Does Not Fit 2025 - See Fitment Note

The Ram-Air intake system for the 2024 Duramax 6.6L helps the engine produce horsepower at lower RPM, sharpens turbo response, and improves fuel economy by improving air mass flow to the turbo. This is made possible by our patented electronics. Meanwhile, all competitors must retain near stock airflow or risk setting a check engine light.

Helps engine produce horsepower at lower RPM

Thanks to a 45% reduction in pressure loss over the stock intake, air mass is increased into the turbo inlet. This denser air makes the turbo's job easier. Turbo lag is reduced and boost comes on sooner, widening the engine's working RPM range.

Wheel Horsepower

Wheel Torque

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 ECM (Engine Control Module) in your 2024 Duramax monitors air mass and pressure so closely that any deviation from stock results in a check engine light

Banks Air Mass Control Module used in the 2024 Duramax L5P

The new patented Banks Air Mass Control Module allows our engineers to design past this electronic limitation.

Massive Airflow

In other words, all other competitive intakes must flow within a narrow airflow window near stock levels 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 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

The Duramax OEM air filter housing 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 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.

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

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.

Fitment Note

Ram-Air Intake not compatible with 2025 Duramax. GM added a PCV sensor for the '25+ model year. The new Ram-Air Intake for the '25 includes both the patented Banks Air Mass Control Module and a new Banks Crankcase Ventalation Control Module. Avaliable Now SKU #42297.
