The aFe Silver Bullet throttle body spacer creates turbulence in the air flow just before it enters the engine, increasing horsepower and torque while improving throttle response and fuel efficiency. Machined from durable 6061-T6 billet aluminum, it uses a patented serrated/helix entry to generate that turbulence while eliminating the whistle common to helix-only spacers. Installation is straightforward on the Toyota 4Runner and FJ Cruiser 4.0L V6 applications listed below.
