This spark plug is a genuine OEM sourced replacement part. It is used with Makita gas powered trimmers and backpack blowers. A spark plug delivers electric current from an ignition system to an internal combustion engine. Symptoms of a bad spark plug include difficulty starting, misfiring or the inability to start the engine at all. Please note, this item is sold individually.
You would need a spark plug wrench or a socket wrench to install the spark plug.
