aFe Momentum HD Cold Air Intake System
2003–2007 Dodge Ram 2500 / Ram 3500 5.7L / 6.7L
Part #: 51-72002
Overview
The aFe Momentum HD Cold Air Intake System is a precision-engineered upgrade designed specifically for 2003 to 2007 Dodge Ram 2500 and Ram 3500 trucks equipped with 5.7L or 6.7L engines. This intake system replaces the restrictive factory airbox and filter with a high-flow, sealed assembly that draws in cooler, denser air from outside the engine bay. By improving airflow and combustion efficiency, it delivers noticeable gains in horsepower, torque, and fuel economy without requiring extensive modifications or tuning.
Ideal for both daily drivers and performance enthusiasts, the Momentum HD system offers a cost-effective, reliable way to enhance your truck’s power and throttle response. Its straightforward installation process can be completed in under an hour using basic hand tools, making it accessible for DIYers and professional installers alike.
Key Features
The Momentum HD Cold Air Intake System incorporates advanced design elements and premium materials to maximize airflow, filtration, and durability. Key features include:
- Pro DRY S air filter media with 360-degree radial flow for superior filtration and unrestricted airflow
- Three-layer progressive synthetic filter media that is washable and reusable for long-term performance
- Massive 1,000 CFM air filter with a large 6-inch flange and inverted design for optimal air intake
- Durable 2-ply reinforced silicone hump coupler ensuring a secure, leak-free connection
- Stainless steel T-bolt clamp for corrosion-resistant, reliable fastening
- Built-in sight glass for quick and easy inspection of the air filter condition
- Auxiliary air scoop with urethane plug to enhance airflow and protect the filter
- Unique patent-pending housing-to-filter interface that improves airflow efficiency
- Backed by a 2-year limited warranty reflecting aFe’s commitment to quality and performance
Construction & Design
The Momentum HD system features a one-piece sealed airbox and heat shield constructed from rugged 16-gauge powder-coated steel, providing excellent durability and resistance to heat and corrosion. The airbox seals tightly against the hood with a flexible rubber trim, effectively isolating the air filter from engine heat and allowing it to draw in cooler ambient air. This design helps maintain consistent intake temperatures, which is critical for maximizing engine performance.
The intake tube incorporates a specially developed three-angle velocity stack that smooths airflow transition from the filter to the engine, reducing turbulence and maximizing volumetric efficiency. All included hardware is stainless steel, ensuring long-lasting strength and a professional finish.
Performance & Sound
By increasing the volume of cooler, denser air entering the engine, the Momentum HD Cold Air Intake System enhances combustion efficiency. This results in improved throttle response and potential gains in horsepower and torque. Additionally, the system produces a more aggressive intake sound that adds to the driving experience without excessive noise, striking a balance between performance and comfort.
Installation & Fitment
Installation of the aFe Momentum HD Cold Air Intake System is straightforward and requires no cutting, drilling, or permanent modifications. It replaces the factory airbox and filter with the Momentum HD assembly using supplied stainless steel hardware and detailed instructions. Most installations can be completed in under an hour with basic hand tools, making it accessible for both professional installers and DIY enthusiasts.
This intake system is specifically designed to fit 2003 through 2007 Dodge Ram 2500 and Ram 3500 models with 5.7L or 6.7L engines, ensuring a precise fit and seamless integration with factory components.

What does the Available to Promise date mean?
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!
