aFe Throttle Body Spacer

Dodge Dakota / Durango 04-10 5.7L Hemi

Part #: 46-32003

Overview

The aFe Throttle Body Spacer is a precision-engineered performance upgrade designed specifically for 2000 to 2009 Dodge Dakota and Durango models equipped with 4.7L V8 and 5.7L Hemi engines. This spacer enhances your vehicle’s throttle response and overall engine efficiency by optimizing airflow into the intake manifold. Ideal for enthusiasts seeking improved low-end torque and smoother acceleration, the aFe Throttle Body Spacer delivers noticeable gains without complex modifications.

Unlike conventional spacers, this product incorporates a patented serrated/helix internal design that creates controlled air turbulence, improving the air-fuel mixture for better combustion. It’s a straightforward bolt-on upgrade that complements both daily drivers and performance builds.

Key Features

The aFe Throttle Body Spacer stands out with innovative design and quality construction. Key features include:

• Patented serrated/helix internal design (US Patent 07055513) that generates controlled air turbulence for improved combustion efficiency
• Increases air pressure within the combustion chamber to enhance power delivery
• Improves atomization of the air-fuel mixture, promoting cleaner and more efficient combustion
• Reduces intake whistle noise commonly associated with helix-only spacers
• Lengthens the intake tract to increase air velocity, resulting in sharper throttle response and enhanced low-end torque
• Precision CNC-machined for exact fitment and seamless integration with factory components
• Constructed from lightweight, durable 6061-T6 billet aluminum for long-lasting performance and corrosion resistance

Construction & Design

Crafted from premium 6061-T6 billet aluminum, the aFe Throttle Body Spacer offers exceptional strength and durability while maintaining a lightweight profile. This material choice ensures resistance to corrosion and heat, critical for under-hood longevity. The spacer is CNC-machined to exacting tolerances, guaranteeing a perfect fit and flawless finish that complements your engine bay.

The internal serrated/helix design is a patented innovation that carefully manipulates airflow to create beneficial turbulence. This design not only improves combustion but also minimizes the intake whistle noise that can detract from the driving experience. By extending the intake tract length, the spacer naturally increases the velocity of incoming air, which translates to improved throttle response and engine efficiency.

Performance & Sound

The aFe Throttle Body Spacer enhances throttle response and low-end torque by optimizing airflow dynamics. Drivers will notice quicker acceleration and smoother power delivery, especially during initial throttle application. Additionally, the unique internal design reduces the high-pitched intake whistle often heard with other spacers, resulting in a more refined engine sound without sacrificing performance.

Installation & Fitment

Installation is straightforward and designed to fit directly between the throttle body and intake manifold on compatible Dodge Dakota and Durango models from 2000 to 2009 with 4.7L V8 or 5.7L Hemi engines. No permanent modifications or special tools are required, making it an accessible upgrade for both professional installers and experienced enthusiasts. The spacer comes with all necessary hardware to ensure a secure and leak-free fit.
