The aFe Silver Bullet is a billet-aluminum throttle body spacer that installs between the throttle body and intake manifold on your 3.7L Ford Mustang or F-150. Its serrated/helix design creates air turbulence in the intake manifold to raise combustion-chamber air pressure, sharpening throttle response and boosting performance while cutting the whistle of helix-only designs. It uses all factory mounting locations and includes a gasket for a direct-fit, hassle-free install.
