The Spark Plug Terminal Top is the exposed end of a spark plug that connects to the ignition system and protrudes into the engine's combustion chamber. It consists of a metal shell with a center electrode and a side electrode, forming the spark gap. The spark gap is essential for producing the electrical spark that ignites the air-fuel mixture in internal combustion engines. Some spark plugs include a resistor to reduce electromagnetic interference, and they have an extended terminal top to improve combustion efficiency. It is vital to use the recommended spark plugs.

Attributes:
• Resistor-equipped types reduce electromagnetic interference
• Proper ignition contributes to better fuel combustion, resulting in improved fuel efficiency
• Ensures timely and consistent ignition, leading to efficient and smooth engine performance
• Ensures reliable starting of the engine, even in different weather conditions

Applications:
This Spark Plug Terminal Top is to create the electrical spark that ignites the air-fuel mixture in the engine's combustion chamber initiating the combustion process.
