A Hummer vehicle part that is responsible in harnessing tens of thousands of volts and then delivers it onto the spark plug is the Hummer Spark plug wire. It can definitely affect the performance of the Hummer vehicle as well as the fuel mileage of the Hummer engine. The Hummer spark plug wire connects the distributor on to the spark plugs, and then a similar wire connects the distributor on to the coil.

As the Hummer engine runs, the coil then transforms the 15 volts from the vehicle alternator at about 100,000 volts, and then sends it on to the distributor. The distributor then is the one that sends the voltage on to one spark plug at a time that is through the Hummer spark plug wire. As time pass by, the Hummer spark plug wire insulation gets brittle and develops cracks on its core. Such breakdown in the Hummer spark plug wire is definitely not good news, for any breakdown gives the electricity to go somewhere else and the result would be misfiring of the engine, fouled spark plugs, and Hummer vehicle having a rough running.

The big problem regarding the Hummer spark plug wire is it is not that easy to detect, since its insulation and the core problem is located just below its surface. In order for the Hummer engine to be able to run efficiently, the proper voltage should be carried through each of the Hummer spark plug wire. As time passes by, the resistance of the flow of electricity within the Hummer spark plug wire will then begin to grow, and because of such deterioration from a high heat of the voltage, it carries plus external force. However, a new set of Hummer spark plug wire can restore the ignition performance of a vehicle.

Replacing of the Hummer spark plug wire is a normal part of the annual tune up of the Hummer vehicle. For a higher performance application, there is a version of the Hummer spark plug wire that reduces the resistance to an electrical flow. Remember to check the other ignition components of the vehicle when installing high performance Hummer spark plug wire or replacing Hummer spark plug wire
