aFe Silver Bullet Throttle Body Spacer

2007–2012 Dodge & Jeep 3.7L

Part #: 46-32010

Overview

The aFe Silver Bullet Throttle Body Spacer is a precision-engineered performance upgrade designed specifically for 2007 to 2012 Dodge and Jeep vehicles equipped with the 3.7L engine. This throttle body spacer enhances your engine’s breathing by creating controlled air turbulence within the intake manifold. The result is improved throttle response, increased air pressure in the combustion chamber, and a noticeable boost in overall performance. Ideal for enthusiasts seeking a reliable and effective way to optimize their vehicle’s intake system without extensive modifications.

By lengthening the intake track and utilizing a unique serrated/helix design, the Silver Bullet throttle body spacer delivers smoother airflow and reduces the intake whistle commonly associated with helix-only designs. This makes it a practical upgrade for drivers who want enhanced performance with a refined driving experience.

Key Features

The aFe Silver Bullet Throttle Body Spacer incorporates advanced design elements and quality materials to ensure lasting performance and durability. Key features include:

• Innovative serrated/helix design that creates air turbulence to increase combustion chamber air pressure
• Reduction of intake whistle noise compared to helix-only throttle body spacers (US Patent 07055513)
• Precision CNC machining from 6061-T6 billet aluminum for superior strength and lightweight construction
• Black anodized finish for a sleek, stealthy appearance and corrosion resistance
• Lengthens the intake track to increase intake air velocity and improve throttle response
• Utilizes all factory mounting points for a straightforward, bolt-on installation
• Includes a high-quality gasket to ensure a perfect seal and prevent air leaks

Construction & Design

The Silver Bullet Throttle Body Spacer is crafted from premium 6061-T6 billet aluminum, a material known for its excellent strength-to-weight ratio and resistance to corrosion. The spacer is CNC machined to exacting tolerances, ensuring a perfect fit and finish that matches factory specifications. Its black anodized coating not only enhances durability but also provides a clean, stealthy look under the hood.

The unique serrated and helix combination design is engineered to create controlled air turbulence inside the intake manifold. This turbulence increases the density and pressure of the air entering the combustion chamber, which helps improve combustion efficiency and throttle response without compromising reliability.

Performance & Sound

By optimizing airflow dynamics, the Silver Bullet Throttle Body Spacer helps increase intake air speed and pressure, resulting in improved throttle response and enhanced engine performance. Unlike helix-only designs, this spacer significantly reduces the intake whistle noise, providing a more refined and enjoyable driving experience. Drivers will notice smoother acceleration and a more responsive throttle feel, making it an excellent upgrade for daily drivers and performance enthusiasts alike.

Installation & Fitment

Installation of the aFe Silver Bullet Throttle Body Spacer is straightforward and requires no modifications to the vehicle. It uses all factory mounting locations, allowing for a hassle-free bolt-on installation that can typically be completed with basic hand tools. The included gasket ensures a secure, airtight seal between the throttle body and intake manifold, preventing any vacuum leaks or performance loss.

This throttle body spacer is specifically designed to fit 2007 through 2012 Dodge and Jeep models equipped with the 3.7L engine, guaranteeing compatibility and optimal performance.
