Product Overview

Upgrade your Cummins-powered Dodge Ram with a high-performance cold air intake engineered to unlock your engine’s true potential. This intake system is designed specifically for the 5.9L inline-6 diesel engine, delivering increased airflow while maintaining excellent filtration efficiency.

By replacing the factory air box with a free-flowing aluminum intake system, your engine breathes cooler, denser air—resulting in noticeable gains in throttle response, horsepower, and torque. Whether you use your Ram for towing, daily driving, or work applications, this intake improves overall drivability while adding a bold, sporty engine sound.

The included washable air filter reduces long-term maintenance costs and ensures consistent performance over time. Built with durability in mind, the T304 aluminum piping resists corrosion and heat soak, making it ideal for demanding diesel environments.

Why Upgrade Your Factory Air Box?

• Improved horsepower and torque output

• Faster acceleration and throttle response

• Potential gains in fuel efficiency

• Deeper, more aggressive engine sound

• Cleaner, sportier engine bay appearance

• Reusable filter saves money over disposable replacements

Installation Notes

Installation requires basic tools such as screwdrivers and socket wrenches. The process involves removing the factory air box and installing the intake components in its place. Many customers complete installation within one hour.

For best results, it is recommended to briefly disconnect the battery after installation to allow the engine control unit (ECU) to adapt to the increased airflow. Always disconnect the battery when performing engine work.
