aFe BladeRunner Cold Charge Pipe

2013–2018 RAM 2500/3500 6.7L Cummins

Part #: 46-20139-B

Overview

The aFe BladeRunner 3" Cold Charge Pipe is a high-performance upgrade designed specifically for the 2013 to 2018 RAM 2500 and 3500 models equipped with the 6.7L Cummins engine. Engineered by Advanced Flow Engineering (aFe), a leader in aftermarket air intake solutions, this cold charge pipe enhances airflow efficiency and durability over the factory component. It is ideal for diesel enthusiasts seeking improved throttle response, reduced turbo lag, and a more robust intake system capable of handling increased boost pressures.

Built to complement aFe’s intake and turbo systems, the BladeRunner cold charge pipe ensures a smooth, unrestricted path for compressed air from the turbocharger to the intercooler. This upgrade is perfect for those who demand reliability and performance in heavy-duty applications, whether for towing, hauling, or off-road use.

Key Features

The aFe BladeRunner Cold Charge Pipe offers several advanced features that set it apart from stock components and competing aftermarket options:

• Precision-engineered 3-inch diameter pipe for maximum airflow and reduced restriction
• Constructed from durable, high-grade aluminum for strength and heat dissipation
• Direct bolt-on fitment with OEM mounting points for easy installation
• Includes high-quality silicone couplers and stainless steel clamps for secure sealing
• Designed to withstand high boost pressures common in modified diesel setups
• Corrosion-resistant powder-coated finish for long-lasting durability
• Optimized internal surface to minimize turbulence and pressure drop
• Compatible with stock and aftermarket turbochargers and intercoolers

Construction & Design

The BladeRunner Cold Charge Pipe is crafted from premium aluminum, chosen for its lightweight properties and excellent thermal conductivity. This helps reduce heat soak, keeping intake air temperatures lower for improved combustion efficiency. The pipe’s smooth mandrel bends and precision welds ensure consistent airflow without restrictions or weak points.

Each unit undergoes rigorous quality control to meet aFe’s high standards. The powder-coated finish not only protects against corrosion but also provides a sleek, professional appearance under the hood. Silicone couplers are reinforced to resist cracking and degradation from heat and pressure, ensuring a reliable seal over time.

Installation & Fitment

Installation of the aFe BladeRunner Cold Charge Pipe is straightforward and requires no permanent modifications. It is designed as a direct replacement for the factory cold charge pipe on 2013–2018 RAM 2500 and 3500 trucks with the 6.7L Cummins engine. All necessary hardware, including clamps and couplers, is included to facilitate a secure and leak-free fit.

Typical installation time is under one hour with basic hand tools. The pipe’s design maintains proper clearance with surrounding engine components, ensuring compatibility with stock and many aftermarket setups.
