Will Any Set of Glow Plugs Work in a 6.0 Powerstroke?

No, not any set of glow plugs work in 6.0 Powerstroke because these engines have certain criteria for accessories. These engines use diesel, which needs thorough combustion for greater efficiency. The size of glow plugs is different for these as well, so you have to be considerate of the size. 

Other than this, you need to have a lightweight glow plug for your 6.0 Powerstroke. It helps in taking off additional load from the engine for better fuel economy. Also, it is important to have a set of glow plugs rather than a singular model. This helps in distributing the burden and keeping the performance optimal. 

Why Did These Glow Plugs Make Our List?

Shortlisting glow plugs get hard with so many options on the market. But, we have chosen some of the best ones for our list by looking for the following aspects in them. 


Durability is the most important factor that we consider while choosing glow plugs. Since they have to undergo major wear and tear daily, they should be able to resist damage.

Combustion Power

The primary purpose of glow plugs is to provide more efficient combustion, right? So, we had to look for glow plugs that have a better fuel economy and give your 6.0 Powerstroke the instant boost that it needs. 


Another significant consideration for us was the warranty policy that the manufacturers offered for these products. A longer warranty makes the glow plugs more reliable as the company takes responsibility for them. It also helps in avoiding hassle if the glow plugs need repairs or replacement. 


Affordability was another major concern regarding these glow plugs. They have to be well within the pricing range that average truck owners can afford without any constraints. Thus, we were mindful of the prices of all the units on our list. Only a few of them are somewhat expensive, but their features make up for the extra bucks.

Why it Stands Out to Us

It stands out to us with the dimensions of 7.3 x 4.2 x 0.3 inches. The size is apt for all vehicles that use 6.0 Powerstroke engines. The glow plug is also quite lightweight at 1.41 ounces, which keeps the engine fully functional.

Furthermore, its frame has higher durability and does not get damaged easily. The installation of this glow plug is quick and does not need any extra tools.

What Recent Buyers Report

This glow plugs collection has a shiny and smooth surface that buyers approve of. They found it quite useful as it does not need any lubrication frequently. Buyers also like its features-to-price ratio, which helps them save a lot of money.

Why it Stands Out to Us

This Allmotorparts glow plugs set has eight sleek and modern single pieces in it. They make up for an efficient plug system of the diesel-powered 6.0 Powerstroke engines.

Along with this, there is a self-regulating mechanism in the glow plugs. This helps in preventing the overheating of the components, which results from the electric flow.

What Recent Buyers Report

These glow plugs have blown the minds of buyers with their competitive prices. They found its quality and performance surprisingly better than what they paid for. They also report having a better mileage and engine performance with this set in their engine.

Why it Stands Out to Us

It has caught our eye with the valve cover gasket, which keeps the glow plugs safe from most physical damages. The valve cover gasket protects not only the glow plugs but also the harnesses while in use.

Moreover, their shape suits the structure of the harnesses in 6.0 Powerstroke really well. This helps in quicker replacement of glow plugs while keeping their fitting quite tight. The package also comes with three pre-installed tube seals as well.

Lastly, you can paint them whenever you want as they do not have any waxy polish.

    Why it Stands Out to Us

    It distinguishes itself from us with its reinforced tips that promise better performance and fitting. The direct-fit option helps you get the glow plugs replaced in no time at all. This makes it easier for you to replace them without even going to visit a mechanic.

    Moreover, the glow plug has high compatibility with 6.0 Powerstroke engines. This applies to both their size and working in this type of engine. The glow plugs also hold true to the standards set by OEM.

    Along with this, each set is rigorously tested for any flaws before shipping. This then makes it even more trustworthy for the users and us.

    Bottom Line

    The bottom line on this glow plug is that it provides a maximum performance boost to your engine. The dual coil structure brings additional power to the glow plugs. Its warranty of two years is another impressive feature, so there is hardly anything missing, making it a great investment.

Why it Stands Out to Us

It makes it to our list because of the superior construction of all its elements. They are not durable in terms of structure, but their work is better than other glow plugs.

These glow plugs have a polished surface to keep the corrosion away. This then increases their life even further.

Aspects to Consider Before Buying

To make the most out of your glow plug, you have to invest in the right one. Keeping this in view, we have listed the aspects that you have to consider before making your purchase. 


The size of glow plugs is of customary importance when it comes to 6.0 Powerstroke. They have to be compact and well-sized to avoid any crowding around the engine. They should also be able to fit into the slot for the plugs without any changes to the structure. They should also be lightweight to keep the additional load off the engine. 


While buying a glow plug, you need to look for its compatibility with your 6.0 Powerstroke as well. It helps in avoiding many unfortunate occurrences, especially when you are on the roads. 


You have to be considerate of the material of the glow plug that you are investing in too. Not all materials can withstand the strain that constant driving puts on their structure. Heavy alloy glow plugs are preferred over others because they have greater strength and wear resistance. 

Start-up Speed

Now, it would be pointless to get a glow plug if it does not start your engine quickly. After all, the whole point of it is to minimize the time taken to start the engine. So, you have to go for glow plugs that claim desirable start-up speed. 

How to Change Glow Plugs in a 6.0 Powerstroke

Changing glow plugs can be tricky if you do not know how to do it. So, it is better to seek a mechanic’s help if you do not have prior experience of changing glow plugs. However, if you know your way around engines, here are some steps you need to follow. 

  1. Begin by unclipping the harness in your 6.0 Powerstroke and putting some lubrication in the void.

  2. Then insert the new harness using an OTC tool to make sure it does not break.

  3. Take out all eight of the glow plugs this way and then detach them.

  4. Now insert the new glow plugs in the harness and secure them in place by hand tightening.

These instructions will help you change your 6.0 Powerstroke’s glow plugs quite effectively. You can watch this brief video for a clear demonstration of how to change them. 


Wrapping it all up, glow plugs are an effective way of making sure your 6.0 Powerstroke stays fuel-efficient. They minimize the start-up time and keep the rate of combustion consistent inside the engine. So, you should buy one with the most attractive features and an affordable price. 

People Also Ask

Glow plugs have become quite popular lately, so people with 6.0 Powerstroke are now looking for new ones. This is why they are curious about different factors concerning them. So, we have answered those questions to make sure you do not have any confusion. 

What Are Glow Plugs?

Glow plugs are accessories for diesel engines, which help in starting the vehicle earlier. They cause an effective reduction in the amount of time needed to start combusting fuel in the engine. Thus, they are heating aid devices for engines as they speed up their start-up. 

How Do I Know if My Glow Plugs Are Bad?

The clearest indication of glow plugs going bad is a hard start of the engine. The engine takes longer than usual if there is something wrong with the glow plug. A sharp decrease in fuel efficiency or misfiring in the engine are also signs of bad glow plugs. 

How Many Glow Plugs Are in A 6.0 Powerstroke?

A 6.0 Powerstroke has eight cylinders in it, each of which uses a single glow plug. So, in total, eight glow plugs are required to increase the speed of starting up a 6.0 Powerstroke engine. 

Should I Replace All Glow Plugs?

Yes, it is important to change all the glow plugs while you are at it. Having even a single faulty unit can damage all the other ones. So, it is important to change all of them at once to avoid any worries later on. 

How Much Does it Cost to Replace Glow Plugs?

Glow plugs do not cost much on their own. Most of them fall within the pricing range of $25 to $50. And in order to get them fixed, you need to pay $100 to $200 to a mechanic if you do not know how to do it.

How Often Do Glow Plugs Need to Be Replaced?

Glow plugs keep working for quite a long time. They usually last up to 100,000 miles while keeping up with the daily wear and tear. Another good thing is that they are quite cost-effective, so replacing them is not a strain on your budget. 

What's the Difference Between Spark Plugs and Glow Plugs?

Both spark and glow plugs serve the same purpose of helping with starting the engine. However, they are different in terms of the type of engine they are used for. Glow plugs work well in diesel engines while gas engines use spark plugs. 

Are Glow Plugs the Same as Injectors?

No, glow plugs and fuel injectors have entirely different kinds of structure and function. The former speed up the ignition, whereas the latter sprays fuel into the engine.
