The aFe Silver Bullet throttle body spacer is CNC-machined from 6061-T6 billet aluminum and installs between the throttle body and intake manifold on the Toyota 3.4L V6. Its serrated/helix bore creates turbulence in the incoming air charge to sharpen throttle response and build low-end torque, without the whistle common to helix-only designs. It bolts to the factory locations using the supplied gaskets for a direct-fit install.
