The spark plug cable is a part of a vehicle's ignition system and carries the high voltage between the spark plug and the ignition coil. The characteristics of the spark plug cable affect performance and durability. Here are the spark plug cable specifications in general:

1. Material: Spark plug cable is usually made of high quality conductive material. Conductive materials such as copper, gold, platinum and its alloys are commonly used.

2. Conductor Diameter: The diameter of the conductor affects how well the cable can conduct electriccurrent. Thick and well-conducting wires generally provide lower resistance.

3. Insulation Material: The outside of the spark plug cable is usually covered with insulating material. Silicone, EPDM (Ethylene-Propylene-Dien-Monomer), and other types of durable rubber are often used.

4. High Voltage Resistance: The spark plug cable must carry the high voltage from the ignition system and must be high voltage resistant due to its insulation properties.

5. Heat Resistance: The spark plug cable must be able to withstand high temperatures in the engine compartment. This helps it maintain its performance in combustion chamber temperatures and the heat generated when the engine is running.

6. Flexibility: The spark plug cable should generally be flexible so that it is not damaged by vibration and movement of the engine.

7. Water and chemical resistance: The spark plug lead must be resistant to oil, water, and other chemicals. This increases durability when exposed to various conditions in the engine compartment.

8. Electromagnetic interference blocking: The spark plug cable can be specially designed to prevent electromagnetic interference. This helps ensure a healthy ignition signal without damaging other electronic components.

9. Color and Coding: Spark plug cable are usually color coded or numbered. This helps ensure proper connection during installation.
