aFe BladeRunner Cold Charge Pipe

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

Part #: 46-11013

Overview

The aFe BladeRunner 3.5" Cold Charge Pipe (Rear) is engineered to enhance the performance of your 2003–2007 Dodge Ram 2500 or 3500 equipped with the 5.9L Cummins diesel engine. Designed as a direct replacement for the factory charge pipe, this product improves throttle response and overall turbo efficiency by optimizing airflow between the turbocharger and intercooler. Ideal for diesel enthusiasts seeking reliable power gains and durability, the BladeRunner charge pipe delivers a seamless upgrade that supports both daily driving and heavy-duty applications.

By transitioning from a 3.5-inch diameter to 3 inches to perfectly mate with the factory intercooler, this charge pipe ensures a smooth, unrestricted airflow path. This results in improved boost response and reduced turbo lag, helping your Cummins engine breathe better under load.

• Mandrel-bent 3.5-inch stainless steel tube for smooth airflow and increased strength
• Powder-coated finish for corrosion resistance and long-lasting durability
• 4-ply heavy-duty silicone couplings to withstand high boost pressures and temperature extremes
• Constant tension T-bolt clamps to ensure a secure, leak-free fit under all driving conditions
• Precision transition from 3.5" to 3" diameter to fit factory intercooler without modifications
• Direct bolt-on replacement for easy installation with no cutting or welding required
• Designed specifically for 2003–2007 Dodge Ram 2500/3500 5.9L Cummins diesel engines

Construction & Design

The BladeRunner Cold Charge Pipe is crafted from mandrel-bent stainless steel tubing, providing superior strength and resistance to cracking or deformation compared to factory plastic or aluminum pipes. The powder-coated finish protects against rust and corrosion, ensuring the pipe maintains its appearance and structural integrity over time. The use of 4-ply silicone couplings enhances durability and flexibility, allowing the pipe to handle thermal expansion and engine movement without compromising the seal.

Every detail of the design focuses on maintaining optimal airflow while fitting precisely within the engine bay. The smooth bends and transitions reduce turbulence and pressure drops, contributing to improved turbocharger efficiency and quicker boost response.

Installation & Fitment

Installation of the aFe BladeRunner Cold Charge Pipe is straightforward and designed to be a direct replacement for the factory rear charge pipe. No modifications, cutting, or welding are necessary, making it accessible for both professional mechanics and experienced DIY enthusiasts. The included heavy-duty silicone couplings and T-bolt clamps ensure a tight, secure connection that resists boost leaks and maintains consistent performance.

This product is specifically engineered to fit 2003–2007 Dodge Ram 2500 and 3500 models equipped with the 5.9L Cummins engine, guaranteeing perfect compatibility and fitment.
