aFe Throttle Body Spacer

2003–2008 Dodge Ram 5.7L Hemi

Part #: 46-32002

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 performance by optimizing airflow into the intake manifold. Ideal for enthusiasts seeking a straightforward bolt-on modification, the aFe throttle body spacer improves engine efficiency without requiring complex tuning or additional components.

By creating controlled air turbulence just before the intake manifold, this spacer helps increase air pressure within the combustion chamber. The result is a noticeable improvement in throttle response and engine performance, making it a practical upgrade for daily drivers and performance-minded owners alike.

Key Features

The aFe Throttle Body Spacer incorporates advanced design and quality materials to deliver reliable performance gains. Key features include:

• Unique Serrated/Helix design that generates air turbulence to boost combustion efficiency
• Reduction of intake whistle noise commonly associated with helix-only designs
• Precision CNC machining from durable 6061-T6 billet aluminum for strength and lightweight construction
• Direct bolt-on installation using all factory mounting points for hassle-free fitment
• Includes a high-quality gasket to ensure a perfect seal and prevent air leaks
• Improves throttle response by increasing air speed entering the engine
• Designed specifically for the Dodge Ram 5.7L Hemi engines from 2003 to 2008

Construction & Design

The throttle body spacer is crafted from premium 6061-T6 billet aluminum, a material known for its excellent strength-to-weight ratio and corrosion resistance. This ensures the spacer maintains structural integrity under the demanding conditions of engine operation while adding minimal weight. The CNC-machined finish guarantees precise dimensions and a perfect fit, maintaining factory tolerances and sealing surfaces.

The innovative Serrated/Helix entry design is patented (US PAT 07055513) and engineered to create controlled air turbulence. This design not only enhances airflow dynamics but also reduces the intake whistle noise that can occur with traditional helix-only spacers, delivering a quieter and more refined driving experience.

Performance & Sound

By increasing the velocity and turbulence of incoming air, the aFe throttle body spacer improves combustion efficiency, which translates into better throttle response and enhanced engine performance. Drivers will notice a more immediate and crisp throttle feel, especially during acceleration. Additionally, the unique design minimizes intake whistle, providing a more pleasant engine sound without unwanted noise distractions.

Installation & Fitment

Installation is straightforward and designed to be completed with basic hand tools. The spacer uses all existing factory mounting locations, eliminating the need for drilling or modifications. A supplied gasket ensures a secure, airtight seal between the throttle body and intake manifold. This bolt-on design allows for quick installation, making it accessible for both professional mechanics and DIY enthusiasts.
