This replacement spark plug is specially manufactured for use with small engines that are commonly installed on a variety of lawn and garden equipment. It is sourced directly from original equipment manufacturer and it is sold individually. Spark plugs are used to deliver the electric current from an ignition system to an internal combustion engine. Over time spark plugs will get dirty or fouled requiring replacement. You should gap your spark plug according to the owners manual of the outdoor product you have. You would need a spark plug wrench or a socket wrench to replace this spark plug.
