The 6.7L Powerstroke diesel gives the Ford Super Duty the torque and capability needed for serious towing, hauling, and demanding everyday use.

But before the turbocharger can create boost, it needs air.

Every restriction between the outside atmosphere and the turbo inlet makes the intake system work harder to supply the airflow demanded by the engine.

That is where the S&B Cold Air Intake System for the 2020–2027 Ford Super Duty 6.7L Powerstroke comes in.

Available from Extreme Power House, S&B part number 75-5140 replaces the restrictive factory intake path with an oversized high-efficiency filter, streamlined intake tube, fully enclosed airbox, and configurable secondary air inlet.

S&B designed the system to provide up to 39.05% more airflow than the factory intake while maintaining 99.42% filtration efficiency.

That combination is particularly important on a diesel truck.

Increasing airflow matters.

But protecting an expensive turbocharged diesel engine from dirt and contaminants matters just as much.

Why Intake Airflow Matters on the 6.7L Powerstroke

A turbocharged diesel engine consumes a tremendous amount of air under load.

When a Super Duty is accelerating, towing a trailer, climbing a grade, or operating with performance tuning, airflow demand can increase significantly.

The turbocharger has to pull that air through the complete intake tract before compressing it and sending it toward the engine.

Any unnecessary bends, narrow sections, or restrictions upstream of the turbo can make that process less efficient.

The S&B intake is designed to reduce those restrictions by providing a cleaner path from the air filter through the airbox and toward the turbo inlet.

The result is a system capable of moving substantially more air than the factory configuration.

Up to 39.05% More Airflow Than Stock

S&B reports that the 75-5140 intake provides up to 39.05% more airflow compared with the factory system.

That is an airflow measurement—not a horsepower claim.

The benefit comes from reducing the amount of restriction the incoming air encounters before reaching the engine.

For a stock truck, that gives the intake system more airflow capacity.

For a tuned or otherwise modified Super Duty, additional intake capacity can become even more useful as the engine demands greater airflow.

The intake is therefore relevant to both factory-calibrated trucks and vehicles running enhanced tuning.

99.42% Filtration Efficiency

High airflow only matters if engine protection is maintained.

S&B specifies 99.42% filtration efficiency for this system.

That balance is one of the most important aspects of a diesel cold-air intake.

Super Duty trucks may operate in environments that passenger cars rarely encounter:

Construction sites.

Dusty roads.

Farms.

Gravel routes.

Work areas.

Long highway trips.

Towing environments.

A performance intake needs to increase airflow without sacrificing the filter's primary job of keeping contaminants out of the engine.

S&B's oversized filter is designed around both objectives.

Oversized Air Filter

The system uses a substantially sized high-efficiency air filter to increase the available filtration area.

A larger filter gives incoming air more surface through which to pass.

Instead of forcing the full airflow requirement through a smaller filtration area, the oversized design distributes airflow across more filter media.

That contributes to the system's ability to reduce intake restriction while maintaining strong filtration efficiency.

For a large-displacement turbo diesel, that additional filter capacity is particularly appropriate.

Fully Enclosed Airbox

Many aftermarket intakes use an exposed filter sitting directly inside the engine compartment.

S&B takes a different approach.

The Super Duty intake uses a fully enclosed airbox.

The enclosure helps shield the filter from dirt and debris while also reducing direct exposure to heat from the engine compartment.

For a working truck, that protection has practical value.

The filter remains contained inside a purpose-built housing rather than sitting completely exposed under the hood.

Designed to Use Cooler Outside Air

A cold-air intake works best when it can take advantage of air entering from outside the engine compartment.

The S&B system retains a front-facing airflow route through the factory grille area and front scoop.

This provides a direct path for incoming air into the enclosed filter housing.

S&B also adds a second configurable air inlet, giving owners control over how much additional air is allowed into the box.

Two Airflow Configurations

One of the most interesting features of the 75-5140 is its removable silicone airbox plug.

The plug allows the owner to operate the airbox in two different configurations.

This gives the system additional flexibility rather than locking every truck into the same inlet arrangement.

Configuration One: Secondary Air Inlet Open

Remove the silicone plug and the secondary side air inlet remains open.

In this configuration, additional incoming air can reach the filter through the passenger-side fender area.

That gives the airbox another source of airflow in addition to the front-facing inlet.

For owners prioritizing maximum available intake airflow, this configuration may be appealing.

Configuration Two: Secondary Air Inlet Closed

Install the supplied silicone plug and the secondary side inlet becomes sealed.

With that opening closed, the system relies primarily on the front-facing grille inlet and front scoop to supply air to the enclosed airbox.

This gives owners the ability to choose the configuration that best suits their preferences and operating conditions.

High-Flow Intake Tube

The filter is only one part of the system.

Air still needs to travel from the airbox to the turbocharger.

S&B designed a high-flow intake tube with minimal bends and obstructions to reduce restriction through that portion of the intake tract.

Every unnecessary change in direction can affect airflow.

The S&B tube is therefore designed to create a more streamlined route between the filter housing and turbo inlet.

That helps the system take advantage of the additional airflow capacity provided by the larger filter.

Less Restriction Before the Turbo

Reducing pre-turbo restriction can be particularly useful on a turbocharged diesel.

The turbocharger draws air through the intake before compressing it.

A more restrictive intake creates a larger pressure drop upstream.

S&B's approach is to provide the turbocharger with a freer-flowing path using the oversized filter and streamlined tubing.

That does not change how the turbo itself operates, but it improves the air path feeding it.

More Noticeable Turbo and Intake Sound

The factory Super Duty intake is designed with noise control in mind.

That keeps the truck relatively quiet, but it also suppresses much of the sound generated by incoming air and the turbocharger.

The S&B system provides a more aggressive intake character.

With the oversized filter and less restrictive intake path, drivers can hear more of the airflow and turbo sound during acceleration.

For diesel enthusiasts, that added sound can make the truck feel more engaging without changing the exhaust system.

Sound That Changes With Engine Load

The added intake sound is not necessarily constant.

During light cruising, airflow demand remains relatively low.

As throttle input and turbo demand increase, the intake becomes more noticeable.

That means much of the additional character appears when the engine is working harder—which is exactly when many enthusiasts want to hear it.

Engineered Around the MAF Sensor

Modern diesel engines rely heavily on sensor data to manage fueling and engine operation.

One of the most important components in the intake tract is the mass airflow sensor, or MAF sensor.

If the sensor area is poorly designed or develops an air leak, the ECU may receive incorrect information about the amount of air entering the engine.

S&B addresses this with an injection-molded MAF sensor plate and dedicated foam gasket.

OE-Style MAF Sensor Seal

The foam MAF gasket is designed to provide an OE-style seal around the mass airflow sensor.

This may seem like a minor installation detail, but it is essential to proper intake operation.

Air should travel through the intended intake path and be measured correctly.

A proper sensor seal helps prevent unwanted air leakage around the MAF housing.

Designed to Support Proper Engine Operation

S&B specifically engineers the system to support correct engine operation with either the factory calibration or enhanced tuning.

That makes the intake suitable for owners who intend to keep the truck otherwise stock as well as those who may continue modifying the 6.7L Powerstroke.

As with any performance modification, tuning requirements for other installed components should always be evaluated separately.

A Natural Upgrade for Towing Builds

Many Super Duty owners are not chasing a dedicated race setup.

Their trucks tow.

Heavy equipment.

Campers.

Car trailers.

Boats.

Work trailers.

During those conditions, the engine may operate under sustained load for extended periods.

That increases airflow demand compared with light unloaded cruising.

A freer-flowing intake is therefore a logical supporting modification for a truck regularly used for demanding towing.

Useful for Tuned 6.7L Powerstroke Trucks

The intake also makes sense as part of a broader performance build.

As tuning increases engine output, airflow requirements can increase with it.

An intake with greater airflow capacity can help ensure the air path is not unnecessarily restrictive as the rest of the truck changes.

Possible supporting upgrades on a modified Super Duty may include:

• Engine calibration
• Intercooler upgrades
• Charge-air upgrades
• Exhaust modifications where legal
• Turbo-related upgrades
• Monitoring equipment

The exact combination should always be selected around the vehicle's intended use.

Engine Protection Still Comes First

Performance modifications on a diesel truck should never ignore reliability.

The 6.7L Powerstroke is a complex and expensive engine.

The turbocharger, cylinders, and internal components depend on clean intake air.

That is why S&B's published filtration figure is just as important as its airflow improvement.

39.05% more airflow gets attention.

99.42% filtration efficiency is what helps make the system appropriate for a truck expected to work.

Designed for the 2020–2027 Super Duty

Engine: 6.7L Powerstroke Diesel

Ford F-550 Super Duty

2020–2027 Ford F-550 Super Duty
Engine: 6.7L Powerstroke Diesel

Exact model year, engine, and emissions compatibility should be confirmed before ordering.

F-250 and F-350 Emissions Compliance

For the 2020–2026 Ford F-250 and F-350, the S&B intake is listed as 50-state compliant.

That is an important distinction for owners in states that follow California emissions requirements.

The compliance status changes for the 2027 model year, however.

2027 F-250 and F-350 CARB Status

For 2027 Ford F-250 and F-350 applications, the CARB Executive Order is currently listed as pending.

That means customers with a 2027 vehicle should verify the latest emissions approval status before purchase or installation where CARB compliance is required.

Do not assume the 2020–2026 approval automatically extends to the 2027 model year.

F-450 and F-550 Emissions Note

The F-450 and F-550 applications do not currently have a CARB Executive Order listed for this intake.

That may affect purchase or street-use eligibility in jurisdictions that require CARB-approved aftermarket emissions-related parts.

Owners of these models should verify their local requirements before ordering.

Why Model-Specific Emissions Status Matters

Two trucks can use the same 6.7L Powerstroke engine and still have different regulatory classifications.

That is why emissions compliance cannot be determined solely from engine size.

Vehicle class, model year, certification requirements, and Executive Order coverage all matter.

For this intake:

• 2020–2026 F-250/F-350: 50-state compliant.
• 2027 F-250/F-350: CARB EO pending.
• F-450/F-550: no CARB EO available.

Customers should order based on the specific truck rather than assuming all Super Duty applications have the same emissions status.

A Clean, Integrated Underhood Appearance

Performance is only part of what separates a well-designed intake from a universal system.

The enclosed S&B airbox gives the engine compartment a more complete appearance.

The filter, housing, inlet, and intake tube are designed as one system rather than looking like unrelated parts assembled together.

For a newer Super Duty, that integrated appearance helps the modification feel appropriate for the truck.

Good for Work Trucks and Enthusiast Builds

Not every S&B customer uses their Super Duty in the same way.

Some are dedicated tow vehicles.

Some are work trucks.

Some are daily drivers.

Others are enthusiast builds that happen to retain the ability to tow and haul.

The intake's combination of airflow, filtration, enclosed construction, and tunability makes it relevant across all of those categories.

The owner does not need to turn the truck into a dedicated performance build to benefit from reducing intake restriction.
