aFe 46-34006 SilverBullet Billet Aluminum Throttle Body Spacer 4.3L

The aFe Power 46-34006 SilverBullet Throttle Body Spacer is a bolt-on performance upgrade engineered to increase airflow speed, improve throttle response, and deliver more horsepower and torque from your GM 4.3L V6 engine. The patented serrated/helix entry design creates turbulence in the intake manifold just before the air/fuel charge enters the combustion chamber, promoting a more complete burn for optimized power output.

Key Features:

• 6061-T6 Billet Aluminum Construction: Precision CNC-machined from high-strength 6061-T6 billet aluminum for a lightweight, durable build with a precise fit and clean finish
• Patented Serrated/Helix Design (US PAT 07055513): The unique combination serrated/helix entry creates intake turbulence to optimize the combustion cycle while eliminating the intake whistle common with helix-only designs
• Improved Volumetric Efficiency: Increases the volume between the throttle body and intake manifold, improving air/fuel mixing and overall engine efficiency
• Hassle-Free Installation: Utilizes all factory mounting locations — no cutting or modification required; includes a supplied gasket for a perfect seal
