Improve throttle response, horsepower, and torque with the aFe POWER Silver Bullet Throttle Body Spacer. Featuring a precision-engineered Serrated/Helix design, this spacer enhances airflow dynamics for improved combustion efficiency while minimizing unwanted intake noise.
The Serrated/Helix entry design creates controlled air turbulence in the intake manifold, increasing air pressure in the combustion chamber. This results in improved horsepower, torque, and throttle response, while also reducing intake whistle commonly associated with helix-only designs.
CNC-machined from 6061-T6 billet aluminum, this throttle body spacer delivers lightweight strength, precision fitment, and excellent durability. A black anodized finish provides long-lasting corrosion resistance and a clean, performance-oriented appearance.
Includes a premium, high-temperature silicone coupling that meets or exceeds SAE J20 standards. The flexible coupling allows for engine movement and vibration while maintaining a secure, leak-free connection.
Designed to use factory mounting locations and included gasket, this throttle body spacer installs quickly and easily with no permanent modifications required.
