About Duramax Glow Plug

You are wrapped in layers of clothing as you head out to your truck, knowing that as much as you struggle to get up and going on a cold morning, so does your engine. Engines require heat to get started, and when the chill of the air is just too much to allow your truck to start, a Duramax glow plug steps in to provide an extra surge of heat to get the engine going. This tiny device gets its name from the bright, visible glow that appears on the tip of the plug as it produces heat. For those trucks that do not have advanced computerized systems to produce extra heat in response to cold weather, these plugs generate a directed, concentrated point of heat to spark ignition in a diesel engine, much like spark plugs work in a gasoline engine. Many of these plugs are compatible with several model years, so check your engine to ensure that you choose the right Duramax glow plug for your vehicle. Explore the vast inventory on eBay and prepare your truck for the next frigid morning.
