aFe Momentum HD Cold Air Intake System

2013–2018 Ram 2500/3500 6.7L Cummins Diesel

Part #: 51-72005

Overview

The aFe Momentum HD Cold Air Intake System with Pro DRY S Filter is a precision-engineered performance upgrade designed for 2013–2018 Ram 2500 and 3500 trucks equipped with the 6.7L Cummins diesel engine. This intake system replaces the factory airbox and filter with a sealed, one-piece aluminum housing and a high-flow synthetic air filter, delivering cooler, denser air to the engine. The result is improved combustion efficiency, enhanced throttle response, and potential gains in horsepower and fuel economy.

Ideal for diesel enthusiasts and daily drivers alike, the Momentum HD system offers a straightforward installation without the need for cutting or drilling. Its sealed design effectively isolates the intake from engine heat, ensuring consistent delivery of fresh air for reliable performance under all driving conditions.

Key Features

Engineered to optimize airflow and filtration, the aFe Momentum HD Cold Air Intake System combines durable materials with advanced design elements to enhance your Ram’s performance:

• Massive 1,000 CFM Pro DRY S synthetic air filter for maximum airflow and superior filtration
• One-piece sealed aluminum airbox with built-in sight window for quick filter inspection
• 3-angle velocity stack engineered to smooth airflow transition and reduce turbulence
• Flexible rubber trim seals the airbox against the hood, isolating intake air from engine heat
• Durable 16-gauge powder-coated steel heat shield for corrosion resistance and longevity
• Washable and reusable Pro DRY S filter media for easy maintenance and extended service life
• Oil-free synthetic media with progressively finer mesh layers for enhanced filtration efficiency
• Polyurethane flange with integrated bumps ensures a tight, leak-free seal over the filter’s lifespan
• Quality stainless steel hardware included for secure, hassle-free installation

Construction & Design

The Momentum HD intake system features a rugged, one-piece airbox and heat shield constructed from 16-gauge powder-coated steel, providing excellent durability and resistance to corrosion. The lightweight black aluminum housing incorporates a built-in sight window, allowing for quick visual inspection of the air filter without removal. The intake tube’s specially engineered 3-angle velocity stack optimizes airflow by smoothing the transition from the filter to the intake manifold, reducing turbulence and improving volumetric efficiency.

Flexible rubber trim lines the top of the airbox, sealing tightly against the hood to isolate the intake from engine heat and ensure the filter draws in cooler ambient air. This thoughtful design helps maintain consistent performance and throttle response in all conditions.

Performance & Sound

By increasing the volume of cooler, denser air entering the engine, the aFe Momentum HD Cold Air Intake System enhances combustion efficiency, resulting in improved throttle response and increased horsepower potential. Additionally, the system contributes to better fuel economy by optimizing airflow dynamics. Drivers will also appreciate the more aggressive intake sound, which adds an engaging auditory element to the driving experience without excessive noise.

Installation & Fitment

This intake system is a direct-fit upgrade for 2013–2018 Ram 2500 and 3500 trucks equipped with the 6.7L Cummins diesel engine. Installation requires no cutting, drilling, or complex modifications and can be completed in about an hour using basic hand tools. The kit includes all necessary hardware and detailed instructions, making it accessible for both novice and experienced installers.
