The Banks Ram-Air Cold Air Intake System is engineered specifically for the 2003 to 2007 Dodge Ram 2500 and 3500 equipped with the 5.9L Cummins engine. Designed to replace the factory intake, this system delivers significantly improved airflow, enhancing engine efficiency and performance without sacrificing reliability. Ideal for diesel enthusiasts seeking cooler intake temperatures, reduced exhaust gas temperatures, and improved fuel economy, the Ram-Air system combines durability with advanced airflow technology.
By drawing in cooler, denser outside air through an enclosed cold-air box, the Banks Ram-Air system reduces smoke and lowers exhaust gas temperatures, contributing to cleaner combustion and better mileage. Its robust design accommodates engine movement, ensuring long-lasting service life and consistent performance under demanding conditions.
Every aspect of the Banks Ram-Air Cold Air Intake System is crafted to maximize airflow and filtration efficiency while maintaining factory-level durability. Key features include:
The Banks Ram-Air system features a rugged, enclosed air filter housing that protects the intake from heat soak and contaminants. The housing is engineered with large side and bottom inlets to maximize cold air capture while maintaining a sealed environment. The intake incorporates a unique 4-1/2" flexible bellows section, an industry-exclusive design that allows the system to move with the engine, preventing stress and potential damage to components.
The dry cotton gauze filter element is designed for high-flow filtration, capturing the most dirt and debris while requiring fewer cleanings compared to conventional filters. This combination of materials and design ensures durability and consistent performance in harsh diesel truck environments.
By significantly increasing airflow—up to 62% over stock—the Banks Ram-Air Cold Air Intake System enhances engine breathing, which can lead to improved throttle response and overall power delivery. Cooler intake air reduces exhaust gas temperatures and black smoke emissions, contributing to cleaner combustion and better fuel efficiency. While designed primarily for performance and efficiency, the system maintains a subtle, refined intake sound that complements the Cummins diesel’s natural tone without excessive noise.
This intake system is a direct-fit upgrade for 2003–2007 Dodge Ram 2500 and 3500 models equipped with the 5.9L Cummins engine. Installation requires no permanent modifications and utilizes factory mounting points and hardware for a straightforward bolt-on process. The flexible bellows accommodate engine movement, ensuring a secure fit and long-term durability without the need for additional adjustments.
The Banks Ram-Air Cold Air Intake System is perfect for Dodge Ram 2500 and 3500 owners who want to improve their 5.9L Cummins diesel’s airflow, reduce exhaust gas temperatures, and increase fuel economy without compromising reliability. It is especially suited for daily drivers, towing enthusiasts, and diesel performance seekers who demand a durable, factory-quality intake upgrade that delivers measurable gains and extended filter service intervals.

ETA stands for Estimated Time of Arrival. The date shown is calculated using our Available-to-Promise (ATP) system, which tracks real-time supplier commitments to determine when a product is expected to be available for delivery. Specifically, the date is calculated by adding 9 business days from the date a supplier has committed to ship the product, representing a worst-case scenario for when we can expect to receive inventory.
Please note: The ETA is an estimate, not a guarantee. While we work closely with our suppliers to keep dates as accurate as possible, delays due to shipping carriers, weather, customs, or supplier-side issues may occasionally push the actual arrival beyond the date shown. Likewise, inventory may arrive sooner than the ETA in many cases. If you would like to be notified for when this item arrives, sign up for our back in stock notifications!
