NGK Glow Plug is manufactured to ensure fast ignition even at temperature below freezing point. It is constructed from durable material which is corrosion and abrasion resistant. This glow plug is fitted in the cylinder head and the glow pencil protrudes into the glow chamber which helps heat up the air in the chamber up to 800 degree. This enables the diesel fuel to be ignited more quickly. It ensures longevity and can be easily installed.
