The aFe Silver Bullet throttle body spacer installs between the throttle body and intake manifold on 4.6L and 5.4L V8 Ford trucks and SUVs. Its serrated/helix entry creates turbulence in the airflow to improve throttle response, low-end torque and efficiency, without the whistle produced by helix-only spacers. It is precision machined from durable T-6061 billet aluminum and works with aFe intakes.
