Product Description

Most factory intakes pull in warm engine bay air and restrict airflow, which limits both power and efficiency—especially under load. This Banks Ram-Air system fixes that by sealing the intake and feeding it cooler outside air, giving your engine a denser charge to work with. With up to 35% more airflow, you get better throttle response, improved fuel economy, and noticeable gains in horsepower and torque, especially when paired with other performance upgrades.

Banks didn’t just design this to flow better—they made sure it works in the real world. Every system goes through simulation, flowbench, dyno, and on-road testing before it ever gets released. The oversized filter keeps airflow steady even as it collects dirt, while the built-in bellows allows for engine movement without stressing components. It’s a well-rounded upgrade that improves power, efficiency, and durability all at once—exactly what you want from a properly engineered intake system.
