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 Honda/Acura 2.4L K-series. 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 uses the factory mounting locations for a direct-fit install.
