Key Features

This charge pipe kit combines advanced engineering with premium materials to deliver superior performance and durability:

• Mandrel-bent aluminum pipes for smooth transitions and minimized airflow turbulence
• Reduces pressure loss to increase horsepower and torque output
• Heavy-duty, 5-ply polyester reinforced silicone couplings for maximum strength and flexibility
• High-quality stainless-steel, spring-loaded T-Bolt clamps ensure a secure, leak-free seal
• Wrinkle black powder-coated finish for corrosion resistance and a rugged, custom appearance
• Laser-etched aFe POWER logo adds a distinctive, factory-quality look
• Designed specifically for the 6.7L Cummins engine in RAM 2500/3500 trucks from 2019 to 2023

Construction & Design

The aFe BladeRunner charge pipes are crafted from mandrel-bent aluminum, which maintains consistent diameter and smooth bends to optimize airflow and reduce turbulence. This precision engineering helps maintain boost pressure and improves engine efficiency. The pipes are coated with a durable wrinkle black powder finish that resists corrosion and wear, ensuring long-term durability even under harsh conditions.

Couplings are constructed from reinforced silicone with five layers of polyester fabric, providing excellent resistance to heat, pressure, and environmental factors. The stainless-steel T-Bolt clamps are spring-loaded to maintain consistent clamping force, preventing leaks and ensuring a tight fit throughout the life of the product.

Performance & Sound

By improving the airflow path between the turbo and engine, this charge pipe kit reduces intake air temperatures and pressure drops, which can translate into noticeable gains in horsepower and torque. The smoother airflow also enhances throttle response and overall engine efficiency. While primarily focused on performance, the upgrade may also contribute to a more refined turbo sound, complementing the aggressive character of the 6.7L Cummins powerplant.

Installation & Fitment

The aFe BladeRunner Hot & Cold Charge Pipe Kit is designed for a direct bolt-on installation with no modifications required. It fits perfectly on 2019 through 2023 RAM 2500 and 3500 trucks equipped with the 6.7L Cummins engine. Installation can typically be completed with basic hand tools and does not require specialized equipment, making it accessible for both professional installers and experienced DIY enthusiasts.
