aFe Throttle Body Spacer

2009–2022 Dodge Ram 5.7L Hemi

Part #: 46-32005

Overview

The aFe Throttle Body Spacer is a precision-engineered performance upgrade designed specifically for the 2009–2022 Dodge Ram equipped with the 5.7L Hemi engine. This innovative spacer enhances your truck’s air intake system by creating controlled turbulence just before the air enters the engine. The result is a more efficient combustion process that delivers noticeable improvements in horsepower, torque, and throttle response. Ideal for enthusiasts looking to maximize their Ram’s performance without extensive modifications, this throttle body spacer offers a straightforward bolt-on solution to unlock additional power and responsiveness.

Key Features

Engineered to optimize airflow and combustion efficiency, the aFe Throttle Body Spacer incorporates advanced design elements and premium materials. Key features include:

• Unique serrated/helix entry design that creates intake turbulence for improved fuel atomization
• Eliminates the intake whistle commonly found in helix-only throttle spacers
• Constructed from durable 6061-T6 billet aluminum for strength and lightweight performance
• Lengthens the intake tract to increase air intake speed and enhance throttle response
• Precision-machined for a perfect fit and finish on Dodge Ram 5.7L Hemi engines
• Improves combustion efficiency leading to increased horsepower and torque
• Simple installation with no permanent modifications required

Construction & Design

The aFe Throttle Body Spacer is crafted from high-quality 6061-T6 billet aluminum, known for its excellent strength-to-weight ratio and corrosion resistance. This material ensures durability under the demanding conditions of engine operation while maintaining a lightweight profile to avoid adding unnecessary mass. The spacer’s design features a unique serrated and helix combination entry that disrupts and swirls the incoming air, promoting better fuel atomization and a more complete combustion cycle. This innovative approach not only boosts performance but also reduces the intake whistle noise that can be distracting with other throttle spacers.

Performance & Sound

By increasing the turbulence of the air entering the combustion chamber, the aFe Throttle Body Spacer enhances the mixing of air and fuel, resulting in a more efficient burn. This leads to measurable gains in horsepower and torque, as well as a sharper throttle response that improves drivability. Unlike traditional helix-only spacers, the serrated/helix design minimizes the intake whistle, providing a more refined engine sound without unwanted noise distractions.

Installation & Fitment

Designed as a direct-fit upgrade for Dodge Ram trucks with the 5.7L Hemi engine from 2009 through 2022, this throttle body spacer installs easily between the throttle body and intake manifold. Installation requires basic hand tools and can typically be completed in under an hour without the need for modifications or tuning. The spacer includes all necessary hardware for a secure and leak-free fit, making it an accessible performance enhancement for both professional installers and DIY enthusiasts.
