它安装于节气门和发动机之间。
作用是对进入发动机内的空气进行重整，使空气在发动机内更好地与雾化汽油混合，使其燃烧更加充分，从而增加燃烧效率。
内部为锯齿/螺旋设计，使气体以涡流方式进入发动机内，让燃烧更加充分，在提升马力和扭矩的同时也提高了油门响应。

英文说明:
The Silver Bullet throttle body spacer is constructed from precision machined T-6061 billet aluminum and is designed using a serrated/helix design that creates turbulence in the air flow at the point just prior entry into the engine optimizing the combustion cycle. This turbulence helps the air/fuel charge burn completely providing increased horsepower, torque and improved throttle response. In recent testing this spacer produced 6 Horsepower and 13 lbs. x ft. of torque. This spacer was dynoed with a aFe OER air filter and dynamic air scoop.

This throttle body spacer is 50-state legal (CARB E.O Number D-550-11).
