Plug: Spark 12mm Rfi 1413211-S

This replacement spark plug is an authentic OEM item which is designed for use with Kohler engines commonly installed on lawn and garden equipment. A spark plug delivers electric current from an ignition system to an internal combustion engine. After some time spark plugs can become dirty or fouled. It is a good idea to replace the spark plug once this happens to ensure your engine runs properly. This high-quality item is sold individually. Note, 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 properly sized socket wrench to remove the old and install the new spark plug.
