aFe BladeRunner Hot Charge Pipe

2019–2023 RAM 2500/3500 6.7L Cummins

Part #: 46-20618-B

Overview

The aFe BladeRunner Hot Charge Pipe is a precision-engineered upgrade designed specifically for the 2019 to 2023 RAM 2500 and 3500 models equipped with the 6.7L Cummins engine. This high-performance charge pipe replaces the factory unit to improve airflow efficiency and reduce turbo lag, resulting in enhanced engine responsiveness and power delivery. Ideal for diesel enthusiasts looking to maximize their truck’s performance without compromising reliability, the BladeRunner Hot Charge Pipe delivers smooth airflow transitions that help increase horsepower and torque.

Built to withstand the rigors of heavy-duty use, this hot charge pipe is a direct-fit solution that integrates seamlessly with your RAM’s existing turbo system. Whether you’re towing, hauling, or simply seeking improved throttle response, this upgrade offers a durable and effective way to optimize your truck’s intake system.

Key Features

The aFe BladeRunner Hot Charge Pipe combines advanced design and quality materials to deliver superior performance and durability. Key features include:

• Mandrel-bent aluminum construction for smooth airflow and minimal turbulence
• 3.5-inch diameter pipe size optimized for the 6.7L Cummins turbo system
• Wrinkle black powder-coated finish for corrosion resistance and a custom appearance
• Laser-etched aFe POWER logo for a distinctive, high-quality look
• Heavy-duty, 5-ply polyester reinforced silicone couplings for superior strength and flexibility
• Stainless-steel, spring-loaded T-Bolt clamps for secure, leak-free connections
• Designed to reduce pressure loss and improve turbo efficiency
• Direct bolt-on fitment with no modifications required

Construction & Design

The BladeRunner Hot Charge Pipe is crafted from mandrel-bent aluminum tubing, which ensures consistent diameter and smooth bends to reduce airflow restrictions and turbulence. This precision bending enhances the turbocharger’s efficiency by maintaining optimal pressure throughout the intake path. The aluminum construction also provides excellent heat dissipation, helping to keep intake air temperatures lower for improved combustion.

To protect against corrosion and wear, the pipe is finished with a durable wrinkle black powder coating that not only extends the life of the component but also adds a sleek, aggressive aesthetic under the hood. The silicone couplings are reinforced with five layers of polyester fabric, providing exceptional durability and resistance to heat and pressure. Stainless-steel T-Bolt clamps secure the couplings tightly, preventing leaks and ensuring a reliable seal even under high boost conditions.

Performance & Sound

By replacing the restrictive factory hot charge pipe with the aFe BladeRunner, you reduce pressure loss and turbulence in the intake system. This results in improved turbo spool-up and more consistent boost delivery, which translates to increased horsepower and torque. The smoother airflow path also contributes to better throttle response and overall engine efficiency. While the primary focus is on performance gains, the upgrade may also enhance the induction sound slightly, providing a more aggressive intake tone during acceleration.

Installation & Fitment

The BladeRunner Hot Charge Pipe is designed for a direct bolt-on installation on 2019–2023 RAM 2500 and 3500 trucks equipped with the 6.7L Cummins engine. No cutting, drilling, or additional modifications are necessary, making it a straightforward upgrade for experienced DIYers or professional installers. The included high-quality silicone couplings and T-Bolt clamps ensure a secure fit and easy assembly. Installation time typically ranges from one to two hours depending on experience and tools available.
