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.

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.
