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 special serrated/helix entry that generates turbulence without the annoying whistle found in helix-only spacers, and works with aFe intakes.
