Spark plug wires, also known as ignition wires or high-tension leads, are crucial components in the ignition system of internal combustion engines. These wires are responsible for transmitting the high-voltage electrical current from the ignition coil to the spark plugs, initiating the combustion process within the engine cylinders. High-quality spark plug wires are essential for ensuring efficient ignition, optimal engine performance, and reduced emissions, making them a critical component in the overall efficiency and environmental impact of the vehicle.
In addition to its excellent temperature resistance, it is also resistant to ozone, light, and weather conditions. Silicone can be typically found in the food and medical industry as well as in hydraulics and pneumatics. It is often the preferred material for o-rings, moulded parts and flat seals but is also commonly used for electric insulators due to the material’s translucency and flexibility.
