Buying Guide of Spark Plug Wire
Here is the list of parameters you should keep in mind in order to buy the best spark wire plug.
Heavy-duty insulation is a must-have for every spark plug wire. The exterior has to be strong to provide good insulation to the interior wire. Some spark plug wires can also come with double insulation, whereas others can have superior silicone insulator. Good insulation can provide consistent performance and can resist wear and tear. It helps to protect the core from heat and minimize the loss of energy. Insulation can also help in electromagnetic interference and prevents the electrical charge to leak in the outer layers.
In a spark plug wire, resistance is one of the most important things to avoid hazards. Good resistance will have that perfect flow of electric current. It will ensure that less current will flow from the source to the plug. This is very important as it can affect the performance of the engine. It can also affect the fuel economy and delivers optimal performance.
EMI or RFI Interference
Electromagnetic fields form when the electronic ignitions move through the wire. The electromagnetic field has the ability to interfere with sensitive electronic devices and can affect the sensors by creating noise. Radio frequency interference or electromagnetic interference can cause destruction when there are sensitive radio communications. It is always important to see if the spark plug wire has high EMI/RFI suppression.
Solid core employs stainless steel or copper material and provides good electrical conductivity. This has lower resistance and provides maximum energy. However, the solid core has less EMI suppression making them unsuitable for the electronic ignition system. Spiral core utilizes alloy comprising of tin, stainless steel, and copper. It maintains a delicate balance and reduces the noise for increasing the resistance. Carbon core is the most common style OEM core. It has outstanding EMI suppression and can be an ideal choice for vehicles. However, they need frequent replacement as it breaks down more quickly.
Braided and Suppression Layer
A braided layer usually has strong fiberglass material and provides strength. It has also EMI suppression for better performance. Some spark plug wires can come with suppression or conductive layer to safeguard from the loss of energy.
Apart from the above, you can see if the spark plug wire has good resistance to a high temperature so that you can use it in extreme conditions. The outer jacket has to be strong and have the capability to protect the inner layer from abrasion, heat, and chemical. You can also see if it is resistant to moisture as well as petrol and oil.
We have listed the best spark plug wire from the best brands such as NGK and ACDelco. There are different types of spark plug wires available to choose from. Go through the buying guide, and you will be able to choose the best product for your vehicle. If you have some knowledge, you can change the spark plug from time to time whenever the malfunctioning starts and performance goes down.
