Correspondingly, what happens when spark plug wires are too close together?
When routing spark plug wires to cylinders it's important to do so in sequence of the firing order to avoid crossfiring. Spacing spark plug wires too close or parallel to each other can also result in crossfiring due to the inductive field which builds up in one wire as the current flows in the other.
Additionally, is there a difference in spark plug wires? The true difference between these sets of plug wires lay in the resistance of the wires. The carbon core wire had a much higher resistance rating and limited the amount of electrical charge that was passed to the spark plugs. Because of this, resistance rating became the standard when comparing spark plug wires.
Hereof, do spark plug wires need to be separated?
YES! The high voltage running through a spark plug wire will generate an electrical field around that wire. That electrical field can induce a current in any adjacent wire that runs parallel to it. If the wires were improperly routed and not separated a problem called, appropriately, Cross Fire would occur.
Can a spark plug shock you?
You can only get a shock from a spark plug if the engine is running. A spark plug can be quite dangerous to people with a weak heart or a pacemaker. A spark plug has a lot of voltage but small amperage. In other words, the Volts are there but they have no strength.
