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 produces up to 8 HP and 7 lbs. x ft. of torque.
