How does a spark get to the spark plug?

Primary windings create a magnetic field that when collapsed across secondary windings, create high voltage. This high voltage is required to overcome the greatest KV requirement in the secondary (normally the spark plug gap) this high voltage is transmitted from the coil to the spark plugs through a coil wire, dist cap, rotor and spark plug wires.

What causes a spark plug to pre ignite?

Pre ignition most often leads to detonation. Plug tip temperatures can spike to over 3000°F; during the combustion process (in a racing engine). Most often caused by hot spots in the combustion chamber. Hot spots will allow the air fuel mixture to pre ignite. If the piston can’t go up (because of the force of the premature explosion).

What causes a spark plug to stop working?

Most of the damage that an engine sustains when “detonating” is from excessive heat. A spark plug can deliver a weak spark (or no spark at all) for a variety of reasons. Defective coil, too much compression with incorrect plug gap. Dry fouled or wet fouled spark plugs, insufficient ignition timing.

What causes a spark plug to go bad?

Vibration damage – Constant wear and tear caused by engine vibration can loosen the electrical connection at the spark plug.
