Best Cold Air Intake for 6.7 Cummins
S&B Filters 75-5092 Cold Air Intake Filter
Here is an intake kit that straightens air flow and minimizes air restrictions. Its straightforward design ensures that your engine receives 51.68% more airflow than it does from the stock intake. That allows the engine to churn out an efficiency rating of 99.50%.
You have no choice but to accept S&B’s claim that this intake kit lasts longer than its competitors. Wondering why that would be the case? That is because this cold air intake kit has been tested to internationally accepted ISO 5011 standard. It’s like a seal of expert approval for this model.
It is made of premium silicone and has just the right amount of oil that helps the built-in air filter trap incoming dirt and dust particles. The 90 grams of oil that are visible on the filter element won’t need any replacement for up to 100,000 miles. That’s at least a year worth of hassle-free filtration.
To further sweeten the deal, this model comes with a MAF (Mass Air Flow) sensor. It empowers the cold air intake to keep the check engine light off. Also on offer is a secondary outlet that provides improved airflow by minimizing the restriction in the route of the incoming air.
Pros
- Has a Mass Air Flow sensor
- Equipped with a secondary air outlet
- Can withstand temperatures up to 400*F
Cons
- Little slack in factory wiring harness
S&B Filters 75-5092D Cold Air Intake Filter
Thinking that we are recommending the same product twice? Think again. It isn’t only the name of the 75-5092D cold air intake filter that is different from the 75-5092 mentioned above. There are multiple features that separate both these units. Let us compare both the models to explain this point.
While the previous model allowed 55% more airflow to the engine, this one lets in 49.77% more air. It doesn’t use any oil to trap the incoming particles either. Instead this air intake uses a dry filter gauze to trap dust particles and prevent them from harming the engine.
Everything else of this model is similar to the one you saw above. It is also tested to ISO 5011 standard, has a premium silicone construction that lasts longer and looks better, and allows your engine to boost an efficiency rating of up to 99.20%.
S&B devoted quite some time to engineer their intakes so that your engine can easily run them without requiring any enhanced tuning or stock calibration. It has also provided this model with a signature clear lead as well as a custom enclosure that keeps out unwanted engine heat.
Pros
- Premium silicone construction
- Custom enclosure keeps unwanted engine heat out
- Ensures less restrictive air flow
Cons
- Have to drill to use the plastic hole
BETTERCLOUD Cold Air Intake Kit
Everything about this cold air intake kit oozes durability. You only have to look at its construction to believe in this claim. Its manufacturer has used CNC mandrel bent aluminum tube for the intake, thereby ensuring smooth and restriction-free flow of air and years of usage.
The gloss black finish of this air intake kit makes it a perfect candidate to complement other parts underneath your hood. All the mounting brackets, bolts and hardware that you’d need for installation are included in this package. You won’t have to buy anything extra to assemble it.
Yet another strong point of this model is its reusable washable filter. That is beneficial because you won’t have to replace the filter the moment its performance goes south. All you have to do is take it, blow the embedded air with compressed air and re-install it.
Unfortunately, its limited compatibility leaves something to be desired. Most models you see in this review work with almost all the latest models that use 6.7 Cummins engine. Not this one. It is only compatible with 2007.5 to 2012 Dodge Ram 6.7L Cummins Diesel vehicles.
Pros
- 4’’ Aluminum construction

Volant 151536 PowerCore Cool Air Intake
Next up on our list is this easy-to-install and heavy-duty intake kit. Its polyethylene construction helps this model withstand external elements. What it also does is prevent the vibrations emanating from the engine disturb the intake kit. That’s precisely the reason why it lasts as long as it does.
One of the defining features of this model has to be its filter’s ability to meet OEM standards. Most cold air intake kits come with filters that require you to wiggle them into the box. Not this one. Its OEM filter will go into its place in your engine like a hand goes into a glove.
Although there is one area where this model is similar to most cold air intakes on the market. It is designed at an angle that directs the airflow at the engine to help it provide proper horsepower while remaining cool at the same time.
Unfortunately, its usage of a PowerCore dry element filter comes as a double-edged sword. On the one end, the dry filter requires minimal maintenance and has helped keep this kit’s asking price low. On the other, it has a low shelf-life, especially when you compare that with wet element filters.
Pros
- Filter meets OEM standard
- Ensures outstanding direct airflow
- Improves the efficiency of the engine
Cons
- Dry filter has slightly reduced shelf life
Sinister Diesel Cold Air Intake for 2007.5 – 20012 6.7L Cummins

FAQs
Here’s the criterion we used to select the cold air intake for 6.7 Cummins:
Q: What is the style of the cold air intake?
A: Whether you’re purchasing them from your local store or browsing Amazon in search of a better deal, you’d see that cold air intakes are available in two styles. They are either available in “short ram” style or you can get them in “true” cold air intake version. Here’s how both these styles differ.
- Short Ram System
This system is manufactured to replace your stock intake with an open element air filter and a new pipe. It costs less than true cold air intake version and is relatively easier to install.
That’s where the plus points of this system end. Since they do not move the location from where the engine pulls in air, they allow engine heat an easier path into the system
Experts might tell you the drawbacks of this arrangement. It results in the engine producing considerably less horsepower and torque than a true cold air intake system.
- True Cold Air Intake System
Similar to the short ram system we discussed above, they too are meant to replace your stock intake. But the similarities between both end right there. Here’s why we’re saying that.
True cold air intake system, unlike their short ram counterparts, extend their pipe as far away from the engine as possible. This helps them suck air that is hovering outside the engine bay.
Since this air is much cooler and denser than the air that is inside the hood, it is more oxygen-rich. This allows it to increase combustion efficiency and help produce more torque and horsepower.
Q: Does it offer universal or direct fitment?
A: Once you have decided in favor of a true cold air intake, you’d be faced with another dilemma. Whether you should go for a model offering universal fit? Or is a system offering direct fit more beneficial? Let us help you answer this question.
- Universal fit
Cold air intakes that offer the facility of universal fitment are compatible with most carbureted engines. Their one-type-fits-all design requires little modification for you to install them under the hood.
However, while you don’t have to modify their design, you do have to purchase additional equipment to get these systems in line with the design of your engine.
- Direct fit
Slightly costly and more difficult to find, cold air intakes that are made for 6.7 Cummins don’t require you to purchase any additional equipment or make any modifications to their design.
All you have to do to install them under the hood is to unlock their package, open your hood and fit them. That’s why their installation time is as brief as 90 minutes.
Q: What type of filter is included with the intake?
A: Most cold air intakes you see on the market consist of two parts. The first one is the long pipe that draws in air from outside. The second is the filter that cleans the incoming air. You might want to pay extra attention to how the filter does its work as it will have an impact on your engine’s performance.
- Dry Filter
Dry filters operate in much the same way as your car’s air or AC filter. They have a synthetic fabric or cotton gauze that keeps the dust particles from passing through and disturbing the engine.
Such an operating mechanism do have its drawbacks. It lowers the operating life of the filter, forcing you to clean it every now and then and replace it altogether once every 15,000 to 30,000 miles.
- Oiled Filter
Such filters rely on a thin layer of oil to capture and trap dust particles from the air passing through them. They are long lasting and last as much as 100,000 miles before needing cleaning.
Most of them are pre-oiled though some do require you to refill the oil every now and then. They are also washable and can therefore be rinsed away with a mixture of water and soap.
Q: What is the material of construction of the intake tube?
A: Cold air intakes’ tubes are generally made of one of two materials: plastic or metal. The former are available in either specialized plastic or composite form. They are the least expensive option and have a subdued style that complements well that of your engine.
Choose a plastic intake tube if:
- You’re looking for the most inexpensive option
- You want an intake whose style complements that of your engine
Metal intake tubes do not offer any significant advantage over their plastic counterparts. The only reason why some people might prefer them over plastic tubing is because of their design. As it helps you style your engine to the maximum.
Choose a plastic intake tube if:
- You are looking to style your engine compartment to the maximum
- You steer well clear of cheap products in daily life
Q: Does the intake tube has any sort of coating?
A: Some of the premium cold air intakes come with a heat-resistant, carbon-black powder coating. It isn’t only there for the looks. The coating resists the build-up of scratches, keeps rust at bay and minimizes the likelihood of corrosion. But it doesn’t stop at that.
It also isolates the built-in air filter from the engine components that are surrounding it. This shields the filter from the heat build-up that is accumulating around it. You don’t need us reminding you the benefits the filter will get from such an arrangement.
Conclusion
Increased horsepower, enhanced uphill performance and better mileage are some of the benefits you could expect from the best cold air intakes for 6.7L Cummins mentioned above. That is not where the good news end.
These models might be expensive but justify their lofty asking prices by increasing your engine’s combustion efficiency and improving its noise. Almost all support bolt-on installation and are therefore a cinch to assemble. What more can you ask for!
