A spark plug is an electrical device found in the cylinder head of some internal combustion engines that carries electrical energy and turn fuel into working energy. To enable the spark plug to generate energy, it relies heavily on the spark plug wires or ignition wires.
The spark plug wires on automobiles are responsible for harnessing tens of thousands of volts and delivering that energy to the spark plugs every time the engine is started. Spark plug wires or ignition wires are connected to the spark plugs and distributor or ignition coils. Compared to typical wires, plug wires are built to have a lot of resistance. This resistance greatly reduces the radio static being generated by the ignition system. A standard plug wire has a resistance of about 10,000 to 15,000 ohms per foot of length--if it's measurably higher, the wire will probably malfunction.
However, the longer the spark plug wires goes in service, the more brittle its insulation gets and the core also develops cracks. The resulting breakdown in the spark plug wire means the electricity will be redirected elsewhere, causing engine misfiring, fouled spark plugs, and rough running. Unfortunately, spark plug wire problems can be hard to detect since spark plug wire insulation and core problems are hidden below the spark plug wire surface.
It's worth nothing that spark plugs do not actually create heat but only remove it. Working as a heat exchanger by pulling unwanted thermal energy away from the combustion chamber, spark plugs transfer the heat to the engine's cooling system. The spark plug's firing end temperature must be kept at optimum levels to prevent pre-ignition and fouling.

  • Important Facts You Need to Know About Spark Plug Wire 10 October 2012

    Are your spark plugs not getting enough juice to get your car moving? Change all that by installing a brand new set of Spark Plug Wires in your engine now.
    Electrical leakage is often the cause of engine misfire. Relax, you don't need a mechanic to solve this problem. All you need to do is replace your vehicle's set of spark plug wires. There might be exterior damage on the wires' jackets. The damage could be due to abrasion from too much engine vibrations. Other probable causes of spark plug wire damage include too much heat in the engine compartment and spilled fluids or battery acid.
    Even a small break in the insulating jackets of the spark plug wires can affect your vehicle's performance. Once the spark plug wires take electrical energy from the distributor, the electrical energy needs to be delivered to the spark plugs. If these wires aren't fully enclosed by their jackets, the electric spark may jump off the wire or arc onto something metal under the hood. These consequences aren't only dangerous; they also reduce or completely prevent the spark from reaching the spark plug. This means that the fuel-air mixture in the engine's combustion chamber can't be properly ignited. As a result, your vehicle's engine consumes more gas and your vehicle performs poorly on the road.
    Avoid these consequences by regularly checking your vehicle's spark plug wires. Auto experts suggest that inspection must be done each time you replace the spark plugs. And when it's time to replace your vehicle's stock spark plug wires, choose the best replacements only here from us. We can get you the best deals on the high-performance spark plug wires.
