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-chambers glow plugs while the direct-injected engines have these glow plugs in the combustion chamber. The glow plug 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.

Motorcraft ZD-30 Glow Plugs - 94-03 7.3L

These did the trick. Motorcraft glow plugs are a great product and I am really glad I could order everything I needed from Jelibuilt all at once. Truck started up in 5 degree snow storm after I installed these and the relay/harness from Jelibuilt. Never started up under 35 degrees prior to install. Really happy with my purchase and the Jelibuilt support/expertise.
