aFe Magnum FORCE Cold Air Intake System

Dodge Ram 2500 / Ram 3500 03-07 5.9L Diesel

Part #: 54-10412

Overview

The aFe Magnum FORCE Cold Air Intake System is a direct replacement for the factory air intake on 2003 to 2007 Dodge Ram 2500 and Ram 3500 trucks equipped with 5.9L or 6.7L diesel engines. Designed to enhance engine breathing by drawing in cooler, denser air, this system improves combustion efficiency, resulting in increased horsepower, torque, and overall performance. It is an ideal upgrade for diesel truck owners seeking reliable power gains without the need for extensive modifications or tuning.

By optimizing airflow and reducing intake restrictions, the Magnum FORCE system delivers a noticeable improvement in throttle response and engine efficiency. This makes it a perfect choice for daily drivers, towing enthusiasts, and off-road adventurers who demand more power and efficiency from their trucks while maintaining OEM-level fit and finish.

Key Features

Engineered to maximize airflow and filtration, the aFe Magnum FORCE Cold Air Intake System offers the following benefits:

• Pro 5R air filter featuring five layers of medical-grade cotton gauze for 98.6% filtration efficiency
• Rotomolded plastic intake tube with smooth bends to minimize airflow restriction and heat soak
• One-piece powder-coated 16-gauge aluminum heat shield that blocks engine heat and seals tightly against the hood
• Massive 4-inch flange with inverted top design for secure and stable filter mounting
• 117% increase in airflow (CFM) compared to the stock intake system
• Estimated gains of up to +18 horsepower and +24 ft-lb of torque
• Washable and reusable air filter media for long-term durability and cost savings
• Durable polyurethane sealing surfaces designed to withstand extreme engine bay temperatures
• Easy installation using factory mounting points with no cutting or drilling required
• Backed by a 2-year limited warranty and proudly made in the USA

Construction & Design

The Magnum FORCE Stage 2 intake system is crafted from premium materials to ensure durability and high performance. The intake tube is made from rotomolded plastic, chosen for its smooth internal surface that promotes laminar airflow and its resistance to heat soak, helping maintain cooler air temperatures for improved combustion.

The heat shield is constructed from heavy-duty 16-gauge aluminum with a black powder-coated finish to resist corrosion and engine bay wear. This shield effectively isolates the air filter from engine heat, ensuring the intake draws in cooler air for maximum power gains.

The Pro 5R air filter utilizes a multi-layer cotton gauze design that balances superior filtration with high airflow. Its progressive layering traps contaminants efficiently while allowing the engine to breathe freely, contributing to longer engine life and consistent performance.

Performance & Sound

By increasing the volume of cooler, oxygen-rich air entering the engine, this cold air intake system enhances combustion efficiency, resulting in noticeable improvements in horsepower and torque. The smooth airflow path reduces turbulence, allowing the engine to respond more quickly to throttle inputs. Additionally, the intake produces a subtle, aggressive induction sound that enhances the driving experience without being intrusive or overwhelming.

Installation & Fitment

The aFe Magnum FORCE Cold Air Intake System is designed for a straightforward installation process using existing factory mounting points. No cutting, drilling, or permanent modifications are necessary, making it a hassle-free upgrade for both DIY enthusiasts and professional installers. Comprehensive instructions are included to guide you through each step, ensuring a secure and proper fit on 2003–2007 Dodge Ram 2500 and Ram 3500 diesel trucks.

What's Included
