Enhance your 2020-2023 GM 6.6L Duramax L5P 2500/3500's engine performance with the Banks Power 42266-D Ram-Air Intake System, featuring an advanced dry filter design. This system is crafted to overcome the restrictive airflow limitations set by GM for the L5P Duramax engines, thanks to a patented Air Mass Control Module by Banks. This innovative component permits the intake design to surpass factory restrictions, offering unparalleled airflow enhancement.

• Patented Banks Air Mass Control Module: Circumvents electronic airflow restrictions to prevent check engine lights.
• Unmatched Size & Capacity: Achieves a 58% increase in Mass Air Flow over the stock system, with a large organic-shaped airway that eliminates turbulence.
• Exclusive Design Features: A massive two-piece XLPE airbox for simple servicing, an oversized housing to boost cool air volume around the filter, and connection compatibility with OEM hood and front ram air scoops.
• Advanced Filtration: Utilizes a "Big Ass Filter" for a prolonged service life and minimal maintenance needs, alongside an EPDM elbow with a unique bellows design to facilitate engine movement without compromising airflow.

The state-of-the-art Ram-Air intake system not only ensures a significant airflow increase but also integrates seamlessly with your vehicle's existing components for enhanced performance at highway speeds. The incorporation of a supplementary side inlet, which opens to the wheel well, introduces an aggressive induction note along with additional fresh air intake.

Contrary to the restrictive nature of the OEM air box, with its inefficient flow path and design geared towards minimizing engine noise rather than maximizing performance, the Banks system excels in delivering high-performance results. Its streamlined air path directly combats the stock system's inefficiencies by avoiding unnecessary silencers and resonators that hinder performance.

The true innovation lies in the system's ability to provide pressure-cooled, dense air to your engine, optimizing fuel economy and reducing engine strain. This not only leads to enhanced horsepower but also contributes to the longevity and efficiency of your vehicle's engine by minimizing heat transfer to the coolant system and oil.

Key Features Include:

• A more noticeable and aggressive induction sound
• An enclosed airbox design that isolates it from engine heat, ensuring only cool air reaches your engine
• A unique EPDM elbow, replacing traditional silicone for improved resistance and airflow, free from the drag typically induced by factory-style bellows

By installing the Banks Power 42266-D Ram-Air Intake System, you're setting your Duramax L5P on a path to remarkable performance gains, characterized by an aggressive engine note, superior airflow, and an overall more efficient, powerful driving experience.
