieties of spark plugs for vehicles, motors and other gasoline engines. Welcome to choose.

Why choose DEMY spark plugs (auto part)?
1. Multi-ribs of insulator help eliminate flashover.
2. Equipped with alumina made insulators, our spark plugs have strong resistance to heat shock, great mechanical and electrical features as well as super insulation characteristic.
3. Nickel plated housing help prevent spark plugs from oxidation and corrosion. And gas-tight fit is guaranteed by our adoption of heat crimping process.
4. Conductive glasses are adopted for inner sealing, which makes our spark plugs have good conductivity and sealing.
5. Additionally, good sealing is also ensured by our multi-layer gaskets.
6. Our copper core electrodes feature having good oxidation and corrosion resistance, good electric and heat conductivity. And they also enable our spark plugs to have longer service life.
