aFe Momentum HD Cold Air Intake System

1994–2002 Dodge Ram 2500 / Dodge Ram 3500

51-72001

Overview:

The aFe Momentum HD Cold Air Intake System is engineered to deliver superior airflow and enhanced engine performance for 1994 to 2002 Dodge Ram 2500 and Ram 3500 trucks. Designed for enthusiasts and daily drivers alike, this intake system replaces the factory airbox and filter with a high-flow, sealed aluminum housing and a large Pro DRY S air filter. It provides a straightforward upgrade that improves horsepower, torque, and fuel efficiency by delivering cooler, denser air to the engine.

Ideal for those seeking a cost-effective performance enhancement without complex installation, the Momentum HD system offers a balance of power gains and reliability. Its sealed design isolates the intake from engine heat, ensuring consistent airflow and maximizing combustion efficiency.

Key Features:

This intake system incorporates advanced design elements and quality components to optimize airflow and durability:

• Outperforms the factory intake by up to 31% in airflow
• One-piece sealed aluminum housing with a built-in sight window for easy filter inspection
• Includes a high-capacity POWER Pro DRY S air filter for maximum filtration and airflow
• CAD-designed roto-molded intake tube for smooth airflow transition
• Unique filter-to-housing interface simplifies servicing and filter replacement
• No cutting or drilling required on factory parts for a hassle-free installation
• Durable powder-coated black finish resists corrosion and wear
• Flexible rubber trim seals the housing against the hood to block engine heat
• Quality stainless steel hardware included for secure mounting

Construction & Design:

The Momentum HD intake system features a rugged one-piece airbox and heat shield constructed from 16-gauge powder-coated steel, providing exceptional strength and heat resistance. The sealed housing design isolates the air filter from engine bay heat, allowing it to draw in cooler, denser air for improved combustion. The intake tube is precision-engineered using roto-molded technology to ensure smooth airflow and reduce turbulence. A specially developed three-angle velocity stack further optimizes the transition of air from the filter to the intake tube, enhancing volumetric efficiency.

Every component is built to withstand the rigors of daily driving and off-road use, with premium materials and hardware ensuring long-term durability and performance.

Performance & Sound

By increasing airflow by up to 31% over the factory intake, the aFe Momentum HD system delivers noticeable gains in horsepower and torque. The cooler air charge improves combustion efficiency, resulting in better throttle response and potential fuel economy improvements. Additionally, the intake produces a subtle, aggressive induction sound that enhances the driving experience without being intrusive.

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 airbox and filter without any cutting, drilling, or permanent modifications. The sealed housing mounts securely in the factory location, and the flexible rubber trim ensures a tight seal against the hood to prevent heat soak. Comprehensive instructions are included to guide you through each step.
