aFe Throttle Body Spacer

2011–2025 Dodge Durango / Jeep Grand Cherokee / Jeep Wrangler 3.6L V6

Part #: 46-35003

Overview

The aFe Throttle Body Spacer is a precision-engineered performance upgrade designed specifically for the 3.6L V6 engines found in 2011–2025 Dodge Durango, Jeep Grand Cherokee, and 2012–2017 Jeep Wrangler models. This high-quality spacer enhances your vehicle’s throttle response and overall engine efficiency by optimizing airflow just before it enters the combustion chamber. Ideal for enthusiasts seeking a reliable power boost without extensive modifications, the aFe throttle body spacer delivers noticeable gains in horsepower and torque while improving drivability.

By creating controlled turbulence in the intake air, this spacer promotes a more complete and efficient combustion cycle. It works seamlessly with both factory intake systems and aFe Power cold air intakes, making it a versatile addition to your performance upgrade arsenal.

Key Features

The aFe Throttle Body Spacer incorporates advanced design and manufacturing techniques to maximize engine performance and throttle response. Key features include:

• Dyno-proven performance gains of up to +6 horsepower and +14 lb-ft of torque
• Unique serrated/helix entry design that creates intake air turbulence for improved combustion
• Reduction of intake whistle noise common with other helix-only designs
• Increased air velocity entering the engine, enhancing throttle response and power delivery
• Compatible with factory and aFe Power cold air intake systems
• Precision CNC-machined for exact fit and finish
• Lightweight yet durable construction for long-lasting performance

Construction & Design

Manufactured from premium 6061-T6 billet aluminum, the aFe Throttle Body Spacer offers exceptional strength and durability while maintaining a lightweight profile. The billet aluminum is precision CNC-machined to ensure a perfect fit and smooth finish, guaranteeing reliable installation and optimal airflow characteristics. The innovative serrated/helix design disrupts the intake air stream, creating beneficial turbulence that enhances fuel atomization and combustion efficiency. This thoughtful engineering reduces intake noise and improves overall engine performance without compromising reliability.

Performance & Sound

By increasing the turbulence of the incoming air, the throttle body spacer promotes a more complete burn of the air/fuel mixture, resulting in improved horsepower and torque output. The design also minimizes the intake whistle noise often associated with other throttle body spacers, delivering a more refined sound profile. Drivers will notice sharper throttle response and smoother power delivery throughout the RPM range, enhancing the driving experience whether on the street or light off-road conditions.

Installation & Fitment

Installation of the aFe Throttle Body Spacer is straightforward and requires no permanent modifications to your vehicle. It is designed to fit directly between the throttle body and intake manifold on 3.6L V6 engines in the specified Dodge and Jeep models. The spacer works with both stock and aFe Power cold air intake systems, maintaining compatibility and ease of installation. Basic hand tools are sufficient for installation, and the process typically takes under an hour, making it accessible for enthusiasts with moderate mechanical skills.
