aFe Throttle Body Spacer

Dodge Durango 04-09 5.7L Hemi

Part #: 46-32006

Overview

The aFe Throttle Body Spacer is a precision-engineered performance upgrade designed specifically for the 2003 to 2008 Dodge Ram equipped with the 5.7L Hemi engine. This spacer enhances your truck’s throttle response and overall engine efficiency by optimizing airflow into the intake manifold. Ideal for enthusiasts seeking improved drivability and smoother power delivery, the aFe spacer delivers noticeable gains without requiring extensive modifications.

By creating controlled air turbulence, it promotes a more complete and efficient combustion process, resulting in better fuel burn and enhanced engine performance. This throttle body spacer is a straightforward bolt-on solution that complements your Ram’s existing intake system.

Key Features

Engineered with patented technology and premium materials, the aFe Throttle Body Spacer offers several key benefits:

• Patented serrated/helix design creates controlled air turbulence for improved combustion efficiency
• Increases air pressure in the combustion chamber to optimize fuel burn
• Enhances throttle response for quicker acceleration and smoother power delivery
• Reduces intake whistle noise commonly associated with helix-only spacers
• Constructed from lightweight, high-strength 6061-T6 billet aluminum
• Precision-machined for an exact fit and reliable performance
• Finished with a durable black anodized coating for corrosion resistance and a clean appearance
• Simple installation using factory mounting points—no cutting or modifications required
• Includes custom gasket and matching aluminum tube for proper sealing and alignment

Construction & Design

The spacer is crafted from premium 6061-T6 billet aluminum, known for its exceptional strength-to-weight ratio and durability. This material choice ensures the spacer withstands the rigors of engine bay conditions while adding minimal weight. The precision CNC machining process guarantees a perfect fit that maintains factory tolerances and airflow integrity.

Its patented serrated and helix design is engineered to create controlled air turbulence inside the intake manifold. This unique airflow pattern increases air pressure and promotes a more efficient fuel-air mixture, which contributes to improved combustion and engine performance. The black anodized finish not only protects against corrosion but also enhances the visual appeal under the hood.

Performance & Sound

The aFe Throttle Body Spacer improves throttle response by optimizing airflow dynamics, allowing the engine to react more quickly to driver input. The controlled turbulence increases air pressure in the combustion chamber, leading to a more efficient fuel burn and smoother power delivery throughout the RPM range. Additionally, the design reduces the intake whistle noise often heard with other helix-only spacers, resulting in a quieter and more refined driving experience.

Installation & Fitment

Installation is straightforward and designed to be a direct bolt-on upgrade for the 2003–2008 Dodge Ram 5.7L Hemi. The spacer uses existing factory mounting locations, requiring no cutting, drilling, or other modifications. Included with the spacer is a custom gasket to ensure a secure, leak-free seal, along with a matching aluminum tube and coupling to maintain proper alignment and connection with the factory air intake system. This makes installation accessible for both professional mechanics and experienced DIY enthusiasts.
