The Banks Ram-Air Cold Air Intake System is engineered specifically for the 2003 to 2007 Dodge Ram 2500 and 3500 models equipped with the 5.9L Cummins engine. Designed to replace the factory air intake, this system significantly improves airflow, delivering up to 62% better flow than the stock setup. It is ideal for diesel truck owners seeking enhanced engine efficiency, reduced exhaust gas temperatures, and improved fuel economy without sacrificing reliability or durability.
Featuring an enclosed cold-air box and a large oiled cotton gauze filter, the Ram-Air system draws in cooler, denser air from outside the engine bay. This cooler air helps reduce smoke emissions and lowers engine operating temperatures, contributing to a cleaner-running engine and better overall performance. The system’s robust design ensures long service life and fewer filter cleanings compared to conventional intakes.
The Banks Ram-Air Intake System combines advanced engineering and practical design to maximize airflow and engine protection. Key features include:
The Banks Ram-Air system is built with durability and performance in mind. The intake features a rugged enclosed housing that protects the filter from heat soak and contaminants. The large 4-1/2" bellows are uniquely designed to flex with engine movement, preventing stress and potential damage to the intake components. The oiled cotton gauze filter media provides excellent airflow while effectively capturing dirt and debris, extending filter life and maintaining engine protection.
Every component is engineered to meet or exceed OEM standards, ensuring a reliable fit and long-lasting service even under demanding conditions typical of heavy-duty diesel trucks.
By delivering cooler, denser air to the engine, the Banks Ram-Air Intake System helps reduce exhaust gas temperatures and lowers black smoke emissions, contributing to cleaner combustion. The increased airflow supports improved throttle response and can enhance fuel efficiency. While designed primarily for performance and efficiency, the intake also produces a subtle, aggressive induction sound that enhances the driving experience without being intrusive.
This intake system is designed as a direct bolt-on replacement for the factory air intake on 2003–2007 Dodge Ram 2500 and 3500 trucks with the 5.9L Cummins engine. Installation requires no permanent modifications or cutting, making it accessible for DIY enthusiasts with basic hand tools. The included flexible bellows accommodate engine movement, ensuring a secure fit and preventing stress on the intake components during operation.
The Banks Ram-Air Cold Air Intake System is perfect for Dodge Ram 2500 and 3500 owners who want to improve their truck’s airflow, reduce exhaust gas temperatures, and increase fuel economy without compromising reliability. It is especially suited for diesel enthusiasts who demand durable, high-performance parts that withstand heavy-duty use and deliver measurable gains in power and efficiency.
Banks Power develops emissions-compliant performance parts for diesel and gas trucks, SUVs, and tow rigs—focused on airflow, efficiency, and reliable power.

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!
