Diesel Glow Plug
Starting a diesel engine? Check out Autolite® Glow Plugs. They're dependable and long-lasting, the perfect plug for a variety of diesel applications.

Diesel engines depend on high heat in the combustion chamber to ignite the fuel, and when you cold start a diesel engine, there isn't enough heat to get it going. When you turn the ignition switch, the glow plug warms the combustion chamber to start the fuel ignition. If you're experiencing problems starting your diesel engine, it may have burnt out glow plugs. For dependability and long-lasting performance, use Autolite® Glow Plugs.
