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. Banks Ram Intakes have Massive Airflow This is why 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 Banks intake designs. Your Stock Intake Is Restrictive The 2020-23 Chevy / GMC HD 6.6L 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. Exclusive To Banks 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.* CONTACT US FOR BANKS TUNERS C hec k Out our Awesome Feedback RETURN POLICY We will exchange at no cost to our Customer, if we sent the wrong shipment or manufacturer defect.
