Diesel Glow Plugs

Diesel engines use compression to induce combustion, unlike gasoline engines, which use spark plugs. When diesel engines are cold, however, compression is enhanced by the introduction of a pre-heater, known as a glow plug. Once activated, the glow plug, which has coiled wiring in its tip, flares up and emits an intense electrical heat that warms the combustion chamber and assists compression during a cold-start. It can also be used for post heating, which can improve fuel and emission performance. With NAPA Echlin's Diesel Glow Plug installed, startup time will be reduced. Plus, when the engine does start, there will be less smoke and reduced emissions. That’s because our glow plug has an improved tip design.
