OEM, Refurbished and Remanufactured Injectors

OEM, Refurbished and Remanufactured: Know the Difference

Diesel Fuel Injector ExampleWhen shopping for injectors it is important to know the difference between common industry lingo regarding the condition of the injector in question. Used, Refurbished, Reconditioned, Rebuilt, Remanufactured all mean different things. Not educating yourself on the difference can ultimately cost you time and money. The information below should help educate you on the difference:

New Injectors

New injectors are straight from the factory and have never been used. These injectors typically come from Bosch, Delphi, Cummins, CAT or GM. They usually come with a dealer 2-3 year warranty and certificate of authentication.

OEM Injectors

OEM InectorsOEM Injectors are used injectors that are completely dissembled examined by quality control then completely rebuilt from the ground up. The rebuild process is completed using new and updated components and focuses on replacement of all seals, valves, plungers, solenoids and injector nozzles. Everything is replaced Diesel Fuel Injectors Multipleexcept the injector body/housing which is either plastic, steel or carbon fiber. The newly rebuilt injector is then tested by the original manufacturer not a 3rd party rebuilder. Bosch, Delphi, Cummins etc… conduct these tests and rebuild processes.

Refurbished/Used Injectors

Refurbished or used injectors have been removed from running diesel engines. They are not rebuilt but rather cleaned internally and externally and inspected to make sure they still meet or exceed the original OEM standards. If the injector is still in good running condition it is tagged as Refurbished and sold at a cheaper rate simply because they are indeed used. The vast majority of Diesel Fuel Injectorsrefurbished injectors still come with a 1 year warranty which make them a great deal for those looking for a bargain.

Remanufactured Injectors

InjectorsRemanufactured fuel injectors differ from Refurbished injectors in that they have been completely torn down, examined and tested for wear and then remanufactured using brand new components. This is where most customers get confused. Remanufactured injectors can be rebuilt with used parts or remanufactured but not to OEM spec. All of our remanufactured injectors are remaned to OEM specifications using new or 100% reman parts. If you don’t purchase injectors with us make sure you ask your injector sales rep if the reman injectors are to OEM spec and if they offer a warranty. Capital Reman always stands behind its work and warranty.

Replacing an injector is not always due to leisure purposes. This statement is especially true for vehicles with the 5.9 Cummins common rail engine.

It is not without its injector issues, which tend to break frequently. This renders them completely useless. Getting a replacement is a challenging task. Then the question arises, whether to buy a brand new one or a remanufactured one.

So, I have compiled a list of the best injectors for 5.9 Cummins common rail, which are guaranteed not to have the issues present in the preinstalled one.

So, without any further ado, let’s get straight into it.

5 Top Best 5.9 Cummins Common Rail Injectors Comparison

1. Dodge Cummins 5.9L Injector

Here we go; starting strong is the injector for the common rail by the brand NMN Precision. It is available for both the Dodge Ram 2500 and 3500, which have the 5.9L common rail engine. This Dodge Cummins 5.9L Injector has an OEM fit.

What this means is that there will be no extra tools or requirements to install it. They clearly state that their product meets or exceeds OEM specifications. Well, let me be the judge of that.

The manufacturer guarantees that their product has been prepared with the utmost precision, hence the name NMN Precision.

They vouch for their product and state that there will be no problems such as leakages or failure after short usage. So, you can rest assured that at least they won’t be the ones to create issues with your vehicle.

You can rest assured that all your engine misfiring problems, creating a lot of smoke, and giving you poor fuel efficiency all have been ironed out.

You will be provided the experience which Ford fails to give you when you buy a new one. They also don’t require a core charge. You don’t have to ship your old injector in to get a refund. They will not ask for it.

Moreover, the injector comes with a 2-year warranty. This means that if the product arrives with a fault or a manufacturing defect is noticed during the time mentioned earlier, you are eligible for a free-cost replacement.

Some people received units that failed within a month. That is surprising because of the bold claims of the brand that there will be no faults. But, all of those users were refunded without any hassle.


  • Has an OEM fit
  • 2-year warranty
  • No core charge
  • Better fuel efficiency


  • Units failing after short usage

The brand assumes responsibility when its products break. And for me, that is a big plus. The positive reviews of the injector outmatched the negative ones. So, you can rest assured that you will receive a unit which will satisfy your needs for a long time.

2. Bosch Common Rail Injector

Well, here we have a product from a brand which is renowned worldwide for this extremely high-quality auto parts. Even I regard the manufacturer so much that I was surprised when NMN Precision could overtake it for the number one spot on my article.

One main reason for them to earn the second spot is that these Bosch Common Rail Injectors have been remanufactured. This means that instead of being new, the brand buys back problematic ones, reinforces the build, and irons out all problems to create a product that matches OEM requirements.

You will notice many improvements and gains, such as a better idle RPM, better fuel consumption, increased horsepower, and unmatched reliability. This is what Bosch is all about. Customer care is their top priority. And let me tell you, they do deliver on their promise.

The product also comes with all the required stuff for installation, such as O-rings and washers. The brand also recommends replacing the connector tubes for the injector to avoid contamination. Now, you don’t want your new one to get dirty and create problems for you.

Lastly, the manufacturer has tested these injectors with exact OEM specifications. They have been tested to handle extreme usage for long amounts of time. So, you can rest assured that these, unlike the original ones, will not break on you.

The only problem with Bosch products that they are priced higher than the competition. The same is the case with this common rail engine.


  • Meet OEM specifications
  • Tested according to OEM requirements
  • 2-year warranty
  • It comes with O-rings and washers

The only thing that may deter buyers from buying these is that they have been priced higher than usual. If you agree to spend on this one, then you will not regret this decision at all. You also are provided with a warranty in case you receive a faulty unit.

3. HX Diesel Injector For Cummins 5.9L

Taking up the third spot on this highly competitive list is an Injector by the Brand HX. Now, I know you most probably may not have heard of this name before.

But, let me tell you, don’t judge them for their poor marketing. They make stellar injectors which did not only leave customers impressed but reviewers such as me too.

This buy is for six fuel injectors instead of one. This means that you get to replace all of them on your vehicle, so there will not be any fuel injection issues. You will notice improved fuel efficiency because they regulate the spray of fuel into their engine in a much better way than the original ones.

That can be seen because the tolerance of flow is 2% on these, rather than 5% on the stock ones. I don’t know about you, but that is a pretty huge difference. These injectors have been tested to ensure they meet strict OEM specifications and testing requirements.

You can rest assured that there will not be any leaking, cracking, or eroding of the product. These are all issues present in the stock ones. They have been tested using Bosch’s test bench of 815 operations.

They have also been tested under eight real-life conditions. These are also Bosch remanufactured. So, you are getting the excellent product there is on the market. They also come with new nozzles and control valves from Bosch themselves.

The only main drawback is that the warranty period is very less. You are getting a warranty of only three months or 5000 miles, whichever comes first. The time period is less for any faults to appear, making it tough to ensure the injector is fault-free.


  • Strict OEM testing
  • 3% better flow tolerance than the stock ones
  • Bosch remanufactured ones


  • Three months / 5000-mile warranty

Although I did not come across any review stating that there were issues with this one, the warranty period is too less to test the injector entirely. Other than that, it is an excellent product and surely deserves a spot on this article.

4. Diesel Care 5.9L Common Rail Rebuilt Injector

Although this list is short, the competition on it is extremely close. Coming in fourth place is Diesel Care 5.9L Common Rail Rebuilt Injector, which is yet again a remanufactured one.

To my surprise, people prefer rebuilt ones over new ones, not only due to the savings in terms of money but due to the more than similar performance between the two.

So, why not save a ton of money and buy a used one guaranteed to get you better than stock performance?

The first main thing to know is that this product does have a core charge. This means that you are also paying a charge that may or may not be refunded to you when you send your old injector back on top of the product’s actual price.

The refund amount depends on the condition of the sent product. If it is cosmetically as good as new, you will get the seller’s full amount specified. If it is worse, then you may receive a partial or no refund at all.

Bosch originally manufactured these rebuilt ones. This means that you are getting a top-of-the-line injector that any other product cannot beat on the market.

The brand gets its hands on such injectors using its core policy. They have been rebuilt to ensure all problems present in the original ones are cleared out to make a near to perfect product.

Futhermore, the company ensures that you will get the highest quality products that have been rigorously tested according to OEM standards. This ensures that the injector which consumers receive is completely defect-free.

They also come with a one-year warranty which is lesser than most of the options out there. One year is more than plenty of time for any issues or faults to appear.

You are eligible for a free-cost replacement, repair, or a full refund on the rare occasion that they do. All of you have to make sure is that the fault was not due to your usage and a fault that originated from the factory.

The only drawback, which is not a drawback, is that this tuner comes with a one-year warranty. It is half of most of the other options.


  • Meets OEM specifications
  • Manufactured by Bosch
  • Better fuel mileage and horsepower


  • Core charge
  • One-year warranty

This product is one you must consider before deciding to buy a new injector for your engine. It is extremely durable and rebuilt to ensure it will reach the specifications and requirements that the original ones failed to do.

5. Labwork 6X Diesel Fuel Injectors

Finally, coming up in the fifth and final position are the 6X Diesel Fuel Injectors by Labwork. Let me inform you about one thing. Although this one scored that last place, it most definitely not the least.

These five were chosen from a list of many who claimed to be superior to the others. So, I took the task of deciding which one’s claims hold. As it turns out, Labwork is one brand that did not advertise its product falsely.

This buy gives you six injectors instead of one. So, within one package, you are getting all the ones you need to replace.

By replacing all of them, you will be sure that all the injectors you have to perform equally and without any issues. You also don’t have to worry about any old ones creating any issues for you in the future.

The brand also does not have a core charge. That means there is no extra charge for the core. You can keep the old one and won’t have to worry about getting any refunds later on. Users mostly had positive reviews because it has been rebuilt to ensure you won’t encounter any problems due to strict testing.

You will notice a considerable boost in not only the fuel mileage but the performance as well. The reason for that is you are getting better fuel spraying which is efficient. The perfect combustion in the engine then leads to better performance.

Users had major problems with these. The first main issue was that the packaging was of extremely poor quality. The protective caps were not even installed on them. Some reviews also stated that their vehicle hard started after installing it.


  • Meets OEM specifications
  • Better fuel mileage
  • Better performance


  • Hard starting issue
  • Protective fuel caps not installed

There is a reason the brand scored the last place on this article. Although it was better than many other options on the market, it still did not please many customers because they were carelessly packaged and had some issues.


This short FAQs will focus on potential buyers’ common questions and sheds light on people’s issues.

You Listed New One And Several Rebuilt Ones. Which One Do You Prefer?

I would prefer a new set of injectors rather than remanufactured ones. The reason for that is there is no chance that you will get a product that may have some issues unresolved while remaking it again.

You are also getting a two-year warranty in the case of the NMN Precision injector. But, if you are looking for something on a smaller budget, you can buy a rebuilt one.

The chance of it failing is higher than a new one, but I would recommend buying one from this list. And most definitely do not buy alternatives that are cheap and claim to be new. They always have some problems.

Many Manufacturers Are Listing In Sets Of Six, But I Need Only One. Why Is That?

First of all, some manufacturers do sell single injectors. But to get the most out of your engine, it is always recommended to replace all four. Let’s take an example. After using your car for 50000 miles, you get a tire issue. Will you replace only one or all of them? The same can be said for shocks too.

Unless you replace all of them, you will most likely experience unreliability due to mismatching components. Some may inject more fuel than others, which may lead to unreliable accelerating. This is the reason it is recommended to replace all six instead of only one fuel injector.

Is Having A Core Charge A Benefit Or A Drawback?

In the case of a core policy, each person has his view. Although you are getting a rebate for sending your old injector back in, I would avoid such a hassle.

The old part may break during shipping, which may or may not be eligible for a refund. You also have to send it within a specific period of time, or else the policy becomes invalid, or you may not be offered back the full amount promised.

If you are getting a core charge, I would want to ensure the brand honors its policy by checking out other customers’ reviews. Even if they do not, then you can decide not to send it or take a risk. You are already saving a lot by getting a rebuilt one!

My New Injector Is Producing A Lot Of Smoke And Is Giving Me Worse Fuel Efficiency. What Should I Do?

The most probable reason for this is that you have received a faulty unit. All of the above injectors have a warranty. Although some do have a lesser period, if the fault appears within the warranty period, you can get a refund or a free replacement.

If you do face such an issue, don’t hesitate while contacting the brands. All of the five brands listed above have had no problems related to warranty claims.


The arguments never stop whether to buy a new or rebuilt one. The following buying guide will help clear up that confusion. What I can say is that a new injector will surely upgrade over your original one.

Even if you don’t have any issues with the preinstalled one, I would recommend spending a bit of money on getting them replaced.

This way, you can be sure that there will be no issues in the future. On this list of the best injectors for 5.9L Cummins common rail, I would without any doubt recommend the number one product, the Dodge Cummins 5.9L Injector.

It is brand new and has the highest number of positive reviews. It has been designed with extreme precision.
