aFe BladeRunner Intake Manifold

1998.5–2002 Dodge Ram 2500 / Ram 3500 5.9L Cummins

Part #: 46-10021

Overview

The aFe BladeRunner Intake Manifold is a precision-engineered performance upgrade designed specifically for 1998.5 to 2002 Dodge Ram 2500 and Ram 3500 trucks equipped with the 5.9L Cummins diesel engine. This direct-fit manifold replaces the restrictive factory intake to dramatically improve airflow and engine efficiency, unlocking greater power potential and responsiveness.

Ideal for diesel enthusiasts and performance builders, the BladeRunner enhances horsepower, torque, and turbo response while maintaining reliable fitment and durability. Whether you are running a turbocharged setup, nitrous injection, or custom performance accessories, this intake manifold delivers optimized air delivery for improved engine breathing and throttle response.

Key Features

The aFe BladeRunner Intake Manifold incorporates advanced technology and thoughtful design elements that set it apart from both factory and aftermarket options:

• Multiple Directional Vane (MDV) technology enhances air velocity and smooths airflow paths for improved volumetric efficiency
• Constructed from cast A356-T6 aluminum for excellent strength-to-weight ratio, heat resistance, and corrosion protection
• Proprietary internal bolt design eliminates airflow obstructions and ensures a solid, leak-free seal
• Includes five ports for nitrous injection, gauges, test probes, and other performance accessories
• Comes with a crossover pipe plug and is compatible with EGR cooler delete setups
• Eliminates the factory throttle control valve to reduce airflow restrictions
• Higher arc and enlarged internal passages reduce turbulence and dead air zones for smoother airflow

Construction & Design

Crafted from premium cast A356-T6 aluminum, the BladeRunner intake manifold offers a durable, lightweight solution built to withstand the rigors of diesel performance applications. This alloy provides excellent resistance to heat and corrosion, ensuring long-lasting reliability.

The manifold’s internal architecture features smooth bends and directional vanes that create multiple airflow paths, minimizing turbulence and maximizing the volume of air delivered to the engine. Its innovative internal bolt system removes common airflow obstructions found in traditional designs, while the higher arc shape reduces sharp angles to further improve air velocity and engine breathing efficiency.

Performance & Sound

Testing shows the aFe BladeRunner Intake Manifold increases airflow by up to 90% compared to the factory manifold. This significant improvement results in faster turbo spool-up, higher boost pressure, and enhanced low-end torque. Drivers will experience a noticeable increase in engine responsiveness and power delivery, especially under load, while maintaining smooth and reliable operation.

Installation & Fitment

The BladeRunner intake manifold is a direct-fit replacement for 1998.5 to 2002 Dodge Ram 2500 and Ram 3500 diesel trucks with the 5.9L Cummins engine. Installation is straightforward and requires no major modifications. The manifold includes all necessary gaskets and detailed instructions to ensure a proper, leak-free fit. It is also compatible with EGR cooler delete kits and offers multiple accessory ports for flexible customization.
