Banks Power Ram-Air Cold Air Intake System

2013–2018 RAM 2500/3500 6.7L Cummins

Part #: 42255-D

Overview

The Banks Ram-Air Cold Air Intake System is engineered specifically for the 2013 to 2018 RAM 2500 and 3500 models equipped with the 6.7L Cummins engine. Designed to feed your engine cooler, denser outside air, this intake system enhances combustion efficiency, resulting in improved power output and better fuel economy. By replacing the restrictive factory intake, the Ram-Air system delivers up to 66% greater airflow, allowing your Cummins engine to breathe more freely under all driving conditions.

Ideal for diesel enthusiasts seeking reliable performance gains without sacrificing durability, this intake system is extensively tested and validated through advanced computational fluid dynamics, flowbench testing, and real-world vehicle trials. The result is a proven upgrade that helps your engine run cooler, cleaner, and more efficiently.

Key Features

The Banks Ram-Air Cold Air Intake System combines innovative design and high-quality components to maximize airflow and filtration efficiency. Key features include:

• Extensively tested and validated using CFD software, flowbench, and vehicle testing for proven performance
• Enclosed intake housing that isolates the filter from hot engine bay air, ensuring intake of cooler outside air
• Up to 66% greater airflow compared to the stock intake system for enhanced power and fuel economy
• Large, high-flow dry air filter element that maximizes filtration efficiency while extending service intervals
• Design accommodates engine movement to prevent damage and maintain reliable operation
• Helps reduce engine operating temperatures by supplying cooler air
• Durable construction designed to withstand harsh under-hood environments
• Includes a 5-year limited warranty for peace of mind

Construction & Design

The Banks Ram-Air Intake System features a robust, enclosed housing crafted to protect the air filter from heat soak and contaminants. The design ensures that only fresh, cooler outside air is drawn into the engine, which is critical for maintaining optimal combustion temperatures and efficiency. The dry filter element is engineered for high airflow and excellent filtration, reducing the frequency of cleanings and extending filter life. Additionally, the intake components are precision-engineered to accommodate engine movement and vibrations, preventing damage and ensuring a secure fit throughout the vehicle’s lifespan.

Performance & Sound

By increasing airflow by up to 66% over the stock intake, the Banks Ram-Air system improves throttle response and overall engine performance. Cooler, denser air promotes more efficient combustion, which can lead to noticeable gains in power and fuel economy. While designed primarily for performance and efficiency, the intake also contributes to a subtle enhancement in engine sound, delivering a deeper, more aggressive intake tone without excessive noise.

Installation & Fitment

The Banks Ram-Air Cold Air Intake System is designed as a direct-fit upgrade for 2013–2018 RAM 2500 and 3500 trucks with the 6.7L Cummins engine. Installation requires no major modifications and can typically be completed with basic hand tools. The system includes all necessary hardware and detailed instructions to ensure a straightforward installation process, allowing you to upgrade your intake quickly and confidently.
