The spark plug wire is a cable with plastic covers at both ends to prevent moisture ingress. These covers prevent moisture from entering the connection point of the wire to the spark plug or coil, as water and moisture can disrupt the wire’s performance and sometimes cause the car not to start.
One end of this component is simple, with a metal terminal for connection to the distributor, and the rubber cover fits over the terminal after connection.
At the other end, which connects to the spark plug, there is a rubber part with better insulation properties, containing a metal wire that must be connected to the spark plug. This part is made of silver, copper, or a combination of both alloys, and it features two rubber insulators at the entry and exit points, with a thick lacquer insulation on the cable itself.
Ettehad Talaei Asia’s spark plug wires are produced from the finest raw materials using high-quality rubber.
Types of Spark Plug Wires:
1- Wire Type:
This type is rated as medium and is made of copper alloy, with limited flexibility and low resistance to conductivity. It is used in carbureted vehicles.
2- Silicone Type:
This is considered one of the best models, used in both modern fuel-injected and carbureted vehicles due to its good flexibility, high resistance, and high noise suppression. Instead of wire, it uses graphite-coated threads that resemble silk for high voltage transmission.
3- Hybrid Type:
This type is a combination of the first two types, offering better performance than the wire type.
Problems Caused by Spark Plug Wire Failure:
1- Reduced engine power.
2- Excessive engine pressure raises the temperature.
3- Incomplete combustion, leading to increased fuel consumption.
4- Excessive engine vibration.
5- Increased emissions from the vehicle.
6- Melting of the spark plug electrodes and center electrode.
To prevent these issues, safety measures should be observed. Regular inspection and servicing of this component, along with awareness of its lifespan, are recommended.
It is best to replace this part every 20,000 kilometers.
The spark plug wire is a crucial component for vehicle health. Ettehad Talaei Asia, leveraging its extensive experience, supplies high-quality auto parts and accessories for domestic vehicles across the country.
