Full Answer

As spark plug wires age, they lose their sharp edges, and ground electrodes become eroded. The wider the gap between the two means that greater voltage is required.

Two sources of valuable information for changing spark plug wires are the car manufacturer's recommendation and also the advice of a trusted mechanic.
