All Chevy Impala Spark Plug Wires are not the same. It may seem like a small thing, but when spark plug wires are defective, deteriorating or poorly-manufactured, they can cause no end of troubles. When spark plugs fire, they can cause electronic interference.

With inferior plug wires, you may actually be able to hear static on your radio that rises and falls with the engine RPM. It may interfere with other electronic devices as well, including electronic ignition, fuel injection, and on-board computer engine management systems.

Such electro-magnetic interference can also cause a phenomenon known as "cross-talk." Current may jump between different wires, causing cylinders to misfire or fire out of sequence and in the wrong position. Poor performance and carbon build-up on the valves can be the result. Superior Chevy Impala Spark Plug Wires feature "variable pitch" wire winding, which prevents radio frequency interference and cross-talk.
