aFe POWER Silver Bullet throttle body spacers create turbulence in the air flow just before it enters the engine, increasing horsepower and torque while improving throttle response and fuel efficiency. Silver Bullet throttle body spacers are constructed from durable T-6061 billet aluminum and utilize a unique serrated/helix entry design to create turbulence at the manifold while eliminating the annoying whistle found in other helix-only throttle spacers.
