The Spark Plug was an item added to the 1.5 update of Granny. It is required for the alternate escape method.
The spark plug is a device for delivering electric current from an ignition system to the combustion chamber of a spark-ignition engine to ignite the compressed fuel/air mixture by an electric spark, while containing combustion pressure within the engine.
The Spark Plug appears as a bolt-like object. It makes a tiny noise when dropped, but Granny still hears it.
The Spark Plug's usage in game is to connect the wires with the rest of the pre-installed spark plugs on the engine block in order to fix it.
