aFe Power Silver Bullet 46-33017 Ford Throttle Body Spacer;

This Silver Bullet throttle body spacer produces 16hp and 17lbs. x ft. torque and 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. This spacer works with the OE and aFe Power cold air intake systems. Serrated/Helix Design: The Serrated/Helix combination design creates intake turbulence in the combustion chamber. This turbulence breaks up the fuel which creates a more complete combustion cycle increasing horsepower, torque and improving throttle response. The Serrated/Helix combination design also reduces intake whistle that occurs with other Helix only designs. T-6061 Billet Aluminum Construction: All Silver Bullet Throttle Body Spacers are constructed from T-6061 billet aluminum precision machined for light weight, high strength and perfect fit and finish. Longer Intake Track: Adding a Silver Bullet Throttle Body spacer lengthens the intake track which helps increase intake air speed increasing performance and improved throttle response.
