About This Product
A groundbreaking cold air intake featuring the patented Banks Air Mass Control Module. The electronic device allows our engineers to use the Banks SuperTube, a massive free-flowing intake tube, larger than stock and all competitors. No other cold air intake even comes close in size or airflow. Adds power, sharpens turbo response, and improves fuel economy. Beats stock and competitors in mass airflow, pressure retention, and dirt capacity. Provides a strong induction note.
Key Features
- Includes brand new Patented Banks Air Mass Control Module
- "Big Ass Filter" Extends service life and requires fewer cleanings
- Enclosed housing keeps out hot, power-robbing engine air
- Unique EPDM elbow with exclusive bellows for engine movement
- Oversized airbox increases cool air volume around filter
- Massive two piece XLPE airbox for easy servicing
- Connects to OEM hood and forward ram air scoops
- More audible and aggressive induction note
- Oiled Air Filter Element
- 5-year Limited Warranty
- No Check Engine Light
- US Patent #11,193,441
Specifications
Brand new for the 2020-2023 Duramax L5P platform, the Banks Ram-Air intake is a game-changer. With 2020 and up Duramax engines, GM has further tightened the allowable range for induction tuning. To counter this, Banks engineers have designed a new patented Air Mass Control Module that allows an intake design to go beyond these limitations for truly unmatched airflow performance.
With a Big-Ass filter, huge induction tube and a unique bellowed silicone coupler to allow for engine movement while tapering down to increase air density, your 6.6L engine will breathe easy and cleanly. Its enclosed airbox design keeps power-robbing heat away and attaches to the OEM hood and front ram air scoops for even better performance at speed on the highway. An extra side inlet opens up to the wheel well for fresh air and a strong induction note sound.
Why It's Better
Patented Electronics
The ECM (Engine Control Module) in your 2020-23 Duramax monitors air mass and pressure so closely that any deviation from stock results in a check engine light.
The new patented Banks Air Mass Control Module allows our engineers to design past this electronic limitation.
—U.S. Patent #11,193,441
Massive Airflow
In other words, all other competitive intakes must flow the same as stock past the Mass Air Flow sensor, whereas these stock airflow design constraints do not limit us.
Unrivaled Size and Capacity
The all-new Ram-Air cold air intake system's large organic shape eliminates all restrictions and turbulence to the turbo. The radical new design allows for a massive 58% gain in Mass Air Flow over the stock system.
The huge filter outlet smoothly tapers down providing the highest gains in air density.
Your Stock Intake is Restrictive
The 2020-23 Duramax OEM Air Box is a bulky multi-piece design with harsh bends, corners and is designed for dust collection, not performance. The air path is compromised by resonators and silencers in an effort to keep noise at a minimum.
While the factory design does have inlets that mate to the hood's air scoop, its square filter and S-shaped flow path induces turbulence and drag to the intake system lowering Mass Air Flow.
The Devil's in the Details
The new Banks Ram-Air system features a durable heat-resistant Cross-Linked Polyethylene enclosure with a smooth organic shape that maximizes cool air volume around the filter and maintains air density into the box itself.
The top hood scoop duct now dumps directly into the airbox chamber improving the ram-air effect at speed.
A side fender inlet away from engine heat further lowers the pressure drop in the system while also letting you hear your turbo better.
Exclusive Bellows Free Performance
Standard factory style bellows induce drag to the intake. This added turbulence affects the boundary layer on the inside of the intake reducing the effective diameter for air to flow through.
Banks' huge tapering intake elbow with exclusive bellows slide over the Banks Super-Tube allowing for free engine movement and unobstructed airflow into the turbo.
The elbow is made from EPDM synthetic rubber instead of silicone for greater environmental resistance and strength against damage or collapse under vacuum.
Air Mass Matters
The greater the air mass entering your engine, the less fuel your engine will consume.
That also means less engine heat going into the engine oil and coolant system since it is working less hard to make the same horsepower. In other words, improved fuel economy and less stress on the engine itself!
Yes, airflow (CFM) is important, but if the system flows more air, and that air is hot, you'll likely see a loss in horsepower and more stress on your engine.
Pressurized, cool, dense air is the winning combination. To learn more about air density, see this article.
A Big Filter — Engineered Right
The massive filter sits angled down in the air box to discourage dirt and debris from getting wedged between the pleats and Its massive 51in2 filter outlet Filter has over twice the airflow area of any competitor.
The Banks Super-Tube fits perfectly over the top of the filter which has an integrated collar to smoothly transition airflow from the air box and into the turbo with the lowest resistance and drag.
Bigger is Better When Properly Engineered
While other brands go for bragging rights for the "biggest" by cramming more pleats into their filters, they end up designing one that gets clogged faster and flows less air.
Just having a big looking filter, does not mean it will perform the best.
Banks massive filter has an optimized ratio of filter surface area, pleat count, and media thickness allowing it to outflow every other filter tested while breathing evenly from all sides. Banks wins again.
