Motorcraft ZD11 OEM Replacement Glow Plugs

We recommend only using the OEM Motorcraft ZD-11 replacement glow plugs to avoid the potential failure of the tip. Many aftermarket, less expensive glows plugs have the danger of broken tips that seperate from the main body. After failure the tips could fall into the engine causing catstrophic engine damage. For full cold start protection add a new Glow plug relay.

Glow Plug Features:
  • OEM Ford Glow Plug
  • Lower Failure Rate
  • Doesn't Separate Inside the Engine
  • Highest build quality
  • Single glow plug.
  •  Add 8 for the entire engine.
Motorcraft are the best Glow Plugs:
Using parts store brand glow plugs can lead to engine failure. We use exclusively Motorcraft for that reason. For a glow plug kit add the Alliant relay. Replacing the glow plugs is recommended anytime your inside the valve cover and you're glow plugs are more than 1 year old.Price is for 1 glow plug. Eight are need for the entire set.

A glow plug is a heating device used to aid starting diesel engines. In cold weather, high speed diesel engines can be difficult to start because the mass of the cylinder block and cylinder head absorb the heat of compression, preventing ignition due to the higher surface-to-volume ratio. Pre-chambered engines make use of small electric heaters inside the pre-chambersglowplugswhile the direct-injected engines have these glowplugs in the combustion chamber. The glowplug is a pencil-shaped piece of metal with a heating element at the tip. This heating element, when electrified, heats due to its electrical resistance and begins to emit light in the visible spectrum, hence the term "glow"-plug. The visual effect is very similar to that of a toaster. The fuel injector spray pattern then impinges directly upon the hot tip of the glow plug during the injection of fuel at top dead center. This enables the fuel to ignite even when the engine is insufficiently hot for normal operation. This reduces the cranking time needed to start the diesel engine.
