Features To Consider While Buying The Best Glow Plugs For 7.3 Powerstroke

Powerstroke engine has a specific need that can only be fulfilled by a specific glow plug. One should look for a highly durable glow plug that can match the engine output of the Powerstroke 7.3 in the nail-biting winter.

#1 Non- Corrosive

You might know that spare parts like glow plugs are prone to corrosion since they are made of metals like copper that degrade with the contact of moisture and excess friction.

 To avoid this, it is a must for a glow plug to have an external coating of a less reactive metal to help the glow plug last longer.

Apart from a sacrificial metal, a synthetic rubber seal is also used to serve the purpose. These rubber shells sustain themselves against the external oxidizing agents very well. Motorcraft ZD11 glow plug, a stainless steel glow plug, is the one that falls under this category.

#2 An Additional Coil To Regulate And Maintain The Temperature

Several advancements have helped to improve and enhance glow plugs over the years.

Like, the SRM Glow Plugs are one example. 

Such glow plugs have double coats of coils, where one is a heating coil, and the other is a regulating coil.

The latter coil sustains a constant high temperature and avoids any drop in the thermal reading when the heating coil hits a temperature of 900 C. In this way, the glow plug keeps running for a long time, like in Bosch glow plugs.

#3 An Excellent Core Material

One of the main components of a glow plug is its core. The stronger and purer the core material would be, the elite the glow plug will be. Therefore, a good quality iron core is a must for a glow plug to function at its best.

Today, manufacturing companies use alloys of iron rather than pure iron to deliver high heat transfusion from the glow plug to the diesel engine. An alloy-based core made extensively of iron will offer good mechanical strength and will last longer.

#4 Proper Insulation

Insulation is an important aspect to boost the work efficiency of a glow plug. However, a suitable quality plug that has below-average insulation is not worth the price. 

That’s why before you make your purchase, don’t forget to check if the glow plug offers a Magnesium oxide powder coating for excellent protection or not.

SRM Glow plugs offer Magnesium Oxide coating over their glow plugs that protects them against damage. 

Not only that, MgO is electrically insulated and thus, provides proper insulation against electrical discharge to the glow plugs.

#5 Types of Glow Plugs

5.1 Pressure Sensor Glow Plugs (PSG)

A pressure sensor glow plug is a glow plug that electronically enhances the efficiency of the plug by cutting particle emissions. In this way, it helps the glow plug to reach its maximum gas limit.

The PSG uses an inbuilt sensor to gauge the pressure in the combustion chamber and sends the information to the engine management electronics, which determines the glow plug’s required heating pattern.

5.2 High-tech Steel Glow Plugs

The high-tech steel glow plugs are an excellent choice for two- and three-phase glow technologies since they are fast, durable, and eco-friendly. The following are the main differences:

  • Three-phase technology (Types GE & GN) – these glow plugs use three heating phases (preheating during ignition, heating during starting, and post-heating for about 3 minutes after starting) to ensure diesel fuel burns more efficiently and quietly, with up to 40% less exhaust gas clouding during cold starting. Even when the outside temperature is -30°C, they guarantee dependable starts.
  • Type GV glow plugs (two-phase technology) — these glow plugs are designed to meet older diesel engines’ preheating and heating requirements. They have a quick preheating time of 5-7 seconds and may start from cold.

5.3 Commercial Vehicles Glow Plugs

Many glow plugs offer a comprehensive assortment of glow plugs designed to fulfill the needs of trucks, vans, and other industrial applications.

  • The Flame Start System (Type GF) provides dependable, convenient, and ecologically friendly cold-starting performance even at low temperatures.
  • Glow plugs (Type GH) for auxiliary heaters for added warmth and comfort, even when it’s freezing outside. Supplemental heaters come in a variety of styles to meet the needs of both gasoline and diesel cars.
  • Type GD glow plugs with a wire filament heating element for older diesel vehicles like tractors, tow trucks, and construction equipment. The glow plugs are resistant to heavy disturbances, and the heating element is a wire filament.

5.4 SRM 

SRM glow plugs are more advanced than regular and quick glow (QGS) glow plugs. Glow plugs with two coils are known as Self-Regulating Metal (SRM). The heating coil is provided at the probe’s tip, while the second (regulatory) coil allows for a rapid warm-up period to temperatures over 900°C.

 It can sustain a high final temperature on its own after attaining the temperature, allowing for longer post-heating times.

#6 Types of Glow Plugs (Based On Temperature)

Glow plugs are of different types based on temperature modulation. They are hot, medium, or cold, depending on their temperature. A few things will determine the sort of glow plugs you require.

  • Gasoline: The ignition point is determined by the proportion of Nitro in your fuel. Because Nitro generates both power and heat, the greater the Nitro percentage, the more relaxed your glow plugs should be.
  • Engine type: conventional engines typically use regular glow plugs, whereas turbo engines frequently require specialty plugs.
  • Engine size: larger engines have more mass and hold more heat than smaller engines, necessitating hotter glow plugs.
  • Acceleration: hot glow plugs encourage better acceleration and idling, which is perfect for slow-accelerating engines. Meanwhile, colder plugs provide more power, which is suitable for warm-running engines.

The uncertainty of weather conditions necessitates a glow plug that can function effectively in various settings and situations. As a result, while acquiring glow plugs, it is critical to purchase from one of the world’s top manufacturers, guarantee reliability under various settings. 

#7 Thermal Performance

Checking the thermal performance of a glow plug is necessary when purchasing one. You’ll never get the most significant result out of your engine unless you have efficient thermal expansion. As a result, keep an eye on the heating system.

Conclusion

Do you know? The Powerstroke 7.3 engine is the first-ever engine to get a Powerstroke name label!

It is so because the engine works on an electronic-based control system that can deliver an output of up to 475 horsepower. The delivery of this engine is so excellent that only the best glow plug can assist its performance. 

We hope that you can find your suitable glow plug for 7.3 Powerstroke after going through our guide and pick the one that suits the best for your engine.
