aFe BladeRunner Intake Manifold Kit

Dodge Ram 2500 / Ram 3500 03-07 5.9L Diesel

Part #: 46-11011

Overview

The aFe BladeRunner 3.5" Intake Manifold Kit is engineered to elevate the performance of your 2003–2007 Dodge Ram 2500 or 3500 equipped with the 5.9L Cummins engine. Designed for diesel enthusiasts and racers seeking maximum airflow and enhanced engine response, this intake manifold represents a significant advancement over factory components. By optimizing air delivery, it supports increased intake volume and velocity, which translates into improved combustion efficiency and power potential.

Built with the hardcore diesel enthusiast in mind, the BladeRunner intake manifold is ideal for those looking to upgrade their engine’s breathing capabilities without compromising reliability or fitment. Its innovative design and durable construction make it a dependable choice for both street and track applications.

Key Features

The BladeRunner intake manifold incorporates advanced technology and thoughtful features to maximize airflow and functionality:

• Patented MDV (Multiple Directional Vane) technology guides air efficiently through the manifold for optimal flow dynamics.
• Constructed from cast A356-T6 aluminum for superior strength and heat resistance.
• Proprietary internal bolt design enhances airflow by minimizing obstructions inside the manifold.
• Five integrated ports, including two tapped at 1/8" NPT, accommodate nitrous injection, gauges, and other performance accessories.
• Outflows the factory intake manifold by up to 68%, delivering significantly improved air volume.
• Designed specifically for the 5.9L Cummins engine in Dodge Ram 2500/3500 models from 2003 to 2007.
• Provides a solid, leak-free seal to maintain consistent performance under demanding conditions.

Construction & Design

The BladeRunner intake manifold is crafted from premium cast A356-T6 aluminum, a material known for its excellent strength-to-weight ratio and thermal stability. This ensures the manifold withstands the high temperatures and pressures typical of diesel engine operation. The manifold’s internal architecture employs a proprietary bolt design that reduces airflow restrictions and turbulence, allowing air to move smoothly and rapidly into the engine.

The inclusion of the patented MDV technology further refines airflow by directing it through multiple vanes, optimizing velocity and distribution. This advanced engineering results in a manifold that not only increases airflow but also maintains consistent pressure and reduces the risk of hotspots or flow separation.

Performance & Sound

Testing has demonstrated that the BladeRunner intake manifold outperforms the factory unit by a remarkable 68% in airflow capacity. This substantial increase in air volume supports higher combustion efficiency and can contribute to improved throttle response and power output when paired with appropriate supporting modifications. While primarily focused on airflow and performance, the manifold’s design also helps maintain smooth engine operation without introducing unwanted noise or harshness.

Installation & Fitment

This intake manifold is a direct fit replacement for the 2003–2007 Dodge Ram 2500 and 3500 models equipped with the 5.9L Cummins engine. Installation requires standard mechanical skills and tools, with no major modifications needed to the engine bay or surrounding components. The manifold’s design ensures a secure and leak-free fit, maintaining factory mounting points and compatibility with existing sensors and accessories.
