Now that you are well informed about each product in brief. Get to know the pertinent aspects you should prioritize as you proceed to choose the best tool. This detailed buyer’s guide will lead you to make a creative choice as you proceed to acquire your glow plug.

Below are the crucial factors to consider when making a purchase decision for the best glow plugs for 6.0 Powerstroke.


Often, most people disregard this aspect, whereas it is very critical. You might not understand that not all materials can resist the strain that continual driving imposes on their structures.

Mostly, hefty alloy glow plugs are recommended due to their outstanding strength and wear resistance. Therefore, it is paramount to choose a model based on the quality of components used to make it.


Unfortunately, purchasing a glow plug that does not start your engine conveniently is a terrible recipe. The main reason for this item is to lessen the duration taken to commence the engine. Thus, you have to choose a model that asserts moderate start-up speed.

Closeness to most brands

Since this is a significant concern, you have to go for a product that will adapt your 6.0 Powerstroke easily. By doing so, it will help you to avoid some bad events while on the road. That is why it is such a good idea to look up to this issue as you plan to get one glow plug.

Symptoms of a bad Glow Plug

Determining a lousy glow plug due for replacement is an essential practice that can help you big time before your diesel engines fail you at the hour of need. Most of the glow plugs I have reviewed in this article are durable and reliable. However, in the end, these plugs may be susceptible to wear and tear. Thus, it is crucial to determine when the plugs are due for replacements.

Below are primary signs that your glow plugs are due for replacement.

Hard Starting

Perhaps, the most common indicator of damaged glow plugs is a hard starting engine. The combustion engine may not attain the required temperature to ignite the fuel and start the engine in cold conditions. This happens when your car engine’s glow plugs malfunction. In such an instance, check whether there are issues with the fuel or battery. However, if the battery and the fuel have no problems, the issue lies with the glow plugs.

Misfiring of the Engine

Regardless of the vehicle, you are using, the diesel engines’ combustion process always requires high comprehension. As the vehicle owner, you must ensure that the fuel you inject is of the correct amount and done at the right time, as this is important to establish the ignition and hence the beginning of the combustion process.  However, if this is not done. Misfiring may occur. The diesel engine’s misfiring is associated with compression pressure, fuel quality, and fuel injection, all, which influence fuel combustion.

For the ignition to occur, the combustion chamber’s heat should reach up to 232 degrees Celsius. The heat comes from the glow plugs and the pressure from compression. This explains the reason for warming up the glow plugs for effective starting of the diesel engines. However, if an individual uses faulty glow plugs, the engine chamber temperatures will not be attained, which results in misfiring engines.

Reduced Fuel Efficiency

The second essential element of consideration is the reduced efficiency of the fuel. The temperature and individual quality of the fuel determine the fuel efficiency, though the glow plugs have specific significant impacts on fuel efficiency.

The freezing point of the fuel can be reduced by the local climate, resulting in the diesel being blended with certain additives during the cold periods.  The additives reduce the energy contents of the fuel and its efficiency.

It is important to adjust the engine’s operating temperatures to ensure complete combustion of the injected fuel in cold conditions, and this is where the glow plugs come in.  The glow plugs effectively add the extra heat in the combustion chamber and guarantee that the added fuel is wholly burnt for engine ignition.

However, suppose the glow plugs are faulty, the needed temperature will not be reached. This weakens the engine’s performance and will involve straining the engine capabilities to satisfy the road demands, adversely affecting the fuel efficiency of the vehicle.

White Smoke

The incomplete combustion in the diesel engine always results in the production of white smoke. The unburnt fuel particles travel through the tailpipe as smoke.

During the engine startup, the white smoke production can be because of the faulty glow plugs. Other reasons for the production of the white smoke in the diesel engine can be low engine cranking speed, air presence in the engine system, and low compression.

However, suppose there is tenaciousness of the white smoke even after the engine’s warming up, other factors may be involved. It may result from one or two injectors from the engine, a worn-out injection pump, or retarded injection timing. Thus, the presence of white smoke from the engine should be an alarm to a visit to a garage for the replacements of the glow plugs and other maintenance practices, especially when there is the persistence of the white smoke after warming up the engine.

Rough Idling

Over time, your glow plugs can get burned out, damaged, or carbon fueled.  Either of these will enhance the difficulty in starting your engine, especially with the decrease in temperature. It may roughly idle and produce white smoke from its exhaust for minutes when it starts.  Always check the tips of your glue plugs and determine whether they are burned. Also, you should check the fuel injection timing to help address the problem of rough idling.

Black Smoke

The air-fuel ratio imbalance in your car’s engine can produce black smoke, particularly when too much engine and less air.  The production of the black smoke implies inadequate or incomplete combustion of the fuel.

The faulty glow plugs can hinder the diesel combustion process, resulting in the production of black smoke from the engine through a tailpipe. The aspect should be a warning that something is wrong with your glow plugs or other important parts involved in the combustion process.

Frequently Asked Questions

The utilization of the best Glow Plugs for 6.0 Power stroke is attached to various issues that the buyers always seek their clarifications before they settle on a given unit. The questions are vital as they help with the decision-making before and after the purchase. Below are some of the most crucial questions that individuals always seek to ask.

How Long To Let Glow Plugs Warm-Up?

The glow plugs take at least 15 seconds to warm up, depending on the external temperature. In cases when the temperatures are too freezing, your glow plugs can take longer to warm up.

Will a 6.0 start without glow plugs?

Yes.  The primary role of glow plugs is to aid in heating the motor’s top end to guarantee an easy start. However, once the motor has started, it can run without the glow plugs. Thus, glow plugs are vital as elements that enhance the ease of start of the unit. The mechanism is the same as those of the older manual cars where you could pull-start and not require a starter to run the motor. It is, thus, possible to start a 6.0 without the glow plug. The glow plugs are added for efficiency and convenience.

What will happen if you do not let glow plugs warm-up?

Even if you do not let your glow plug warm-up, most diesel will still start even if they are cold. There is a possibility that even without waiting for your glow plug to heat up, it must have caught some small heat to facilitate the starting of your engine. However, in some cases, if the glow plugs are not warm, the vehicle may fail to start.  In that case, if you have a high amount of fuel in your cylinder, you may end up flooding the engine that may prevent the car from starting immediately.

What Causes Glow Plugs To Burn Out?

Your car’s glow plugs can burn out when excessive heating is caused by carbon build-up. To prevent the glow plug burn-out, ensure that you apply the right carbon reamer during glow plugs installation.

Why do diesel engines need glow plugs?

Diesel engines require glow plugs to help provide extra energy to start the engine.  The high-speed diesel engines in the cold weather may prove a tall order to start due to the ignition system’s interference with the cold contact. The ignition may be prevented when the cylinder head absorbs the heat of compression or the high mass in the cylinder, blocking the engine from starting.

How often should you change your glow plugs in a diesel?

The glow plugs in a diesel should be changed after 100,000miles. The practice implies that changing the glow plugs is not an aspect you will have to worry about often. However, the illustration also does not mean the plugs may not fail before reaching the 100,000 miles mark, especially if you often hard start or utilize lower quality plugs that are not ideal or recommended for your pickup.

 Can Faulty Glow Plugs Drain The Battery?

Yes. Faulty glow plugs use more power to reach optimum performance, hence draining the batteries faster. However, even with this consumption, the glow plugs will not reach their peak operation despite the high energy consumption or battery use.

Can A Diesel Start Without Glow Plugs?

Yes. It is possible to start a diesel engine without glow plugs. However, you will experience a challenge starting the diesel engines in cold or freezing weather if they lack glow plugs. The glow plugs help you heat or warm up the diesel engines during the cold or freezing weather, allowing a fast or easy start.


Having basic knowledge at a fundamental level is the only remedy that will help you find the best glow plug. We have seen how valuable these devices are and the significant impact they enact on an engine. These units are highly dependable to deliver demanding results. And it’s the only means of upgrading your engine’s start-up performance.
