Best Air Filter for 6.7 Cummins
S&B Filters 75-5092D Cold Air Intake Filter
The S&B Filters 75-5092D Cold Air Intake Filter provides the best of both worlds. On the one end, it uses a dry filter gauze to trap dust and dirt particles. This mechanism makes sure that any debris entering the inlet with the incoming air won’t be able to make its way to the engine.
On the other end, this model’s premium silicone construction enables it to allow 49.77% more air to the engine. That allows the engine to boost an efficiency rating of 99.50%. It also enhances your vehicle’s combustion efficiency and results in an increase in its uphill performance.
S&B devoted quite many man-hours to the construction of this model. That is precisely the reason why it offers a direct fit to your 6.7 Cummins engine. You won’t have to undertake any enhance turning or recalibrate your stock for its fitment.
On top of everything else, this cold air intake filter has a custom enclosure that keeps unwanted engine heat out. It also has an MAF (Mass Air Flow) sensor that helps keep the ‘check engine’ light off and is equipped with a secondary outlet that eliminates any restrictions in the route of the incoming air.
Pros
- Premium silicone construction
- Custom enclosure keeps unwanted engine heat out
- Ensures less restrictive airflow
Cons
- Have to drill to use the plastic hole
FRAM Extra Guard Air Filter
Everything about this air filter points to a unit that is exceptionally durable. It relies on a heavyweight screen which not only keeps dirt and dust particles at bay but also ensures greater filter integrity. Similar is the case with its pleat-lock glue bead.
Users can count on the glue bead to provide consistent air flow, minimize the restrictions in the passageway of the air and a better filter performance throughout the life of this model. It is also one of the main reasons why the Extra Guard boasts a 99% efficiency.
You’ll be equally pleased to note the operating life of this model. Most filters you see on the market give way after 2,000 to 5,000 miles on the road. Not this one. Periodic maintenance and cleaning schedule will keep this filter going strong for up to 12,000 miles.
To further sweeten the deal, FRAM has kept this filter’s installation as easy as follows. All you have to do to install it under the hood is to wear protective gear, loosen its wing nut to remove the filter cover, place it in the position of your previous air filter and fasten the wing nut after replacing the cover.
Pros
- Lasts up to 12,000 miles
- Prevents decreased acceleration
- Improves overall performance
Cons
- None
Mopar 53034051AB Air Filter
Most air filters you see in this review are inexpensive. The Mopar 53034051AB Air Filter is an exception. You can gauge it from the fact that this single air filter costs more than the previous two models put together. But it justifies its astronomical asking price with worth-having features.
Start with its warranty period. Prior experience might have told you that air filter manufacturers generally don’t provide any guarantee on their products. Mopar, however, raises the bar by warrantying its air filter for 2 years or unlimited miles during this period.
Then comes its ability to replace your stock parts. It is a genuine replacement part for your Dodge, Jeep, and Chrysler. The size and dimensions of this air filter are all according to the requirements of these three vehicles. That means you won’t have to make any modifications to your engine to install it.

Your engine will receive 51.68% more air after the installation of this filter as compared to what it currently gets from the stock filter.
Hence the reason why it empowers your engine to boast an efficiency rating of 99.5%. The testing of this intake filter against internationally accepted ISO 5011 standard serves as proof that this model would outlast its competitors. You won’t have to buy its replacement anytime soon.
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.
Similar to the S&B dry air filter we discussed above, this one too has an MAF (Mass Air Flow) sensor to keep the ‘check engine’ light off. The similarities don’t stop there.

Start with the best. It is equipped with state-of-the-art filtration media that beats ordinary air filters by providing up to 50% more air flow. The filter media does that by preventing any clogging that could reduce its airflow and, by extension, the performance of your engine.
Its ease of installation was another feature of this model that impressed us. K&N delivers it to your doorstep pre-oiled, so you just have to take out your existing air filter and drop this one into the factory air box. That is why we call it one of the easiest upgrades for your vehicle.

Wix Heavy Duty Air Filter
One of the defining features of this heavy-duty air filter is its full-metal base plate. It features a double seal to provide superior strength. Also, there is a silicone anti-drain back valve that remains flexible in extreme weather conditions and improves oil flow.
Equally useful is this model up-front bypass valve. It gets one up over top-mounted valves by keeping the oil from washing past dirty media. The filter uses a glass-enhanced media for greater efficiency and captures dirt particles ranging between 10 and 12 microns in size.
Then comes the linear path through the air filter that ensures low restriction to airflow. Wix has used a specially formulated adhesive to make the pocket pleat for its filter media and has also equipped this air filter with a soft-sealing urethane gasket.
On top of everything else, this radial air filter is protected from the inside by a mesh screen. The screen ensures element strength and will protect the filter media in case of any backfire. All in all, this model has all the hallmarks of a heavy-duty air filter.

Best 6.7 Cummins Air Filter – Must-have features
Here are some of the features and specs which are a must-have for the 6.7 Cummins air filters:
- Long lifespan: One of the stand-out features of the best-selling air filters is that they offer up to 100,000 miles of road use. That means that you can count on them to remain useful for at least the next three years to come.
- Extended maintenance intervals: Almost all the class-leading air filters have one thing in common. They don’t force you to take them out and rinse away the embedded dirt after every few thousand miles.
- Quiet performance: Do you like hearing the workings of everything that is under the hood? Neither do we. Hence the reason we recommend that you go for a model that doesn’t drive up your air intake’s noise level.
FAQs
Q: What is the type of filter?
All air filters available on the market come in one of two types. They are either dry and use a cotton gauze to block dirt and debris. Or they are pre-oiled and use a thin film of oil to trap the incoming dirt particles and keep them from harming the engine’s performance.
Dry Filter
Dry air filters have the same operating mechanism as your car’s AC filter. They have a synthetic or cotton gauze, one which protects the engine by keeping the dust particles from getting through the intake.
Not that they aren’t without any faults. Dry filters have a smaller shelf life than wet filters and they don’t have class-leading maintenance intervals either. That is to say you’d have to clean and altogether replace them frequently.
Oiled Filter
We have already stated that these filters count on a thin film of oil to trap the incoming dirt particles. The build-up of dirt on the oil isn’t that huge, which is why these filters can get by 12,000 to 15,000 miles before needing cleaning.
But you don’t have to worry about maintaining them. Most oiled filters you see in this review are washable. You just have to rinse dirt particles off their surface with soapy water and they’d be good to use again.
Q: What do you want the air filter to do?
Depending on your answer to this question, you’d have two options. Those of you who don’t want a massive increase in performance from your vehicle will do well with OEM air filters. Others who are looking to improve the horsepower of their truck might want to pick a short ram intake system or cold air intake system. Here’s why we are saying that:
OEM Air Filters
These filters do what is written on their package. They are tailor-made replacement for your factory parts and have the ability to effectively filter out debris, dirt, and other contaminants.
That isn’t to say that there is no virtually no difference between these air filters and your truck’s factory ones. If anything, these models provide a better airflow than standard air filters and offer higher filtration capacity too.
High-Performance Air Filters
Available in two types – cold air intake system and short ram air intake system – the high-performance air filters increase the performance of your engine, enhance its uphill performance and boost its horsepower.
Most of them have deeper pleats in their creases and a larger surface area than the standard air filters. This enables them to block a large number of dirt particles while allowing for maximum airflow at the same time.
Q: Does the filter offer a universal or custom fit?
Once you have answered all the questions asked above, you’d have to decide between a filter that offers universal fitment and others that provide a custom fit. As has been the theme throughout this article, we’re going to help you answer this question.
Universal Fit
Universal air filters do what you expect from them. They don’t require you to perform any modifications to install them under the hood. You can also count on them to be compatible with your 6.7L Cummins.
The majority of these models come with clamps that let you attach them onto your existing air intake system. They won’t weigh heavily on your pocket as well as universal air filters are inexpensive too.
Custom-Fit
Similar to universal air filters, those that are made specifically for your model and make can also deliver notable improvements in mileage, horsepower and torque.
Unlike them, these models ensure hassle-free installation. Their unique design also makes these filters ideal for stopping the finer grit that usually gets through universal air filters.

That is where this article comes into play to change your perception. Its pricey models have the features as well as the durability to justify their asking price. You can, therefore, rest assured that you won’t be ripped off after spending a few extra dollars on their purchase.
