The Silver Bullet throttle body spacer is constructed from precision machined 6061 - T6 billet aluminum and is designed using a serratedhelix design that creates turbulence in the airflow at the point just prior entry into the engine optimizing the combustion cycle. This turbulence helps the airfuel charge burn completely providing increased horsepower, torque and improved throttle response. During testing, Silver Bullet throttle body spacer have resulted in 4 Horsepower and 8 lbs. x ft. of torque max gains.
