The aFe Silver Bullet throttle body spacer bolts between the throttle body and intake manifold on the Ford Ranger, Explorer, Sport Trac, and Mazda B4000 4.0L. Its serrated helix bore creates turbulence in the incoming air to sharpen throttle response, build low-end torque, and improve fuel economy without the whistle of helix-only designs. Machined from T-6061 billet aluminum.
