aFe BladeRunner Hot Charge Pipe

2003–2007 Dodge Ram 2500/3500 5.9L Cummins

Part #: 46-20018

Overview

The aFe BladeRunner 3" Hot Charge Pipe (REAR) is a high-performance upgrade designed specifically for the 2003 to 2007 Dodge Ram 2500 and 3500 equipped with the 5.9L Cummins engine. Engineered to replace the factory charge pipe, this product enhances airflow efficiency, resulting in noticeable gains in horsepower and torque. Ideal for diesel enthusiasts seeking improved engine response, better fuel economy, and reduced exhaust gas temperatures, the BladeRunner charge pipe delivers reliable performance enhancements without compromising durability.

By optimizing the air intake path, this charge pipe supports your truck’s turbo system more effectively, helping you unlock the full potential of your Cummins diesel engine. Whether you’re towing heavy loads or looking to improve daily driving performance, this upgrade offers a solid balance of power, efficiency, and longevity.

Key Features

The aFe BladeRunner Hot Charge Pipe combines advanced design and quality materials to maximize performance and reliability. Key features include:

• Increases horsepower by up to 16 hp and torque by 49 lb-ft as proven on the dyno
• Outflows the factory charge pipe by 67%, improving turbo efficiency
• Constructed from 3" mandrel-bent stainless steel for smooth, unrestricted airflow
• Includes 5-ply heavy-duty silicone couplings for durability and heat resistance
• Equipped with constant tension T-bolt clamps to ensure a secure, leak-free fit
• Comes with a bracket to relocate the brake line for proper clearance and fitment
• Reduces exhaust gas temperatures (EGTs) contributing to engine longevity
• Helps improve fuel economy by optimizing air delivery to the engine

Construction & Design

The BladeRunner Hot Charge Pipe is expertly crafted from premium 3-inch mandrel-bent stainless steel, providing a smooth and consistent airflow path that minimizes turbulence and pressure drop. This precision bending process preserves the pipe’s internal diameter throughout its length, ensuring maximum air volume reaches the turbocharger efficiently.

Durability is a key focus, with heavy-duty 5-ply silicone couplings designed to withstand extreme heat and pressure common in diesel applications. The constant tension T-bolt clamps maintain a tight seal under all operating conditions, preventing leaks and maintaining boost integrity. Additionally, the included brake line relocation bracket ensures the charge pipe fits perfectly without interfering with existing components.

Performance & Sound

On the dyno, the aFe BladeRunner Hot Charge Pipe delivers a significant performance boost, adding 16 horsepower and 49 lb-ft of torque over the stock setup. This increase is achieved by improving airflow efficiency and reducing restrictions in the intake path. The enhanced air delivery also contributes to lower exhaust gas temperatures, which helps protect engine components during heavy use.

While primarily focused on performance, the charge pipe’s design can also contribute to a slightly more responsive turbo spool, enhancing throttle response without altering the exhaust sound signature.

Installation & Fitment

Installation of the aFe BladeRunner Hot Charge Pipe is straightforward and designed to be a direct replacement for the factory rear charge pipe on 2003–2007 Dodge Ram 2500 and 3500 trucks with the 5.9L Cummins engine. The kit includes all necessary hardware and a brake line relocation bracket to ensure proper clearance and fitment. No major modifications or additional parts are required, making it suitable for both professional installers and experienced DIY enthusiasts.
