Spark plug wires connect the ignition coil to the spark plug and are an essential part of the ignition system in many gasoline engines.

These products must have excellent insulation to protect the multimedia system and other devices inside the car from interference.

The high voltage transmission quality must not be adversely affected by the vehicle’s ambient temperature. Delivery of high-voltage pulses in the range of 25-50 kV, such wires carry out without leakage voltage with minimal losses.

What you should consider before buying spark plug wires

To avoid ending up in a fiasco, you should definitely consider a few things before buying an ignition cable product and think about the following questions:

  • What am I willing to pay?
  • Do you prefer a cheap ignition cable product or rather a branded one?
  • What features/size/color should the spark plug wire have?
  • What weight is ideal for me?
  • Are there any test reports or testimonials for the product?
  • How is the spark plug wire rated by customers?

Requirements for Spark Plug Wires

Excellent insulating properties, high heat resistance (up to 392 °F) and resistance to vibrations, and fluctuations in temperature and humidity are the essential requirements that high-quality ignition cables must meet. Only if they meet all these requirements do ignition cables offer lasting operational reliability under extreme conditions – even over a long period of time.

Types of spark plug wires

  • Spark plug wires with copper core and suppression resistor

Spark plug wires with copper core and suppression resistor consist of a copper core coated with a silicone layer that serves as an electrical insulator. Copper is an excellent conductor, but it is also very susceptible to corrosion. Therefore, the copper core of these ignition cables is tin-plated. The outer insulation of silicone rubber is resistant to temperatures up to 428 °F and to gas and oil.

  • Carbon spark plug wires

Carbon spark plug wires lead consist of a fiberglass core with inner insulation of silicone. Inside the carbon resistor ignition cable is a glass fiber braid impregnated with carbon. With carbon resistance ignition cables, the suppression resistance depends on the length of the cable.

  • Spark plug wires with inductive resistance

Spark plug wires with inductive resistance are surrounded by two silicone layers and glass fiber mesh. Like carbon resistor ignition cables, these ignition cables also have a fiberglass core. The inner insulation of silicone gives the cable more stability and protects against high ignition voltages.
