Spark Plug - W16epr-u - Denso 98079-55855

This replacement spark plug is specially manufactured for use with Honda engines which are commonly installed on a variety of lawn and garden equipment. It is sourced directly from the 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 a replacement. You should gap your spark plug according to the owner's manual of the outdoor product you have. You would need a spark plug wrench or a socket wrench to replace this part.
