The aFe Silver Bullet is a CNC-machined billet-aluminum throttle body spacer that mounts between the throttle body and intake manifold on your GR86 or BRZ. Its serrated/helix design creates intake turbulence for a more complete combustion cycle, improving throttle response and torque while reducing the whistle of helix-only designs. It uses all factory mounting locations for a hassle-free, direct-fit installation.
