A spark plug wire is not something we give a lot of thought to. It’s a simple and fairly inexpensive item, but a cheaply made spark plug wire can cause you no end of grief. Of course, some plug wires are more durable than others, and it’s always a hassle when the wires you bought new just six months ago are already brittle and cracking. There’s another annoying problem that you might hear on your radio. That’s electromagnetic radiation from poorly shielded spark plug wires – it’s that static-like whining noise in the background that rises and falls with your engine’s RPM’s. There’s another problem you may experience from the use of cheap spark plug wires, and this one is potentially serious. It’s known as “crosstalk,” and when it happens, current jumps from one wire to another, causing cylinders to fire out of order. This can lead to some major damage if not corrected.
