2006-2007 GM 2500HD/3500HD 6.6L LBZ Duramax Glow Plugs

When one or more of the factory glow plugs wears on your 2006-2007 GM 6.6L Duramax LBZ, the harder it becomes to cold start your engine. Instead of relying on the operating glow plugs to start your truck when the temperatures begin to fall, it's best to get ahead of the problem and swap them out with some premium replacements. Here at Alligator Performance, we carry a selection of aftermarket glow plugs that ensure consistent and reliable performance of your Sierra/Silverado 2500/3500, giving you more peace of mind each time you turn on the ignition.
