The aFe Silver Bullet throttle body spacer mounts between the throttle body and intake manifold on the Ford Mustang GT and F-250/F-350 Super Duty. Its serrated helix bore creates turbulence in the incoming air to sharpen throttle response and build low-end torque without the whistle of helix-only designs. Machined from T-6061 billet aluminum; fits models with the factory intake only.
