The aFe Silver Bullet throttle body spacer is a precision-machined T-6061 billet aluminum spacer for Ford Ranger and Explorer SporTrac 2001–2009 with the 4.0L V6. Its serrated/helix entry creates controlled turbulence at the intake manifold to improve horsepower, torque, throttle response and fuel efficiency while avoiding the whistle common to other helix spacers. Includes a two-year limited warranty and fits with aFe intakes.
