The aFe Silver Bullet throttle body spacer is a machined T-6061 billet aluminum spacer that improves airflow just before the intake manifold to boost horsepower, torque, throttle response and fuel efficiency. Its serrated helix entry creates controlled turbulence while avoiding the whistle common to other designs. Fits Toyota 4Runner and FJ Cruiser 2010–2012 with the 4.0L V6 and mates cleanly with aFe intake systems; includes a two-year limited warranty and precision machining for durable, repeatable fit.
