Spark-Plug is a device intended to fit in each cylinder of a gasoline-powered internal-combustion engine to produce the electric spark for ignition while glow plug is fitted into each cylinder of a diesel engine to heat incoming fuel and to ensure efficient combustion when the engine is cold. United Kingdom Automotive Spark-Plug and Glow-Plug market is expected to grow on the back of increasing automotive production as vehicle manufacturers like Daimler AG, Volkswagen AG are present in the European countries and emission norms. In United Kingdom, diesel vehicles are predominant, resulting in the growing demand for glow plugs. Moreover, continuously expanding fleet size will grow the Spark-Plug & Glow-Plugs market during the forecast period.
