The 6.7L Power Stroke is a strong-flowing diesel from the factory, but the stock airbox and restrictive intake tube leave airflow on the table that a properly engineered cold air intake can recover. A good intake feeds the turbo cooler, denser air, sharpens throttle response, and on many trucks adds a deeper induction note under load. The catch is that this engine is sensitive to one thing above all: filtration. Fine dust that slips past a poorly sealed filter can score cylinder walls and shorten the life of an expensive long block, so on a diesel the filter and the seal matter just as much as the flow number.
We focused on intakes that actually fit the 2011 through 2025 Super Duty trucks, sealed properly to the factory airbox or to a dedicated housing, and used media that protects this engine instead of just chasing a horsepower headline. Below are seven real options worth your money, ranked best first, with honest notes on where each one shines and where it falls short.

1. S&B Filters 75-5100 Cold Air Intake (Cotton Cleanable): Best Overall
S&B has built its reputation on diesel intakes, and the 75-5100 for the 6.7 Power Stroke is the one we keep coming back to. The fully enclosed housing is the headline feature. Instead of leaving a cone exposed to radiant heat off the turbo and exhaust, S&B boxes the filter in and seals it to the hood line and fender, so the air the turbo draws stays closer to ambient temperature. That sealed design also matters for filtration, because there is one clear path for air and it goes through the media, not around a leaky gasket.
The honest weakness is the oiled cotton filter that ships on the standard kit. Over-oil it during a re-clean and you risk leaving residue on the MAF sensor, which can throw codes and skew fueling. The fix is simple, buy the dry filter version or oil sparingly, but new owners do trip over it. If you are willing to follow the cleaning instructions, this is the intake we would put on our own truck.
- Fully sealed roto-molded housing isolates the filter from hot engine bay air
- Large conical filter with a much greater media area than the stock element
- Offered in oiled cotton or a dry-extendable filter version for your preference
Pros: Outstanding fitment and a genuinely airtight seal that protects the engine; Strong, independently published airflow gains over the factory box; Filter is washable and reusable, so it pays for itself over years of ownership
Cons: Oiled cotton version requires careful re-oiling to avoid MAF sensor issues; Filter cleaning and full dry time mean you cannot reinstall it the same hour
2. aFe Power Momentum HD Cold Air Intake (Pro 10R): Best Filtration
aFe’s Momentum HD is the intake we recommend when filtration is the top priority, and on a hard-working diesel it usually should be. The Pro DRY S synthetic media is the standout, delivering very high dust-holding capacity without any oil at all, which removes the MAF-contamination worry entirely. If you tow heavy in dusty conditions, the dry filter and the sealed one-piece housing are a reassuring combination that keeps fine grit out of the turbo and cylinders.
Where it stumbles slightly is installation. The housing is a tight, precise fit, and getting the seals seated cleanly the first time takes more fiddling than some competitors. It is not difficult, but plan for a deliberate install rather than a ten-minute swap. Once it is in and sealed correctly, the Momentum HD breathes freely and protects the engine about as well as anything on this list.
- Heavy-duty one-piece housing with a tight seal to the factory cold-air inlet
- Choice of Pro 10R oiled media or Pro DRY S synthetic for low-maintenance use
- Available with a clear viewing lid so you can check filter condition at a glance
Pros: Excellent dust holding and filtration efficiency for a diesel application; Rotomolded housing is rugged and seals well against under-hood heat; Dry media option makes maintenance simple with no oiling required
Cons: Pro 10R oiled filter needs the same careful re-oiling discipline as any cotton media; Housing is a snug fit that rewards patience during installation
3. Banks Power Ram-Air Cold Air Intake System: Best Engineered
Banks approaches intakes like an engineering problem rather than a styling exercise, and the Ram-Air system shows it. The molded tube and velocity stack are computer-flowed to smooth the path into the turbo compressor, and the enclosed airbox is sized generously so the filter is rarely the bottleneck. Banks publishes its own airflow and dyno numbers, and on the 6.7 Power Stroke the Ram-Air consistently posts some of the best measured flow we have seen, which translates to cooler, denser air during long pulls.
The trade-off is twofold. It sits toward the upper end of the market in terms of what you invest, and the large airbox physically takes up room, so on trucks with crowded engine bays you will want to dry-fit before committing. Neither is a dealbreaker for a serious owner, but if you want the smallest, simplest install on this list, Banks is not it. For outright performance backed by real data, it is hard to beat.
- Oversized enclosed airbox engineered for maximum flow at the turbo inlet
- Smooth molded tube and velocity stack reduce turbulence into the compressor
- Backed by real dyno and airflow data published by Banks rather than vague claims
Pros: Among the highest measured airflow figures for this engine; Thoughtful, data-driven engineering and excellent build quality; Sealed airbox keeps intake temperatures low under sustained load
Cons: Premium feel and engineering put it at the higher end of the value spectrum; Large airbox can crowd the engine bay around other accessories
4. K&N 71-2581 Blackhawk Induction Cold Air Intake: Best Drop-In Brand Trust
K&N is the name most people think of first when they hear cold air intake, and the Blackhawk Induction kit brings that pedigree to the 6.7 Power Stroke. The oiled cotton-gauze filter flows well and gives the truck a more assertive induction note, and the heat shield does a reasonable job of keeping the filter away from the hottest air in the bay. The Million Mile warranty is a genuine confidence builder, because it tells you K&N expects this hardware to outlast most owners.
The weakness is the same one that follows any oiled cotton filter, and on a diesel it deserves respect. Re-oil it heavily and you can leave film on the MAF sensor and trigger fueling complaints. The heat shield, while effective, is also not as completely sealed as the boxed designs from S&B or aFe, so peak intake-air-temperature control is a small step behind the very best. For buyers who trust the K&N name and will follow the cleaning routine, it remains a solid pick.
- K&N's signature oiled cotton-gauze media with a large conical filter
- Enclosed heat shield helps separate the filter from hot engine bay air
- Covered by K&N's Million Mile Limited Warranty for long-term confidence
Pros: Trusted brand with decades of cotton-gauze filter experience; Strong throttle response and a noticeable induction sound under load; Washable filter and a long warranty back the purchase
Cons: Oiled media demands careful re-oiling to avoid MAF sensor fouling; Heat shield is less fully enclosed than the top sealed-box kits
5. Mishimoto Performance Cold Air Intake: Best Build Quality
Mishimoto built its name on cooling and intake parts that look as good as they perform, and its 6.7 Power Stroke intake carries that reputation. The sealed airbox keeps the filter shielded from hot under-hood air, and the overall build quality is a clear step above the budget end of the market. The lifetime warranty is a meaningful backstop, and the option to run a dry filter makes ongoing maintenance painless for owners who do not want to oil and clean media.
The honest limitation is that the airflow gains, while real, are merit-class rather than the very top of the chart. If you are chasing the absolute highest measured flow, Banks and S&B edge it out. You should also double-check exact-year fitment before ordering, because coverage and stock can shift between model years. As a beautifully made, well-sealed daily-driver intake, though, it earns its place.
- Sealed airbox design keeps the filter isolated from radiant engine heat
- Offered with oiled or dry filter media to match your maintenance style
- Backed by Mishimoto's lifetime warranty on the intake hardware
Pros: Premium fit and finish that looks and feels well made under the hood; Sealed box delivers good intake temperatures and clean filtration; Lifetime warranty shows confidence in long-term durability
Cons: Airflow gains are solid rather than class-leading versus the top performers; Availability and fitment can vary by exact model year, so verify before buying
6. Volant PowerCore Closed Box Cold Air Intake: Best Dry Filter Box
Volant’s closed-box approach pairs a fully enclosed housing with PowerCore dry media, and that combination is exactly what a lot of diesel owners actually want. There is no oil to manage, the efficiency is high, and the service interval is long, so you can install it and largely forget about it for thousands of miles. The closed box does its job keeping intake temperatures down, which is the whole point of a cold air intake on a turbo diesel that already generates plenty of underhood heat.
The trade-off is character. PowerCore media is built for efficiency and dust holding rather than the last few CFM, so peak airflow is slightly behind the most aggressive oiled-cotton setups, and the induction sound is restrained. If you want the loudest, most free-flowing intake, look elsewhere. If you want a clean, sealed, maintenance-light box that protects your engine, the Volant is an easy recommendation.
- Fully closed-box housing seals the filter from hot engine bay air
- PowerCore dry media offers high efficiency with no oiling required
- Long recommended service interval reduces how often you touch the filter
Pros: Genuinely low-maintenance dry filter with no MAF oiling worries; Closed box keeps intake-air temperatures down effectively; Rugged housing handles the under-hood environment well
Cons: Dry media flows a touch less freely than the most aggressive oiled filters; Style and sound are subtle rather than dramatic
7. Spectre Performance Air Intake Kit: Best Value Entry
Spectre, part of the same group as K&N, offers the most approachable way onto this list. The kit centers on a large conical oiled filter and a heat shield, and the installation is genuinely simple, making it a good first modification for an owner who wants more flow and a bit more sound without a complicated job. The washable filter keeps long-term maintenance straightforward, and the basic engineering is sound.
The clear weakness is that an open-element heat-shield design cannot match the temperature control of a fully enclosed box. With more of the engine bay’s hot air able to reach the filter, peak intake temperatures run higher than the sealed kits above it, which matters most during long, loaded pulls. As an honest, easy entry-level intake that breathes better than stock, it does what it promises, just do not expect it to outperform the closed-box leaders.
- Large conical oiled filter for improved flow over the stock element
- Heat shield helps block some radiant heat from the filter
- Straightforward bolt-on kit with common hand tools
Pros: Accessible entry point into a performance intake without overcomplication; Easy, beginner-friendly installation in under an hour; Washable filter keeps long-term upkeep simple
Cons: Open-element design is less sealed than a full closed-box intake; Heat shield does not control intake temperatures as well as enclosed kits
Frequently Asked Questions
Will a cold air intake add horsepower to my 6.7 Power Stroke?
On its own, a cold air intake usually adds a modest, hard-to-feel amount of peak horsepower, but that is not really the point on a diesel. The bigger benefits are cooler intake-air temperatures, better airflow to the turbo, sharper throttle response, and headroom for future tuning. If you later add a tuner or larger turbo, a free-flowing intake stops the factory airbox from becoming the bottleneck, which is where the real gains show up. Think of the intake as the foundation rather than the finished house.
Are oiled filters or dry filters better for a diesel like the 6.7?
Both work, and the right answer depends on you. Oiled cotton filters generally flow a little more freely and give a stronger induction sound, but they require careful re-oiling, and over-oiling can leave residue on the MAF sensor and cause fueling complaints. Dry synthetic media flows slightly less but offers very high dust-holding efficiency with zero oiling and no MAF worry, which makes it the lower-maintenance, lower-risk choice for many owners who tow in dusty conditions. If you want confidence, go dry. If you want maximum flow and will follow cleaning instructions, oiled is fine.
Will installing an aftermarket intake void my Ford warranty?
Under the Magnuson-Moss Warranty Act, a manufacturer cannot void your entire warranty simply because you installed an aftermarket part. However, if a dealer can show that the intake directly caused a specific failure, they can deny that particular claim. The most common real-world risk on a diesel is dust damage from a poorly sealed or over-oiled filter, which is exactly why fitment and filtration matter so much. Keep your receipts, install the kit correctly, and choose a well-sealed intake to keep your coverage intact.
Does a cold air intake on the 6.7 Power Stroke make it louder?
Yes, most owners notice a deeper, more pronounced induction sound under acceleration and load, especially with open-element or oiled-cotton kits. Fully enclosed closed-box designs with dry media tend to be the most subtle, while open conical filters with a heat shield are usually the most vocal. The turbo spool and air rush become more audible, which many drivers enjoy. If a quiet cabin is your priority, lean toward a sealed box with dry media rather than an open-element intake.
How often do I need to clean the filter on a 6.7 Power Stroke intake?
It depends on the filter type and how dusty your driving is. Dry synthetic filters often go many thousands of miles, sometimes 20,000 or more, between cleanings, and some closed-box dry kits are rated for very long service intervals. Oiled cotton filters typically want attention more frequently, especially if you spend time on dirt roads or job sites. The simplest habit is to inspect the filter at every other oil change. If it looks loaded with dirt, clean it according to the maker’s instructions and let oiled media dry fully before re-oiling and reinstalling.
Our Verdict
For most 6.7 Power Stroke owners, the S&B Filters 75-5100 is our top pick because it combines a fully sealed housing, excellent fitment, strong proven airflow, and a washable filter that pays for itself over years of ownership. If filtration and zero-maintenance confidence are your priority, especially for heavy towing in dusty conditions, the aFe Power Momentum HD with Pro DRY S media is the runner up and an outstanding choice. Either one will protect your engine while letting it breathe far better than the factory airbox, which is exactly what a good diesel intake should do.
