Part #: 46-20819-B

Overview

The aFe BladeRunner AL Cold Charge Pipe is a precision-engineered upgrade designed specifically for the 2025–2026 Ram 2500 and 3500 equipped with the 6.7L diesel engine. This high-performance charge pipe replaces the factory unit to improve airflow efficiency, reduce turbo lag, and enhance overall engine responsiveness. Ideal for diesel truck enthusiasts seeking reliable power gains and a durable, custom look, this cold charge pipe delivers smooth transitions and superior strength to support your truck’s demanding performance needs.

Whether you’re towing heavy loads or pushing your Ram to its limits, the BladeRunner AL Cold Charge Pipe helps maximize horsepower and torque by minimizing pressure loss and turbulence in the intake system.

Key Features

Engineered for durability and performance, the aFe BladeRunner AL Cold Charge Pipe offers the following key features:

• Mandrel-bent aluminum construction for smooth airflow and reduced turbulence
• 3.5-inch diameter pipe optimized for the 6.7L Cummins diesel engine
• Heavy-duty, 5-ply polyester reinforced silicone couplings for superior strength and flexibility
• Stainless-steel, spring-loaded T-Bolt clamps ensure a secure, leak-free seal
• Wrinkle black powder-coated finish for corrosion resistance and a sleek, custom appearance
• Unique laser-etched aFe POWER logo adds a distinctive styling element
• Designed to fit directly onto factory mounting points with no modifications required

Construction & Design

The BladeRunner AL Cold Charge Pipe is crafted from high-grade aluminum, mandrel-bent to maintain consistent diameter and smooth airflow throughout the pipe. This precision bending reduces turbulence and pressure drops, which can hinder turbocharger efficiency. The aluminum pipe is finished with a durable wrinkle black powder coating that resists corrosion and wear, ensuring long-lasting performance and an aggressive look under the hood.

Coupled with reinforced silicone couplings and stainless-steel T-Bolt clamps, the assembly provides a robust, vibration-resistant connection that withstands the rigors of diesel truck operation. The spring-loaded clamps maintain constant pressure, preventing leaks and ensuring reliable boost delivery.

Performance & Sound

By optimizing airflow and reducing restrictions in the intake path, the aFe BladeRunner AL Cold Charge Pipe helps increase horsepower and torque output from the 6.7L Cummins engine. The smoother transitions inside the pipe reduce turbo lag and improve throttle response, contributing to a more efficient and powerful driving experience. While primarily focused on performance gains, the upgraded pipe can also contribute to a subtle enhancement in intake sound, delivering a more aggressive engine note under acceleration.

Installation & Fitment

This cold charge pipe is designed for direct bolt-on installation on 2025–2026 Ram 2500 and 3500 models with the 6.7L diesel engine. No cutting, drilling, or additional modifications are necessary, making installation straightforward for experienced enthusiasts or professional technicians. The included silicone couplings and T-Bolt clamps ensure a secure fit and easy assembly.
