The aFe Silver Bullet throttle body spacer bolts between the throttle body and intake manifold on 5.4L V8 Ford trucks and SUVs. Its serrated/helix entry creates turbulence in the incoming air to sharpen throttle response and build low-end torque, while the design eliminates the intake whistle common to helix-only spacers. Machined from durable T-6061 billet aluminum, it fits alongside aFe intake systems.
