The 6.7L Powerstroke is a strong diesel from the factory, but the stock airbox and restrictive intake tube leave power and throttle response on the table, especially when you are towing heavy or running warm climates. A good cold air intake opens up airflow, pulls cooler air from outside the engine bay, and on many trucks helps keep exhaust gas temperatures in check under load. The wrong one, though, just sucks in hot under hood air and adds noise without real gains.
We focused on intakes that actually fit the 2011 to 2025 6.7 Powerstroke generations, looking at filter quality, how well the box seals against heat, airflow numbers, and how each one behaves when you hook up a trailer. Below are seven real, proven options ranked best first, with honest pros, cons, and the weak spots most reviews skip.

1. S&B Filters Cold Air Intake Kit (75-5101) for 6.7 Powerstroke: Best Overall
S&B has become the default answer for 6.7 Powerstroke owners who want a real cold air intake rather than just a louder one. The kit centers on a fully sealed roto-molded airbox that closes against the hood, so the oversized filter only ever sees cool air drawn from outside the engine bay. That sealing is the part that actually matters on a diesel, and S&B does it better than most. The huge filter element flows hard, keeps restriction low even at high RPM, and the generous surface area means you go a long time between cleanings.
You can order it with either the cleanable oiled cotton filter or a dry disposable element, which is a nice touch since many diesel owners worry about oil getting onto the MAF sensor. The honest weakness is the oiled version: if you re-oil too heavily after cleaning you can foul the sensor or attract more dust, so you have to follow the instructions carefully. It also asks a bit more of your wallet than basic kits, but the build quality, fitment, and sealing justify it for most buyers who tow.
- Fully enclosed roto-molded airbox that seals to the hood for true cold air
- Choice of oiled cotton cleanable filter or dry disposable element
- Massive filter surface area for high airflow and long service intervals
Pros: Sealed box genuinely isolates the filter from hot engine bay air; Strong airflow gains help throttle response and can ease EGTs when towing; Choice of oiled or dry filter to suit your maintenance preference
Cons: Oiled filter version needs careful re-oiling to avoid over saturating; Premium build sits at the higher end of the range for value
2. aFe Power Momentum HD Cold Air Intake for 6.7 Powerstroke: Best for Towing
The aFe Momentum HD is the intake we reach for when towing is the main mission. The sealed one piece housing with its clear inspection window means hot air stays out and you can eyeball the filter without pulling anything apart, which is genuinely useful when you are checking things at a fuel stop mid trip. The large bore rotomolded tube smooths airflow into the turbo, and under heavy load the truck feels like it breathes easier, with exhaust temps that climb a little more slowly on long grades.
aFe lets you pick between the Pro 10R oiled media for maximum flow or the Pro DRY S synthetic media that needs no oil, so you can match it to how you maintain trucks. The catch is the same as any premium oiled filter: the Pro 10R version rewards careful cleaning and light re-oiling, and over-oiling can upset the MAF reading. A few owners also report needing patience to seat the box perfectly on certain early trucks, but once it is in, fit and performance are excellent.
- One piece sealed Momentum housing with a clear view window
- Choice of Pro 10R oiled or Pro DRY S media
- Large diameter rotomolded intake tube for smooth high volume flow
Pros: Sealed housing and large tube deliver excellent airflow under load; View window lets you check filter condition without removing the box; Heavy duty media options hold up well in dusty towing conditions
Cons: Oiled Pro 10R requires the usual careful re-oiling discipline; Slightly tighter fit checks on some early build trucks
3. K&N 63 Series AirCharger Cold Air Intake for 6.7 Powerstroke: Best Lifetime Filter
K&N built its name on the washable cotton gauze filter, and the 63 Series AirCharger brings that to the 6.7 Powerstroke with a molded heat shield and a reusable element that is designed to last the lifetime of the vehicle. For owners who hate buying replacement filters, this is the appeal: clean it, re-oil it, reinstall it, repeat for years. The limited lifetime warranty backs that up, and the brand is so widely stocked that parts and service kits are never hard to find. Throttle response and intake sound both sharpen up noticeably.
The honest tradeoff is sealing. The 63 Series uses an open heat shield rather than a fully enclosed box, so it does not isolate the filter from hot engine bay air quite as well as the sealed S&B or aFe kits, which matters most on hot days and hard pulls. As with all oiled cotton media, you have to clean and re-oil it correctly or risk fouling the MAF sensor. If you value a do it once filter and brand support over the last bit of cold air sealing, it is a great pick.
- Washable and reusable cotton gauze filter built to last the life of the truck
- Molded heat shield helps keep the filter away from engine heat
- Backed by K&N limited lifetime warranty coverage
Pros: Reusable filter means no recurring element purchases; Strong brand support and easy to find replacement parts; Noticeable improvement in intake sound and throttle feel
Cons: Open heat shield design does not seal as completely as a fully boxed kit; Oiled cotton media must be cleaned and re-oiled correctly
4. Banks Power Ram-Air Cold Air Intake for 6.7 Powerstroke: Best Engineered
Banks approaches the intake like an engineering problem, and the Ram-Air kit for the 6.7 Powerstroke reflects that. The fully enclosed housing keeps hot air out, while the smooth, large radius tubing is shaped to reduce turbulence on the way to the turbo. Banks publishes airflow testing rather than vague horsepower claims, which is refreshing, and in use the truck feels crisp off idle with steady breathing at the top of the rev range. Build quality is excellent and everything lines up the way a well thought out kit should.
You can spec it with oiled cotton or dry media depending on your maintenance habits. The main drawbacks are value and clarity: it sits among the more expensive options, and some first time buyers wish the filter media choice was explained more plainly before purchase. None of that changes the fact that this is a very carefully designed intakes available for the platform, and a smart pick for owners who trust data over marketing.
- Fully enclosed Ram-Air housing engineered and dyno validated
- Smooth large radius tubing to reduce turbulence into the turbo
- Available with oiled cotton or dry synthetic filter media
Pros: Engineering driven design with published airflow testing; Enclosed housing seals well against under hood heat; Strong, durable construction that fits cleanly
Cons: One of the pricier kits relative to simpler options; Some buyers want clearer guidance on oiled versus dry choice
5. Spelab Cold Air Intake Kit for 6.7 Powerstroke: Best Value
Spelab has carved out a spot with the value crowd, and its 6.7 Powerstroke intake delivers most of what you want from a cold air kit without the premium outlay. The enclosed box style heat shield does a respectable job of keeping the high flow oiled cotton filter away from the hottest engine bay air, and installation is a straightforward bolt on using factory points with the included hardware. For owners who want more airflow and a deeper intake note without spending big, it punches above its weight.
Where it gives ground is in materials and finish. The plastics, clamps, and overall fit and feel are a clear step below S&B, aFe, or Banks, and a few units need a little fettling to seat perfectly. As with any oiled cotton filter, you must clean and re-oil it properly to avoid MAF issues. If you understand it is a value kit rather than a flagship, it is one of the smarter affordable choices for the platform.
- Enclosed box style heat shield for a more sealed airflow path
- High flow oiled cotton filter included in the kit
- Direct bolt on installation using factory mounting points
Pros: Strong airflow improvement for an accessible price point; Enclosed box seals better than a bare open filter; Simple bolt on install with included hardware
Cons: Materials and finish are a step below the premium brands; Oiled filter needs correct cleaning to protect the MAF
6. Volant Closed Box Cold Air Intake for 6.7 Powerstroke: Best Sealed Box
Volant leans hard into the sealed box philosophy, and that is exactly why it earns a spot here. The fully enclosed housing isolates the filter from engine heat about as well as anything on the list, and the tough cross link molded construction shrugs off the kind of abuse a work or off road 6.7 sees. You can run it with the maintenance free PowerCore filter, which lasts a long time without any oiling, or a traditional oiled cotton element if you prefer to clean and reuse.
The compromise is at the top end of the airflow curve. Volant prioritizes sealing and durability over chasing the absolute highest flow numbers, so peak airflow trails the biggest S&B and aFe kits a touch. The PowerCore filters are also less commonly stocked than standard cotton elements, so plan replacements ahead. For owners who care more about consistent cold air and a bombproof box than squeezing out the last CFM, it is a strong, sensible choice.
- Fully enclosed sealed box keeps the filter isolated from heat
- Available with maintenance free PowerCore or oiled cotton filter
- Durable cross link molded housing built for rough use
Pros: Closed box design seals very well against under hood heat; PowerCore option gives long life with no oiling required; Tough housing handles off road and work truck abuse
Cons: Peak airflow trails the highest flowing premium kits; PowerCore replacement filters are less commonly stocked
7. Airaid MXP Series Cold Air Intake for 6.7 Powerstroke: Best for Daily Drivers
The Airaid MXP Series is the easygoing daily driver pick for the 6.7 Powerstroke. Its sealed airbox keeps the filter away from hot engine bay air, and the dyno developed intake tube delivers steady, predictable improvements in throttle response and airflow without drama. The standout option is the SynthaMax dry filter, which needs no oil at all, so you sidestep the whole MAF fouling concern that hangs over oiled cotton media. For an owner who wants a clean, fit and forget upgrade, that is a real plus.
It is a balanced kit rather than a maximum effort one. If your truck spends most days hauling heavy at the redline, the biggest sealed S&B and aFe boxes will out flow it and the Airaid will feel a touch tamer in both sound and peak numbers. The oiled SynthaFlow version, if you choose it, still demands proper cleaning and re-oiling. But for mixed daily and light towing duty, the MXP is a tidy, well rounded intake that just works.
- Sealed intake box that keeps hot air away from the filter
- Choice of SynthaMax dry filter or SynthaFlow oiled media
- Dyno developed intake tube for steady everyday gains
Pros: Dry SynthaMax option means no re-oiling and no MAF worry; Balanced design that suits daily driving and light towing; Clean fit and finish with solid included hardware
Cons: Not the loudest or highest flowing option for heavy haulers; Oiled SynthaFlow version still needs careful maintenance
Frequently Asked Questions
Will a cold air intake add horsepower to my 6.7 Powerstroke?
On its own, a cold air intake on the 6.7 Powerstroke usually adds modest gains, often improving throttle response and airflow more than it bumps peak horsepower. Diesels respond mostly to fuel and tuning, so the intake is best thought of as a supporting mod that lets the engine breathe freely and pulls in cooler air. The bigger gains show up when an intake is paired with a tune and a less restrictive exhaust. By itself you will mostly notice sharper response, a deeper intake note, and better high RPM airflow rather than a huge dyno jump.
Does a cold air intake help lower EGTs when towing?
It can help, but it is not a cure on its own. A properly sealed cold air intake feeds the turbo cooler, denser air from outside the engine bay, and cooler intake air can translate to slightly lower exhaust gas temperatures under load compared to a restrictive or heat soaked stock setup. The keyword is sealed: an open filter that sucks in hot under hood air can actually work against you on a long, hot grade. Pair a sealed intake with sensible tuning and an EGT gauge if towing heavy is your main concern.
Should I choose an oiled filter or a dry filter?
It comes down to maintenance preference and added security. Oiled cotton filters like K&N media and aFe Pro 10R generally flow a little more and are washable and reusable, but they must be cleaned and re-oiled correctly because over-oiling can foul the MAF sensor. Dry synthetic filters such as aFe Pro DRY S, Airaid SynthaMax, and Volant PowerCore need no oil, remove the MAF worry, and are very low fuss, trading a small amount of peak flow. Many 6.7 owners pick dry media specifically to avoid any chance of MAF contamination.
Will a cold air intake void my Ford warranty?
Under the Magnuson Moss Warranty Act, a manufacturer generally cannot void your entire warranty simply because you installed an aftermarket part. However, if a dealer can show that a specific intake directly caused a failure, that particular repair could be denied. To protect yourself, keep your receipts, follow the install instructions exactly, and maintain the filter properly, especially if you run oiled media near the MAF sensor. A correctly installed, reputable intake from the brands listed here is very unlikely to cause warranty trouble for most owners.
Is a cold air intake hard to install on a 6.7 Powerstroke?
For most of these kits it is a straightforward bolt on job that a reasonably handy owner can finish in well under an hour with basic hand tools. The intakes reuse factory mounting points and include the needed hardware, clamps, and instructions. The main things to get right are seating the box so it seals against the hood properly, tightening the clamps so there are no air leaks ahead of the MAF, and routing everything clear of hot or moving parts. Take your time on the sealing and clamp steps and the rest is simple.
Our Verdict
For most 6.7 Powerstroke owners the S&B Filters Cold Air Intake Kit is the top pick, thanks to its genuinely sealed roto-molded box, huge high flow filter, and the choice of oiled or dry media that suits anyone from daily drivers to heavy haulers. Our runner up is the aFe Power Momentum HD, which matches that sealed, big airflow approach and adds a handy inspection window that makes it especially appealing for owners who tow long distances and want to keep an eye on filter condition. Either one is a confident, lasting upgrade for the platform.
