aFe Momentum HD Cold Air Intake System

2010–2012 Dodge Ram 2500 / Ram 3500 5.7L & 6.7L Cummins

Part #: 51-72004

Overview

The aFe Momentum HD Cold Air Intake System is a precision-engineered performance upgrade designed specifically for 2010 to 2012 Dodge Ram 2500 and Ram 3500 trucks equipped with 5.7L or 6.7L Cummins engines. This system replaces the restrictive factory airbox and filter with a high-flow, sealed intake that draws in cooler, denser air to enhance combustion efficiency. Ideal for truck owners seeking improved horsepower, torque, and throttle response, the Momentum HD delivers consistent power gains and better fuel economy without compromising engine protection or requiring complex modifications.

Built for durability and ease of installation, this intake system maintains a clean, factory-like appearance under the hood while maximizing airflow and filtration. It is an excellent upgrade for daily drivers, work trucks, and enthusiasts who want a reliable, straightforward performance enhancement.

Key Features

The Momentum HD Cold Air Intake System incorporates advanced engineering and premium materials to optimize airflow and filtration efficiency. Key features include:

• Custom CAD-designed roto-molded housing made from heat-resistant black cross-linked polyethylene for superior thermal insulation
• Large clear sight window for easy filter inspection without removing the airbox
• High-quality billet aluminum crankcase fitting for simple, secure installation
• CAD-designed, dyno-tuned roto-molded intake tube for maximum power gains and perfect fitment
• High-quality CAD air scoop that channels cool ambient air directly to the performance air filter
• Sealed intake system utilizing a radial flow Pro DRY S performance air filter with three oil-free synthetic media layers
• Premium stainless steel clamps and silicone couplings for durable, secure connections
• Designed around the largest possible filter to maximize airflow and filtration capacity
• Fewer parts for a quick, hassle-free installation

Construction & Design

The Momentum HD intake system features a rugged roto-molded housing constructed from black cross-linked polyethylene, chosen for its excellent heat resistance and durability. This single-piece housing design minimizes air leaks and heat soak by eliminating multiple components and joints. The intake tube is precision CAD-designed and roto-molded from high-quality plastic, ensuring a smooth airflow path that has been dyno-tuned for optimal performance.

Additional components include a billet aluminum crankcase fitting and a specially designed air scoop that efficiently directs cool ambient air to the filter. The housing’s large clear sight window allows for quick visual filter checks without disassembly, enhancing convenience. Premium stainless steel clamps and silicone couplings provide a secure, long-lasting seal capable of withstanding engine bay temperatures and vibrations.

Performance & Sound

The aFe Momentum HD Cold Air Intake System improves engine breathing by delivering cooler, denser air to the combustion chamber. This results in noticeable gains in horsepower and torque, along with improved throttle response. The radial flow Pro DRY S performance air filter, featuring three oil-free synthetic layers, offers approximately twice the airflow of a stock filter while maintaining excellent filtration efficiency of 99.2%.

While primarily designed for performance and efficiency, this intake system also enhances engine sound with a more aggressive tone during acceleration, enriching the driving experience without excessive noise.

Installation & Fitment

Installation is straightforward and can typically be completed in under an hour using basic hand tools. The system is designed to replace the factory air filter and airbox without any cutting, drilling, or modifications. It installs easily in place of the stock components, using supplied stainless steel hardware for secure mounting.

The one-piece housing seals against the hood with flexible rubber trim to isolate the filter from engine heat, ensuring consistent intake of cool air. This intake system is specifically engineered to fit 2010 to 2012 Dodge Ram 2500 and Ram 3500 trucks with 5.7L and 6.7L Cummins engines, guaranteeing a precise fit and seamless integration with factory components.
