How Spark Ignition Wires Transfer Energy

Spark plug wires (also referred to as ignition wiring) transfer the spark from the distributor or ignition coil to the plugs. The subsequent spark ignites the air-fuel mixture in the combustion chamber of your engine. This process starts with the ignition coil, which transforms low-voltage power into extremely high voltage. However, the transfer of this energy through the ignition wires creates heat. Over time, the ignition wiring can become brittle, crack or breakdown. In such cases, a weak or non-existent spark can cause the failure of the fuel in your engine's cylinder to ignite. Depending upon how many spark ignition wires are bad, your car or truck will run poorly, or not at all.

Unfortunately, your spark plugs and ignition wires never get to rest while the engine is running. Moreover, an engine's spark plugs must remove excess heat from the engine's combustion area every time combustion occurs in each of the cylinders. There are many variables that determine the amount of voltage needed per cycle. A spark plug must be capable of firing at the right piston position in each cylinder at a very high rate of speed. Subsequently, the total number of sparks required is determined by multiplying the number required per minute times the number of cylinders.

Whenever you change spark plugs, it is always a good idea to replace the ignition wires, and vice versa. Since heat and mileage are enemies to your vehicle's ignition wires and coils, this will keep your vehicle running at peak performance year round and prevent you from wasting money on unburned gasoline. In fact, any sudden drop in your vehicle's gas mileage may be an indicator that your ignition wires or spark plugs are not functioning properly. A quick check with an Ohmmeter can determine how much voltage is reaching each plug. If the "Check Engine" light in your vehicle comes on, it is important to have someone check the codes to determine if spark plugs or ignition wires are the cause.

Since every engine has and needs a healthy ignition system, ask your service technicians to replace your worn parts with new E3 spark plugs and ignition wires. Our ignition wires have a tempered outer silicone jacket with custom-designed spark plug boots and sleeves for a perfect match.
