aFe Throttle Body Spacer

Fits Most Chrysler/Dodge/Jeep/Ram 6.4L/6.1L/5.7L (05-24)

Part #: 46-32007

Overview

The aFe Throttle Body Spacer is a precision-engineered performance upgrade designed specifically for Dodge and Jeep vehicles equipped with the 5.7L Hemi and 6.4L 392 engines. This high-quality spacer enhances your engine’s air intake efficiency by creating controlled turbulence just before the air enters the combustion chamber. The result is a more complete air/fuel mixture burn, which translates into improved horsepower, torque, and throttle response.

Ideal for enthusiasts looking to maximize their vehicle’s performance without extensive modifications, this throttle body spacer works seamlessly with both the factory throttle body and select aFe POWER cold air intake systems. Whether you’re driving a Dodge Durango or a Dodge Challenger, this upgrade delivers noticeable gains in power and drivability.

Key Features

The aFe Throttle Body Spacer incorporates advanced design and materials to optimize engine performance. Key features include:

• Serrated/Helix Design: Creates intake air turbulence that breaks up fuel droplets, promoting a more complete combustion cycle for increased horsepower and torque.
• Up to +12 HP and +14 lb-ft Torque: Dyno-proven performance gains that enhance acceleration and throttle response.
• 6061-T6 Billet Aluminum Construction: Lightweight, durable, and precision-machined for a perfect fit and long-lasting reliability.
• Longer Intake Tract: Extends the intake path to increase air velocity, further improving engine breathing and responsiveness.
• Compatibility: Works with OEM throttle bodies and select aFe POWER cold air intake systems (51-12172, 54-12172, 51-12162, 54-12162) with minor intake tube modifications.
• Reduced Intake Whistle: The serrated/helix combination reduces the intake whistle commonly experienced with other helix-only designs.

Construction & Design

This throttle body spacer is crafted from premium 6061-T6 billet aluminum, known for its excellent strength-to-weight ratio and corrosion resistance. The precision machining process ensures a flawless finish and exact fitment, maintaining the integrity of your vehicle’s intake system. The innovative serrated and helix pattern on the spacer’s surface is engineered to induce controlled turbulence in the incoming air stream, optimizing the combustion process for better power delivery and efficiency.

Performance & Sound

By improving the air/fuel mixture’s combustion efficiency, the aFe Throttle Body Spacer delivers measurable performance improvements, including up to 12 additional horsepower and 14 lb-ft of torque. Drivers will notice enhanced throttle response and smoother power delivery throughout the RPM range. Additionally, the unique design reduces the intake whistle noise often associated with aftermarket spacers, providing a more refined engine sound.

Installation & Fitment

Installation is straightforward and designed to fit directly between the throttle body and intake manifold. This spacer is compatible with factory throttle bodies and select aFe POWER cold air intake systems, though some intake tube modifications may be necessary when used with aFe intakes. Detailed instructions are provided with the product to guide you through the installation process. It is recommended for installation by enthusiasts with basic mechanical skills or professional technicians.
