Spark plug cables are TVRS, which means Television and Radio Supression. The electrical pulse that flows in a spark plug circuit is made up of many frequencies some of which cause static or snow on other electronic devices. This applies not only to your car radio but any other radios or TVs that you might drive near. For years, Ford placed the distributor for their V-8 on the front of the engine. When someone replaced the TVRS cable with copper wire, it become a multi-frequency generator and caused problems in any house they drove near. My neighbor's son did just that and when he drove in the driveway our TV went crazy. Modern cables are not even wire but are nylon string impregnated with carbon. As other posters have stated, the correct cables are a balanced matched set and if replaced should be replaced with a like set. The resistance of the cable also limits the current which prolongs the life of the other components. With modern cables, unleaded fuel and plated spark plugs it is not uncommon to see a set of plugs last over 100,000 miles.
