Spark plugs work by providing an electric spark in a combustion chamber, igniting the mix of fuel and air that allows the engine to turn and propel a drive shaft. Insulated with ceramic to make sure the electric charge flowing through it is properly discharged, the plug is screwed into the cylinder head. The movement of the piston sucks fuel into the cylinder until it reaches the optimum level, the compression triggering the spark plug to send a pulse that ignites the fuel and pushes the piston to the back of the cylinder. This process is repeated hundreds of times a minute in an internal combustion engine. Eventually spark plugs simply wear out, particularly if they are not properly gapped, if the fuel mixture is improper, or the engine is subject to excessive use. This plug is compatible with most lawnmowers, small engines, and pressure washers made by Briggs & Stratton, Cub Cadet, and Toro. The plug itself is a guaranteed OEM part and is sold individually.
