Your Hummer Spark Plug is an electrical device fitted into the cylinder head of some internal combustion engines. It facilitates the compression of aerosol gasoline by generating sparks. Electricity runs through the spark plug to arc across a gap that looks like a bolt of lightning. Such high-voltage electricity flows across the gap and creates a good spark. A spark plug can drive voltage that ranges from 40,000 to 100,000 volts. High voltage automatically travels down the electrode while an insulated passageway is provided for the spark plug. This permits the voltage to jump over the gap and finally conduct into the engine block.

A quality Hummer Spark Plug should withstand extreme heat and pressure inside the cylinder. This must prevent scaling from fuel additives. A useful piece of equipment referred to as the Ceramic insert is used to isolate the high voltage at the electrode within the spark plug. This ensures that the spark is driven at the tip of the electrode and not anywhere else on the plug. The Ceramic insert performs such important task while burning off deposits. It serves as a conductor for the material during operation. The heat it produces is used in the electrode to burn off deposits.

A hot plug, which is sometimes required, is composed of a ceramic insert that's slightly brought in contact with the metal portion of the plug. Its task is to reduce heat transfer from the ceramic. Its main aim is to burn more deposits. A cold plug, on the other hand, is intended for larger contact area that needs to run cooler.

Some manufacturers have their exclusive design for Spark Plugs on particular year, make, and model. Vehicles having high-performance engines are naturally generating more heat, thus they employ colder plugs. Once it gets hot, the spark plug will ignite the fuel before firing the sparks. The manufacturers have designed the appropriate spark plugs for certain vehicles, thus the Hummer Spark Plug for your vehicle must be chosen according to the manufacturer's given specifications. The appropriate Spark Plug will help you sustain the excellent performance in your ignition system.
