While the amount of radiation from the plugs was minuscule and not a threat to the consumer, the benefits of such plugs quickly diminished after approximately a month because of polonium's short half-life, and because buildup on the conductors would block the radiation that improved engine performance. Spark plugs use ceramic as an insulator, which helps manage heat and prevents the electrical spark from grounding out. Its the cheapest place to start. Although they are more expensive than other spark plugs, their longevity and ease of use are tough to beat, especially in hot engines. The ignition coil then generates the high voltage needed to create the spark from the plug. Please seek the advice of a certified technician if you have any questions or concerns related to the content of this article. One of the key features of the plug is its high melting point, making the plug more suitable for engines that are generally in a greater heat range than most vehicles. The temperature of the end of the plug\s firing end must be kept low enough to prevent pre-ignition, but high enough to prevent fouling. Spark plugs have an insulated center electrode which is connected by a heavily insulated wire to an ignition coil or magneto circuit on the outside, forming, with a grounded terminal on the base of the plug, a spark gap inside the cylinder.
