Description
The Silver Bullet Throttle Body Spacer – Silver is designed to enhance airflow, increase engine performance, and improve throttle response for 2007–2013 Chevrolet Silverado 1500 and GMC Sierra 1500 equipped with the 4.3L V6 engine. By creating controlled turbulence in the intake air just before it enters the engine, this spacer optimizes combustion efficiency while minimizing unwanted intake whistle.
Crafted from precision CNC-machined 6061-T6 billet aluminum, the Silver Bullet spacer is lightweight, strong, and engineered for a perfect fit and finish. Its anodized silver finish provides a subtle yet aggressive under-hood appearance.
The proprietary serrated/helix entry design is the key to its performance. By introducing controlled turbulence in the intake manifold, this design increases air pressure in the combustion chamber, enhancing horsepower and torque, while also reducing the typical intake whistle found in helix-only designs (US PAT 07055513).
Additionally, the spacer lengthens the intake track, further increasing airflow velocity and engine responsiveness. Installation is simple and hassle-free, as the spacer uses all factory mounting locations and includes a gasket for a perfect seal with the intake system.
This throttle body spacer is compatible with stock intake systems only and is not CARB exempt, making it unavailable for sale or use in California.
