Helps engine produce horsepower at lower RPM
Not only does power come on sooner with the Ram-Air intake, but the turbo spins nearly 3,000 RPM slower increasing its efficiency and longevity. Turbo life is increased because it’s spinning millions of revolutions less over its lifetime.
Patented Electronics
The Banks Crankcase Ventilation Control Module is a patented electronic device designed to work with the Banks Air Mass Control Module. Developed in-house and manufactured locally, the Crankcase Ventilation Control Module allows for modifications to the intake system without triggering diagnostic trouble codes like P04DB (Crankcase Vent System Disconnected) or related check engine lights and reduced engine power modes that plague other aftermarket intakes systems.
Late-model 2025+ Duramax trucks feature ultra-stringent ECM oversight of crankcase pressure, ventilation flow, and blow-by gases via integrated sensors in the CCV system. Any non-stock alteration—like rerouting for better oil separation, increased ventilation capacity to handle higher boost/performance, or integration with high-flow intakes—risks the ECM detecting "out-of-range" pressure or flow deviations. These deviations result in a check engine light to protect emissions compliance.
Massive Airflow
Unrivaled Size and Capacity
The oversized filter has greater dust capacity giving you more miles between services and flows freely long after stock and competitors are clogged with debris.
The huge filter outlet smoothly tapers down providing the highest gains in air density.
Your Stock Intake is Restrictive
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 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
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
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 massive51in2filter outlet Filter has overtwicethe airflow area of any competitor.
Bigger is Better When Properly Engineered
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.
