The Silver Bullet throttle body spacer is constructed from precision machined 6061-T6 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. During testing, Silver Bullet throttle body spacers have resulted up to +10 Horsepower and up to +14 lbs. x ft. of torque max gains.
