This spark plug is a genuine OEM part that is used on gas-powered lawn and garden equipment. It is a small cylindrical device in the engine cylinder head that creates the spark that ignites the fuel and air mixture inside the engine. It has a ceramic insulator, a metal rod, known as the center electrode, and a metal tab at its base, known as the ground electrode. The spark plug may fail due to a buildup of carbon, physical damage, or fouling. If it is faulty, your engine will misfire, consume more fuel, and have difficulty starting. To check that the spark plug is faulty, you can visually inspect it and use either a multimeter or a spark tester to check for electrical failure. Remove the faulty spark plug using a spark plug socket and ratchet. Use your hands to carefully thread the new spark plug into the engine. Regularly inspect and replace your spark plug as part of your general maintenance to keep your equipment in good condition.
