2003–2007 Dodge Ram 2500/3500 5.9L Cummins

Part #: 46-20019

Overview

The aFe BladeRunner 3" Cold 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. This charge pipe replaces the factory rear charge pipe, which is often restrictive and limits airflow to the turbocharger. By upgrading to the aFe BladeRunner pipe, owners can unlock improved throttle response, enhanced turbo efficiency, and a noticeable increase in overall engine power.

Engineered for diesel enthusiasts and performance seekers, this charge pipe is an essential component for those looking to maximize the potential of their turbocharged Cummins engine. Whether you are upgrading your intake system or simply replacing a worn factory pipe, the BladeRunner offers a direct-fit solution that delivers measurable performance benefits.

Construction & Design

The BladeRunner Cold Charge Pipe is crafted from premium materials selected for strength and longevity under demanding conditions. Its smooth mandrel-bent design minimizes turbulence and pressure drop, allowing the turbocharger to spool more efficiently. The pipe’s robust construction ensures it can handle the increased boost levels common in modified Cummins setups without cracking or deforming. Additionally, the corrosion-resistant finish protects the pipe from environmental damage, extending its service life.

Performance & Sound

By replacing the restrictive factory rear charge pipe, the aFe BladeRunner improves airflow to the turbocharger, resulting in quicker spool times and enhanced throttle response. This upgrade helps the engine breathe more freely, which can translate into a more responsive driving experience and improved power delivery throughout the RPM range. While primarily focused on performance gains, the improved airflow can also contribute to a cleaner, more efficient combustion process.
