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.

Advanced Flow Engineering, Inc. (aFe) produces high flow, high performance air filters & intake systems for the automotive industry. Founded in April, 1999, aFe was created to address an obvious need in the automotive aftermarket industry: a lack of choice for a high performance aftermarket air filter. We are a team of engineers, machinists, production and sales people who believe in the product we design. We each have years of experience in our respective positions and together work to ensure that we have the best product on the market. Our purpose was not just to be another vendor that offers air filters, we chose to pay attention to those finer details that set an aFe filter apart from the competition.
