Banks Big Ass L5P Filter - Massive airflow design with patented electronics
A true next-generation intake design using the patented Banks Air Mass Control Module to break free from previous design limitations. Big-Ass filter provides maximum filtration with low resistance and is sealed off from power-robbing engine bay heat. Side fender cold air inlet gives a strong induction note. Increases air density as the intake tube tapers down improving engine efficiency and performance while reducing soot and engine stress.
Brand new for the 2020-2023 Duramax L5P platform, the Banks Big Ass Ram-Air intake is going to be a game-changer. With 2020 and up Duramax engines, GM has further tightened the allowable range for induction tuning, Banks engineers have designed a new patented device that allows us to design an intake beyond these limitations for truly unmatched airflow performance.
With the largest filter and induction tube and a unique bellowed silicone coupler to allow for engine movement, your 6.6L engine will breathe easy and cleanly with added air density, horsepower, and torque. Its fully enclosed airbox design keeps power robbing heat away while still attaching to the OEM front ram air scoop through the hood for even better performance at speed on the highway.
Banks in-house engineering teams use sensors throughout the engine to determine the best source for cool exterior air. With its unrivaled size, the Ram-Airs smooth organic shape eliminates all restrictions and turbulence to the turbo. Unrivaled in size, the Ram-Airs smooth organic shape eliminates all restrictions and turbulence to the turbo. The oversized filter has greater dust holding ability and the huge inlet tapers down increasing air density even more into the turbo. The Ram-Airs large shape has less drag than a long narrow tube which reduces pressure drop to the turbo.
Competitive intake systems all suffer the same limitation, when they flow more air than stock, it sets a Check Engine Light. Every other intake on the market has to neck down to the OEM size reducing performance. Those days are no more, the brand new Banks Air Mass Control Module allows our engineers to design past this limitation and create truly the largest intake system physically possible.
