The aFe Silver Bullet throttle body spacer is precision machined from 6061-T6 billet aluminum and installs between the throttle body and intake manifold on the GM 5.3L V8. Its serrated/helix bore creates turbulence that helps the air/fuel charge burn more completely, sharpening throttle response and building low-end torque, without the whistle common to helix-only designs. aFe reports dyno gains up to +10 hp and +14 lb-ft on this application. It bolts to the factory locations for a direct-fit install.
