AWE S-FLO Intake Upgrades for FL5 Type R & DE5 Type S | X-PH
27th Oct 2026
The Honda Civic Type R FL5 and Acura Integra Type S DE5 already combine impressive turbocharged performance with some of the most capable front-wheel-drive chassis available today.
But like any turbocharged performance platform, the path air takes before reaching the turbocharger matters.
AWE has approached that part of the FL5 and DE5 with a modular intake system that allows owners to improve the turbo inlet independently or upgrade the complete intake tract with a sealed carbon fiber airbox.
Extreme Power House now offers two AWE intake upgrades for the FL5 Civic Type R and DE5 Integra Type S:
- AWE Carbon Turbo Inlet Tube – 2660-11114
- AWE S-FLO Carbon Intake – 2660-11115
The two products are designed to work together, but owners do not necessarily have to purchase the entire system at once. AWE specifically developed the architecture so the carbon turbo inlet can work with the factory airbox, while the S-FLO carbon airbox can also work with the factory turbo inlet. Pair the two together and they form the complete AWE S-FLO intake system.
That modular approach gives FL5 and DE5 owners an upgrade path that can grow alongside the rest of the vehicle.

AWE Carbon Turbo Inlet Tube for FL5 Civic Type R & DE5 Integra Type S
The first component focuses on one of the most important sections of a turbocharged intake system:
The passage immediately feeding the turbocharger.
The AWE Carbon Turbo Inlet Tube replaces the factory inlet with a larger-flowing carbon fiber component engineered to reduce restriction before the turbo.
According to AWE, the inlet provides a 39% larger inlet cross-sectional area compared with the factory component.
For owners interested in improving airflow without replacing the complete factory intake system immediately, that makes the turbo inlet an especially interesting place to start.
Why the Turbo Inlet Matters
The turbocharger can only work with the air supplied to it.
Before the compressor can increase pressure, incoming air has to travel through the airbox, intake tract, and turbo inlet.
Restrictions in that path can make it more difficult for the turbocharger to draw the airflow demanded by the engine.
The AWE inlet addresses that portion of the system through a larger internal passage.
Instead of focusing purely on appearance, the carbon inlet is designed around increased airflow capacity.
AWE states that the cross-sectional area is 39% larger than stock, giving incoming air a less restrictive route toward the turbocharger.
Carbon Fiber With a Performance Purpose
Carbon fiber is often used purely as a styling material.
Here, it forms a major part of the intake tract itself.
The AWE system uses genuine 2x2 carbon fiber construction with UV-stabilized resin and a protective clear coat, combining the visual appeal of exposed carbon with an intake component designed around airflow.
Open the hood of an FL5 Type R or DE5 Type S and the inlet becomes a noticeable engine-bay upgrade.
But the larger internal passage is what gives it its performance-focused purpose.
39% Larger Inlet Cross-Section
AWE's published specification is one of the most important numbers associated with the inlet:
39% larger inlet cross-sectional area compared with the factory inlet.
That does not mean a 39% horsepower increase.
It means the physical airflow passage through the inlet is substantially larger than the original component.
The actual power benefit will depend on the rest of the intake system, ECU calibration, turbocharger, fuel, and overall vehicle setup.
For a turbocharged engine, however, reducing restriction before the compressor can be a valuable supporting modification.
Works With the Factory Airbox
One of the biggest advantages of the AWE design is that owners do not have to replace everything at once.
The Carbon Turbo Inlet Tube is compatible with the factory airbox.
That means an owner can upgrade the inlet first while retaining the original filtration and airbox assembly.
For someone building the vehicle gradually, this provides a logical first stage.
Install the larger inlet now.
Add the AWE S-FLO Carbon Airbox later.
The components were developed to work together when the owner is ready to complete the system.
Compatible With the AWE Carbon Airbox
The inlet is also designed to connect directly to AWE's S-FLO Carbon Airbox.
With both components installed, the system becomes the full AWE S-FLO intake configuration.
That means the airflow improvements are addressed at two major points:
The airbox and filter at the beginning of the intake tract.
And the larger turbo inlet immediately before the turbocharger.
Rather than assembling unrelated aftermarket components, owners can build a complete intake using parts designed as one modular system.
Compatible With Factory-Fitment Turbochargers
AWE lists the Carbon Turbo Inlet Tube as compatible with all factory-fitment turbochargers for the intended FL5 and DE5 applications.
That makes it suitable for cars retaining the original turbocharger without requiring the owner to move immediately into a larger-turbo setup.
Designed With Future Turbo Upgrades in Mind
AWE also adds an important feature for owners planning more serious modifications.
The system uses a removable aluminum turbo flange and coupler that can accommodate larger turbochargers with larger inlet dimensions.
That gives the inlet additional flexibility as the build progresses.
A car may begin on the factory turbo today.
Later, it may receive a higher-flowing replacement.
Instead of making the entire inlet obsolete, AWE has designed the turbo-side connection with upgraded configurations in mind.
Machined Aluminum Turbo Flange
At the turbo connection, AWE uses a machined aluminum flange.
The flange provides a durable connection point while supporting straightforward installation.
Combining the aluminum flange with the carbon intake body also lets AWE use each material where it makes the most sense: lightweight carbon for the primary intake tract and machined metal at the high-stress turbo connection.
Application-Specific Silicone Coupler
The inlet also includes an application-specific silicone coupler designed to connect with either the factory airbox or AWE's carbon airbox.
That reinforces the modular nature of the system.
Owners can configure the intake according to their current build rather than being forced into one complete package from day one.
A Strong Supporting Modification for Future Builds
For a relatively stock Type R or Integra Type S, the AWE turbo inlet can provide a larger-flowing replacement for the original component.
For a more extensively modified vehicle, its value can become even greater.
Future upgrades may include:
- ECU calibration
- Intercooler upgrades
- Exhaust modifications
- Higher boost
- Fuel-system upgrades
- Larger turbochargers
- Complete intake upgrades
As airflow demand increases, reducing restriction before the turbo becomes increasingly relevant.

AWE S-FLO Carbon Intake for FL5 Civic Type R & DE5 Integra Type S
For owners who want the complete intake package rather than upgrading only the turbo inlet, AWE offers the S-FLO Carbon Intake, Part Number 2660-11115.
The complete system combines:
- AWE Carbon Airbox
- AWE S-FLO Filter
- AWE Carbon Turbo Inlet Tube
Together, these components create a full intake path designed around increased filter area, improved inlet airflow, precision MAF integration, and premium carbon fiber construction.
Up to 20 WHP and 16 LB-FT at the Wheels
When installed as the complete S-FLO system, AWE reports maximum dyno-proven gains of up to 20 horsepower and 16 lb-ft of torque at the wheels when used with 91-octane software.
Those figures apply to the complete intake configuration, not the Turbo Inlet Tube by itself.
That distinction is important.
The complete system addresses airflow from the filter through the airbox and down into the turbo inlet.
As always, actual output can vary based on vehicle condition, fuel, calibration, environmental conditions, and supporting modifications.
No Tune Required
Despite the larger-flowing design, AWE states that no tune is required to install and operate the S-FLO system.
That makes the intake accessible to owners who want an airflow upgrade without immediately recalibrating the ECU.
It also means the intake can serve as an early modification before additional tuning or performance hardware is added later.
AWE No Check Engine Light Guarantee
AWE also backs the system with its No Check Engine Light Guarantee.
This is particularly relevant on modern vehicles where changes to airflow around the mass airflow sensor can cause calibration issues if the intake geometry is not engineered correctly.
AWE's design places significant emphasis on maintaining consistent airflow across the MAF sensor.
85% More Filter Surface Area
The carbon airbox and S-FLO Filter provide an 85% increase in filter surface area compared with the factory configuration, according to AWE.
More filter area gives the intake additional surface through which incoming air can pass.
That works alongside the larger turbo inlet to improve the overall airflow capacity of the system.
Again, this should not be confused with an 85% horsepower increase.
It is specifically a measurement of filter surface area.
Fully Sealed Carbon Fiber Airbox
Rather than using a completely open filter sitting inside the engine compartment, AWE designed the S-FLO with a fully sealed carbon fiber airbox.
The airbox integrates with the vehicle's factory inlet ducting, preserving a structured path for incoming air while replacing the factory enclosure with a larger performance-oriented design.
For enthusiasts who prefer a more OEM-style enclosed intake instead of an exposed filter arrangement, this is an important feature.
Precision 80 mm Aluminum MAF Housing
Modern airflow meters need stable and predictable airflow across the sensor.
AWE incorporates a precision-engineered 80 mm aluminum MAF housing into the S-FLO airbox.
The housing is designed to provide consistent airflow across the sensor, helping the ECU accurately monitor the air entering the engine.
This is a crucial engineering detail on a modern turbocharged platform.
Increasing airflow is useful.
Maintaining proper sensor behavior while doing it is equally important.
Washable, Oil-Less S-FLO Filter
The system uses AWE's washable, oil-less S-FLO Filter.
Because the filter does not require oiling, owners do not need to apply filter oil during routine servicing.
The reusable design also means the filter can be cleaned and returned to service rather than automatically being discarded each time maintenance is required.
Factory Inlet Ducting Is Retained
The S-FLO Carbon Airbox connects to the factory inlet ducting.
That allows the upgraded airbox to use the vehicle's existing front-end air path rather than abandoning the OEM duct arrangement.
This helps make the system feel integrated into the original vehicle rather than simply adding a universal open-filter setup inside the engine bay.
Genuine 2x2 Carbon Fiber Construction
Both the airbox and inlet bring a substantial visual upgrade to the engine bay.
AWE uses genuine 2x2 carbon fiber with UV-stabilized resin and a protective clear coat.
That gives the system a finish appropriate for the Type R and Type S while helping protect the carbon surface over time.
For owners already adding carbon fiber exterior or engine-bay components, the intake can become one of the dominant visual pieces under the hood.
Uses Factory Mounting Locations
The S-FLO system installs using factory mounting locations, helping keep the installation vehicle-specific and avoiding unnecessary modifications to the engine bay.
AWE also lists the system with its Perfect Fitment Guarantee.
The Real Advantage: The Airbox and Inlet Work Together
The complete S-FLO system addresses two separate restrictions.
At the beginning of the intake tract, the larger filter and carbon airbox increase available filter area.
At the turbo end, the carbon inlet provides a 39% larger inlet cross-section.
The result is a complete intake architecture rather than a single isolated component.
That is where the two products in this article connect.
The Turbo Inlet Tube can stand on its own.
But combine it with the S-FLO Carbon Airbox and the owner gets the complete AWE intake system.

Turbo Inlet Only or Complete S-FLO Intake?
Choosing between the two depends on where the vehicle is in its build.
Choose the AWE Carbon Turbo Inlet Tube If:
You want to retain the factory airbox while reducing restriction closer to the turbocharger.
You may also prefer the inlet if you are building the car in stages or preparing for a future turbocharger upgrade.
Because the AWE inlet can work with either the factory airbox or AWE Carbon Airbox, installing it first does not prevent you from completing the S-FLO setup later.
Choose the Complete AWE S-FLO Carbon Intake If:
You want AWE's full intake solution from the factory duct to the turbo inlet.
The complete configuration adds:
- 85% more filter surface area
- Fully sealed carbon airbox
- Washable oil-less S-FLO Filter
- 80 mm aluminum MAF housing
- Carbon Turbo Inlet Tube
- 39% larger inlet cross-section
- Manufacturer-reported gains of up to 20 WHP and 16 WTQ with 91-octane software
For owners already planning to upgrade both pieces, the full system provides the most complete AWE airflow package.
Built for Both FL5 and DE5
Both products are designed for:
Honda Civic Type R – FL5
and
Acura Integra Type S – DE5.
That shared compatibility makes sense because the two cars use closely related turbocharged performance architecture, but exact chassis and vehicle configuration should still be confirmed before ordering.
Compatibility should never be assumed for earlier Civic Type R, Integra, or other Honda/Acura applications simply because they use related engine families.
A Strong Upgrade Path for the FL5 and DE5
The biggest advantage of AWE's design may be its modularity.
Owners do not need to decide between doing nothing and buying an entire intake package immediately.
The build can progress in stages.
Start with the Carbon Turbo Inlet Tube.
Keep the factory airbox.
Later, add the S-FLO Carbon Airbox.
Or install the complete system from the beginning and gain the benefits of both the larger filter area and larger turbo inlet passage.
That approach makes the system relevant to several types of builds, from lightly modified street cars to vehicles preparing for more substantial turbo and tuning upgrades.
Upgrade Your Civic Type R or Integra Type S at Extreme Power House
The FL5 Civic Type R and DE5 Integra Type S already provide an excellent foundation for performance upgrades.
AWE's modular S-FLO system targets one of the first areas every turbocharger depends on: the air entering the compressor.
The AWE Carbon Turbo Inlet Tube provides a 39% larger inlet cross-sectional area, compatibility with the stock or AWE airbox, and provisions for future larger-turbo configurations.
The complete AWE S-FLO Carbon Intake adds a sealed carbon airbox, 85% more filter surface area, an 80 mm aluminum MAF housing, a washable oil-less filter, and the larger carbon turbo inlet in one coordinated package. AWE reports maximum gains of up to 20 WHP and 16 WTQ at the wheels with 91-octane software, while requiring no tune for installation.
Whether you want to start with the inlet or upgrade the complete intake path, both options give FL5 and DE5 owners a performance-focused route forward.
