The Cummins 6.7 is one of the most popular engines out there among truck enthusiasts because this diesel engine has consistently proven its worth. It was introduced to Dodge Ram/Ram trucks in 2007, and since then has been a solid engine. Dodge and Cummins have been partners for more than 30 years, and the engine shows why the partnership has worked. The latest iterations of the engine boast up to 400 hp and 1000 lb-ft and are lighter but stronger than before. But maybe you want more? Let’s look at the Best 6.7 Cummins Upgrades:

2. Best Tuner for 6.7 Cummins – Edge Products Juice w/Attitude CTS2
What does a tuner do? Think of it as a simple-looking-yet-complex device that can improve everything your vehicle does. A good tuner can enable the use of certain modified/aftermarket parts, while even simple tuners can let you tinker with the engine’s performance. You can also check, in real-time, what’s going on inside the truck, and clear error codes, if any.
[If you want to learn more about tuners, read our Ultimate Guide to Tuners, Programmers, and Chips.]
With a good real-time display (Attitude CTS2), the Edge Products Juice is one device that does it all. The internet-updatable tuner comes with a range of power maps, a shift-on-the-fly feature, and you can unlock up to 150 hp and 350 lb-ft of additional power and torque.
Includes a feature-rich touchscreen
But that’s not all. The Juice tuner comes equipped with a nice selection of essential features. For instance, it has cold-engine protection, backdowns, turbo timer, and more. You can also go back to the factory tune if you need to take your vehicle back to the dealership. Its touchscreen interface also makes life very easy — it dims automatically when the ambient light is low, comes with customization options, and has a high-resolution display.
Why do we like it?
It’s hard to find a better alternative to the Edge Products Juice w/Attitude CTS2 because it does everything so well. You’d need to contact the seller about warranty whereas the compatibility is listed to be for 2013 – 2018 Ram 2500/3500 trucks. And yes, it’s CARB exempt as well!

3. Best Delete Kit for 6.7 Cummins – Sinister Diesel EGR Cooler Kit
No products found.
By ‘deleting’ a truck, you can remove some of its pollution-control components —and in theory, open it up to better performance. Legally speaking, deleted trucks aren’t meant for on-road/highway usage. You’ll run into some issues with law enforcement if you drive a deleted truck on public roads.
The Sinister Diesel EGR Cooler Kit’s well-made, pressure-tested components enable it to perform better and longer. The kit helps recirculate engine coolant faster than the stock setup, cooling the engine faster. (Makes sense, right?) At the same time, the kit also ensures that sooty fumes aren’t interfering with the engine.
The Sinister Diesel EGR Cooler Kit is made for the Dodge Ram 2500 and 3500 pickup trucks (both come with the 6.7 Cummins engine) made during the model years 2010 – 2016. The kit is said to be durable and offers leak-free service. Its great build is made of nickel-plated steel and machined billet aluminum.
Why do we like it?
The Sinister Diesel EGR Cooler Kit can be a good addition to your off-road-only truck. You’ll need to get in touch with the seller for information about the warranty. Overall, users have been happy with it.

4. Best Cold Air Intake for 6.7 Cummins – S&B Filters Cold Air Intake for Dodge Cummins 6.7L
- 54.6% More Airflow & 99.55% Efficiency Rating. Tested To The Internationally Accepted ISO 5011 Standard
- Designed To Avoid Check Engine Lights
- Premium Silicone Parts Last Longer And Look Better
- S&B utilizes robotics to precisely apply the correct amount of oil to your filter before it ships. Oil Amount: 72 Grams on Filter Element. Replacement Filter: KF-1037 & Filter Wrap: WF-1037
- Street Legal in All US States, CARB Exempt ID: D-590-19
With the 6.7 Cummins diesel engine, a cold air intake will usually make the engine perform better because it can bring in more oxygen-rich air and therefore improve combustion. Along with that, the intake kit also houses the air filter, which cleans the air entering the engine. So while it’s important to get large amounts of colder air, it’s also necessary to ensure that the intake kit has a good filter and corresponding housing for that.
A cold air intake will just increase the performance and the responsiveness of the engine, but a good one will also ensure that the filter isn’t too exposed to the elements — offering a complete solution. The S&B Filters choice comes with a fully closed airbox. That ensures the air entering the engine is cleaner and the filter doesn’t die prematurely.
Cotton cleanable filter
To improve the airflow, the S&B Filters product has a dual-inlet airflow. The overall increase in airflow after installing this is 54.6 percent whereas the efficiency rating is 99.55 percent. In addition to this, the cold air intake kit is less likely to throw a check engine light your way. It comes with a cotton cleanable filter and long-lasting silicone parts.
Why do we like it?
What’s appealing with the S&B Filters intake kit is the presence of dual-inlet airflow, which wil help the engine breathe freely. The overall good quality of the product is backed by a fully closed airbox that protects the filter from the elements. The cold air intake kit is compatible with the 2013 – 2018 Ram 2500 and 3500 trucks. It’s also CARB-exempt, takes about 2 hours to install, and is enjoyed by its users across the USA and beyond.

5. Best Fuel Filter for 6.7 Cummins – Mopar Dodge Ram 6.7 Liter Diesel Fuel Filter + Water Separator
- Standard Replacement Oil Filter
- It offers dependability and reliability that meets the OEM oil filtration specifications.
- It has a fluted shell that simplifies removal from underneath.
- It contains Cellulose Filter Media for containment removal.
For an engine to perform well, it must get clean fuel — not only for good combustion and lubrication but because in the presence of impurities, the engine can suffer from catastrophic damage. A good fuel filter doesn’t let that happen by cleaning the fuel that goes into the system. It can get worse if you live where finding clean diesel is problematic or in harsher cold environments. In the case of extreme cold temperatures, the contaminants (even something as simple as water in the fuel) can cause engine failures — because of the inability of diesel to reach the engine due to freezing.
It’s easy to look at other third party alternatives because with those you might be able to save a few bucks. But the issue is a lot of third-party choices don’t follow the factory specs closely. In the case of filters, filtration and particle size need to be followed perfectly. The Mopar-branded, factory filter does exactly that.
Water Separator included
The set includes a fuel filter and a water separator. It’s compatible with 2013 – 2018 6.7 Cummins engined RAM trucks. The water separator is located in the middle of the truck whereas the fuel filter is under the hood.
Why do we like it?
It’s okay to stick to the factory component in the case of a fuel filter because there won’t be any noticeable performance gains by putting in an aftermarket filter. But it’s also fine because the component is made in line with the specifications/requirements of the particular truck model you’re driving. You’ll need to check with the seller about the warranty on this.

6. Best Exhaust for 6.7 Cummins – MVP Performance Racing 5” exhaust for 6.7 Cummins
No products found.
The objective behind upgrading an exhaust system isn’t only to make the truck sound better, but also to make it more responsive. Depending on the application, you can look at exhaust systems that are very loud or if you’re going to drive the truck regularly on public roads, something that has a reasonable sound and low in-cabin droning. For the 6.7 Cummins, there are a few good choices in the aftermarket exhaust section, and here’s the best one according to us. You can read the entire article about exhausts through the link at the end of this description.
Made of aluminized steel, the MVP Auto Parts Performance Racing exhaust system is compatible with a variety of Dodge Ram/Ram variants — more detail on that below. It’s a 5-inch exhaust that has dual turbo-back + downpipe included in the kit. It’s got a mandrel-bent tubing for consistent and maximum flow. There’s no muffler or tip included, and it’s a straight-pipe design.
Made for a variety of models
The listing mentions that you’ll need to relocate the spare tire to install this. It fits the models with the HE351VE turbocharger, so keep that in mind in case you’ve upgraded the turbo to a non-stock unit. According to the seller, the model is made for the 2013 – 2017 Ram 2500 and Ram 3500 trucks. The Air Ride Suspension models, as well as those with middle-mounted shocks, aren’t compatible. But on the bright side, Extended & Crew Cab, Short Bed, and Long Bed ones are compatible. In certain cases, though, the extension pipe may be required to be trimmed.
Why do we like it?
We’d strongly suggest checking with the seller about the warranty as well as the compatibility with this. This is to ensure that you get the exact part that’s made for your truck. Aluminized steel isn’t the best material out there but with it, you get to save some money.

7. Best Oil Filter for 6.7 Cummins – Fleetguard Oil Filter for Dodge Ram Cummins
- Largest OD 93.47 mm (3.68 in)
- Overall Height 176.28 mm (6.94 in)
- Thread Size 1-16 UN-2B
- LF16035 for Dodge Ram with Cummins Diesel Engine
The oil filter’s job is to ensure that the engine gets clean oil for lubrication. In the absence of a filter, the engine can suffer some irreversible damage, eventually leading to negative effects on performance and engine life. Since the 6.7 Cummins is known to last long, don’t skip on maintaining this small component.
This is a factory-spec filter for the 6.7 Cummins engine. Apart from the fact that it’s made exactly for the 6.7 Cummins (and isn’t a universal product made to fit the engine), it has a 100 percent 30-micron efficiency.
Compatible with 2007.5 model year onwards
The Fleetguard filter enjoys a great reputation because it works exactly the way it’s supposed to. It is 6.945 inches tall and fits perfectly. It’s compatible with 2007.5 – 2018 models of Dodge Ram/Ram trucks with the 6.7 Cummins engine
Why do we like it?
It’s safe to stick to the OEM/factory replacement product in the case of the oil filter because it does the job well. Users and truck enthusiasts have liked the Fleetguard product because of that reason. You’ll need to check with the seller about finer compatibility and warranty.

For the Best Tuner for 6.7 Cummins, we chose the Edge Products Juice w/Attitude CTS2 because it’s a fantastic 2-in-1 device. It doesn’t just let you add custom tunes to your truck, but also allows real-time monitoring of how well the truck is performing.
The Best Delete Kit for 6.7 Cummins is the Sinister Diesel EGR Cooler Kit. If you’re planning to take your truck away from public roads, this is one good product. It opens up the engine in a lot of ways, and so helps it produce more power — and even live longer.
The S&B Filters Cold Air Intake for Dodge Cummins 6.7L is our choice for the Best Cold Air Intake for 6.7 Cummins. Its dual air inlet, fully enclosed airbox and an overall good build just make it easy for us to choose this over others.
The Best Exhaust for 6.7 Cummins is the MVP Performance Race 5” exhaust for 6.7 Cummins. It’s made of aluminized steel (which keeps the price low) but sounds good.
For the filters, we’ve stuck to the factory choices for both oil and fuel filters. That’s because both the Fleetguard Oil Filter for Dodge Ram Cummins and Mopar Dodge Ram 6.7 Liter Diesel Fuel Filter + Water Separator don’t cost much and are made with the exact specifications — something you can’t be sure with aftermarket units.
