Silver Bullet throttle body spacers create turbulence in the air flow at the point just prior to entry of the engine – increasing performance, as well as improving throttle response.

The Serrated/Helix Design combination design creates intake turbulence in the combustion chamber. This turbulence breaks up the fuel which creates a more complete combustion cycle increasing horsepower, torque and improving throttle response. The Serrated/Helix combination design also reduces intake whistle that occurs with Helix only designs.
