The aFe Silver Bullet throttle body spacer bolts between the throttle body and intake manifold on the Nissan Titan, Armada, and Infiniti QX56 5.6L V8. Its serrated/helix bore creates turbulence in the incoming air charge to sharpen throttle response and build low-end torque, while the design cancels the intake whistle common to helix-only spacers. It uses the factory mounting points and works alongside aFe intake systems.
