Cable Splitter Line Types and Classification
Four-cylinder engine coil-on-plug wires: Commonly found in passenger cars, typically consisting of four independent wires.
Six- or eight-cylinder engine coil-on-plug wires: More complex in design, requiring precise matching to the ignition sequence.

The Core Role of Cable Branching Cables
The distributor wire (also known as the firing wire or high-voltage ignition wire) is a critical component of the traditional automotive ignition system. Its primary function is to precisely transmit the high voltage—typically reaching tens of thousands of volts—generated by the ignition coil directly to the spark plugs, igniting the air-fuel mixture inside the cylinders and thereby driving the engine to operate.

Spark Plug Replacement Cycle and Influencing Factors
Engine type affects lifespan:
Turbocharged engines: Operate at high temperatures, reducing spark plug life by 30%-50%. Replacement is recommended every 20,000 to 40,000 kilometers.
The working principle of spark plugs
High-voltage power introduction: The ignition coil boosts the 12V voltage to over 10,000 volts, which is then transmitted via high-tension wires to the spark plugs.

The spark plug is the core component of a gasoline engine's ignition system.
Center electrode: Receives high-voltage electricity and forms a discharge gap with the side electrode.
Side electrode: Welded onto the housing, working in conjunction with the center electrode to generate a spark.
