Construction & Design

The charge pipe kit is crafted from lightweight yet robust aluminum tubing, mandrel-bent to maintain a smooth internal diameter and eliminate airflow restrictions commonly found in factory rubber or plastic piping. This precision bending ensures consistent airflow and reduces turbulence, which can negatively impact turbocharger efficiency. The aluminum tubes are finished with a gunmetal gray powder coating that not only provides a sleek, professional look but also protects against heat, corrosion, and wear in demanding under-hood environments.

Every component is engineered to fit precisely within the Ram 2500 and 3500 engine bays, maintaining OEM mounting points and clearances for a clean, factory-quality installation.

Performance & Sound

By replacing the restrictive factory intercooler piping, the K&N Charge Pipe Kit reduces pressure drop and improves airflow from the turbocharger through the intercooler. This results in enhanced turbo spool characteristics and improved throttle response. While the primary focus is on airflow efficiency and power gains, the aluminum construction can also contribute to a subtle change in induction sound, offering a more aggressive and refined engine note under boost.

Installation & Fitment

Installation of the K&N Charge Pipe Kit is straightforward and designed to be completed with commonly available hand tools. The kit replaces the factory intercooler piping without the need for cutting, drilling, or permanent modifications, ensuring a clean and reversible upgrade. Detailed instructions are included to guide users through each step, making it accessible for both professional installers and experienced enthusiasts.

This kit is specifically engineered to fit 2013 through 2018 Ram 2500 and 3500 trucks equipped with the 6.7L diesel engine, guaranteeing a precise fit and optimal performance.
